How to Stop iPhone Apps From Closing Without Deleting Anything

You have encountered a problem when opening an app. You see the splash screen of the app for 0.5 seconds and then you come back to your Home Screen. You try again with the same result. You are unsure if the problem is just with one app or if every app that was not obtained from Apple is affected; and you are probably aware that there is someone on a forum who has already suggested that you delete the app and re-install it.

Wait! While deleting (i.e. reinstalling) may work 90% of the time, it is one of the few steps in the troubleshooting process to lose something that cannot be recovered – and Apple has documented a process that is widely overlooked by most users.

This guide provides step-by-step instructions to troubleshoot an app starting with the least invasive option first. First you can attempt a force restart, then check the storage space on your device, check for updates, offload and reinstall. Of Note: Offloading the app removes it but maintains all of its associated documents and data. Deleting the app will also be included but is listed as the last option so that users understand what they will be losing if they choose this option. The process in this guide has been tested and verified against iOS 27, which was publicly released by Apple on 14 September 2026.

What “Closing” Actually Means on iPhone — and When It Isn’t a Crash

Four separate issues are referenced as “app closure”, with different roots and fixes. To troubleshoot, establish which issue you have first, before attempting to fix it.

Your app closes when clicking on the application from your home screen. You tap the application icon, you see a flash of the launch screen (or the app opening) and then immediately after that you are back to your home screen (the same as originally opened). The original thread for this issue on Macrumors.com has one user stating that on the iPhone 17 Pro, applications “open and then immediately close”. This is the primary example of this type of issue, and all of the other issues listed in this guide stem from this being the underlying cause of each problem.

An application closes unexpectedly while you are using it, (i.e. while scrolling or watching a video or filling out a form). This is typically due to either a low amount of free memory (memory pressure), or due to an error (bug) in the application itself.

Whenever you switch back to your app, the app reloads from scratch as if it were freshly launched. If you leave the app for just over thirty seconds and go back to it, the app starts from scratch, just like being launched for the first time. This behaviour is generally not a problem — iPhones can only maintain a small number of apps in memory, while the rest are reclaimed to free memory space for other apps; therefore, when you return, the app relaunches. This may be seen more often following the initial weeks after a major release of iOS where the operating system is indexing itself in the background; therefore, most reports of this issue following the iOS 26 release will simply be a consequence of normal usage and excessive load on the operating system at the time.

Another option to this is that the app is freezing. Simply put, the app stops responding and does not launch — if this happens, it will require a different approach to resolve the issue. The corresponding force restart procedure from the Fix section should be used.

Why “it looks like a crash” is not the same as “it crashed”

This is an important distinction, because it will tell you whether you are troubleshooting the app or the device.

When there is not enough memory available on an iPhone, it will not alert you; rather, it will terminate one or more applications. In its own documentation on jetsam events, Apple explains this process. Under conditions of memory pressure, “The operating system will free memory by terminating an application”; Apple describes this process as a jetsam event. And then, everything one has been experiencing is summed-up in the next sentence — “If your application is terminated by the system due to memory pressure and your application is visible, it looks like your application has stopped working unexpectedly.”

Therefore, while an application may appear to stop working, this may not be the case; the application may have been stopped intentionally by iOS to ensure continued operation of the device. Apple also provides a separate category for jetsam events in addition to crash reports; therefore, jetsam events are a different type of event than crashes.

This redefines the situation altogether. Reinstallation of an application does not resolve any issues if the reason is termination of the application because of lack of resources because it didn’t break in the first place. Therefore, the storage verification is the first thing to do before trying anything else with the application itself.

Another habit you can break here is using the App Switcher to quit applications as part of maintenance. Apple’s iPhone User Guide clearly articulates that iPhones inherently manage how applications operate in the background. Consequently, quitting applications that you aren’t using isn’t a valid technique for extending your battery life. In contrast, force quitting an app that is causing issues is a legitimate troubleshooting method. However, routine force quitting every app you may have used to provide yourself with battery life is not accomplishing what you may think it is.

Check Your Free Space Before You Touch the App

When an iOS device shuts down an application due to insufficient available memory, the main reason a device will shut down an application is that it does not have enough free storage space. Therefore, the first step in troubleshooting this problem is not to ask “how can I troubleshoot this application?” Instead, the question should be asked, “does my phone have enough available storage?”

To determine how much free storage space is on your phone, you can do this by going to Settings → General → iPhone Storage and waiting for the bar chart to load — you will need to wait a few seconds for the bar chart to finish and show you the available storage number in the top section of the page. Be sure to write down this available storage number so that you can refer back to it later in this process.

There is no magic number, and anyone who gives you one is guessing

You may come across various sources stating to keep 1-2 GB of free space, or 3 GB, or 5-10 GB, or 20 GB on your device but they cannot all be accurate. In addition, there are no credible sources for these claims as Apple has never issued an official minimum free space requirement for iOS, not for iOS 27 nor any previous version of iOS, and therefore this guide will not make up a minimum free space requirement.

Instead of publishing a minimum free space requirement, Apple provides an indication of when your device is approaching the point of needing to free up additional space. This notice will alert you of the need to take action to free-up space before you run out altogether.

This alert, known as Storage Almost Full, indicates that the device has reached a critical threshold and will require you to review and delete content in order to free up additional storage. Please do not swipe away or ignore these notifications as they represent a point that you have exceeded that will require you to address prior to the next notification indicating that storage has been completely consumed. Apple’s instructions for when this appears are to check the storage recommendations or remove some content.

Signal 2: The system has begun to reclaim space by itself. Apps that have a small Cloud icon next to their name in the Home Screen have been offloaded from your phone. This means that the apps were deleted, but their data was saved due to a low amount of storage space. The iPhone User Guide explains that the iPhone will automatically delete apps that are not being used, while retaining your data, if you have low storage space. The Cloud icons indicate that the iPhone has already answered your question regarding the app.

Signal 3: The Before and After Delta. After clearing out some space, check the number of apps on the device again and retest the app. This is the only indication of a direct cause/effect relationship between your device’s internal storage and how many apps you can use on it.

What to ignore while you are in there

People are led astray by two things. Other and System Data.

In addition to all the other things, Other and System Data are usually large enough to take up a number of gigabytes (for example, from 1GB to 10GB). You might think this is the source of your storage problem. Apple clearly states that seeing Other or System Data is not a reason to delete anything; these files are temporary and non-removable items that your iPhone will free up when needed for additional storage. The Apple Storage page confirms that you won’t have to free up any space by removing cached and defeatable files because your iPhone’s software automatically clears these files when your device runs low on storage space.

App sizes that appear to be incorrect; Apple has confirmed that the stored and temporary data won’t count against your usage total, which means that the total for the storage for your iPhone may not add up to the total of the apps you have installed and have recorded usage. Don’t get caught up in chasing for discrepancies!

Freeing space without deleting anything you care about

To see all recommendations in iPhone Storage, tap Show All. Review all the recommendations before selecting Enable or tapping the recommendation to get an idea of what is being removed before enabling it. The majority of recommendations are in regards to reviewing large attachments and downloaded videos that you didn’t even remember that you had, or didn’t choose to keep.

The second lever is to offload apps that you don’t use, and the fix article below covers how to do this in detail because it has both a space saving feature as well as a remediation function.

Then retest, and take the answer seriously

Create additional space to open the unresponsive app and determine if that solves the issue.

If it does, then you have discovered the root cause of your issues with this application, and the rest of this guide is optional.

If there was sufficient free space, but the application(s) continue to crash and freeze up, storage is not the cause of the issue. There was an iPhone 15 owner’s thread in the Apple Support Community where they had 66GB of free available memory and were experiencing the very same problem. Verification that storage is “not” the reason for the application’s behaviour will allow users to proceed; it will save time allowing users to stop optimizing and continue their troubleshooting process by going directly to the next section.

Confirm the App and iOS Update State

Most resources recommend that we should keep all of our software updated. While this advice isn’t wrong, it is too vague, which can cost you valuable time. There are actually three separate “update states” that can result in the same issue, and each has its own unique resolution.

State one: the app is behind the system

Every iOS major version update typically produces the same situation as iOS 27 did on September 14, 2026 (when it was released). The common situation after an iOS update is that there are some apps that haven’t yet been rebuilt for iOS’s new operating environment. These apps will exhibit behaviours that may seem like the actual device is defective.

It is best to verify that your apps have been updated, rather than depending on the automatic updates feature of the App Store. To do this, go to your App Store and tap on the profile photo at the top right corner, then under “App Updates,” verify if the app that is not opening has an available update, and update the app as necessary. You can refresh the App Store app by pulling the App Store screen down.

The information you gather from the forum can provide mixed results, and you should verify the accuracy of the information instead of just assuming it is correct. For example, one user who couldn’t open an app after upgrading reported that manually upgrading all of their apps fixed the issue. Conversely, another user who had the same app launch issue stated that manually upgrading their apps would not have worked and thus didn’t bother to take that step. Both users’ reports are legitimate. The verification process will only take thirty seconds and will give you the most accurate information on your situation.

State two: the system is behind the app

While not common, it can happen that you receive an app update designed for the current iOS version, but the app will not work properly on an older version of iOS.

To check what version of iOS is on your device: you will find information about your installed software and whether or not there are available updates in Settings > General > Software Update. Before installing the new version, make sure to do the following: create a backup of your phone before installing any new version — as suggested by Apple in their updates section — and ensure your phone is plugged into power and connected to a stable Wi-Fi network to avoid installation interruptions.

If you are currently using a beta version of iOS, you are also facing your own unique situation. When an app does not function correctly on a beta version of iOS, it is typically due to issues related to the beta release itself, which are resolved with the subsequent beta release or by reverting back to a prior stable public release of iOS.

If you recently received a warning during the update process about needing to temporarily remove apps due to insufficient storage space, it is good to know that after completing the installation of the new software, your apps will be automatically reinstalled per Apple’s standard procedure (as documented). This prompt means that you do not need to give up any of your apps; rather, the software installation will occur and the apps will be placed back on the device when finished.

State three: an update started and never finished

No one has written about the unique conditions that cause this problem, and it can have very specific symptoms for the user such as an app (which appears installed) but will not launch, an unobtrusive or faded icon (or greyed-out), or a spinner that hasn’t moved in about three hours or longer.

The documented recovery for a stuck app download is more precise than “restart and hope”:

1. Tap the app icon once to pause the download.
2. Tap it again to resume. This alone clears a large share of stalls.
3. If it will not move, touch and hold the icon and choose to cancel the download, then reinstall from the App Store.
4. On the App Store Updates screen, pull down to refresh to force the queue to re-check.

At the same time, an active VPN connection may interfere with downloading from the App Store, as well as Downloads greater than 200 MB being held back while connected via Cellular Data. Signing in with an alternate Apple ID while having the app installed creates a situation where no updates will be available.

If three-out-of-three states on an update are clean, then the problem is not related to an update — proceed to the next possibility.

Fix It Without Deleting: the iOS-Safe Order

The troubleshooting page for this issue at Apple suggests four things to do: First, close and reopen the application you had trouble with; Second, restart your device; Third, check for App Store updates; Fourth, Delete the App. Note: You may lose any information saved in the App.

There is an item that is missing between step three and step four. Apple has thoroughly documented this in another location. The term used for this process in Apple’s documentation on this subject is “Offload an App” rather than “Troubleshoot.” In Apple’s terminology, the Offload App feature “frees up storage the app occupies but continues to hold onto your files and data.” Delete an App, however, “removes the app along with any associated files and data it has accumulated.”

This distinction is the primary reason for being able to troubleshoot before deleting an application and losing that data.

There are two caveats in this document worth noting, as there are differences among apps in how they maintain data. First, there is no assurance that all apps will preserve all of their data during an offload action, since each app stores its data differently. A few apps, for instance, house their entire data set within the app bundle itself, meaning if the app is uninstalled, that same data will leave with the app. Second, you’ll only be able to reinstall an offloaded app for as long as it continues to be made available for download via the App Store. Neither of these two caveats impacts the order of the ranking. An offload action is always less destructive than deleting an app, therefore it will always be ranked higher than delete.

The order to run

Force-quit the app once using the App Switcher. Swipe across to find the app, swipe up on it to close it, and then reopen using the Home Screen. You have likely already accomplished this, but make sure you perform this cleanly one time so that it is truly a determined variable.

Step 2: Restart and, if necessary, force restart your phone if it is unresponsive. A normal restart should suffice in most cases. If your iPhone’s screen has stopped responding altogether, you can perform Apple’s documented procedure for force restarting your iPhone by pressing the volume up button, quickly releasing the button, pressing the volume down button, quickly releasing the button, and then holding down the side button until you see the Apple logo. Do not let go until after ten seconds — while this time will differ for each iPhone model, early letting go is the number one reason why many believe the procedure did not work.

This information will help you this month because iOS 27 has a soft-lock error that makes the touchscreen unresponsive. Users reported on 2026-09-16 that this error occurred after some very fast swiping between Notification Centre and Control Centre. Therefore, using the documented force-restart procedure will resolve this soft lock.

Step 3 — Offload the affected app, then reinstall it.

1. Settings → General → iPhone Storage
2. Wait for the list to populate, then tap the app
3. Tap Offload App, and confirm
4. Reinstall by tapping the app’s Home Screen icon — it stays there with a cloud symbol — or tap Reinstall App on the same Settings screen
5. Open the app

When you reinstall an app from the App Store, you will always receive the latest version of the app. Therefore, by reinstalling the app, you are essentially installing a fresh copy of the most up-to-date build of that particular application. Since iOS11, offloading will have worked this way, where the application is deleted, but the user’s documents, data and settings remain intact.

For many users, this is the step that resolves their problem and it does not cost anything to perform this action.

Step 4 — If several apps are failing, offload just one.

Unlike another possible reason I stated earlier, this one appears to be completely “counterintuitive” based on the evidence provided for it, which is mostly empirical. The original post on the MacRumors thread about apps not opening after an update about unavailable third-party apps post-update eventually lead to a reported fix by the OP on the same thread. Using the built-in function: Settings > General > iPhone Storage, the OP indicates the process of “offloading” one app resulted in them being able to open. “All 3rd party apps work now,” was stated by the OP. Three users signed up with MacRumors only to confirm they also had the same experience and had gotten the same fix by offloading an app. One user listed their failed attempts prior to their successful fix as; “Rebooting,” “Manually updating all apps,” “Toggling ScreenTime on/off,” and “Signed out of the App Store,” and all confirmed that offloading was the successful fix. A fifth reported success with this same method to reactivate third-party applications using an iPhone 17 pro by removing and reinstalling a single app.

Posts on Reddit during this same time frame showed many similar comments made by users regarding this same issue and the work-around to temporarily restore the functionality of third-party applications by offloading or re-downloading any particular third-party app.

Though this evidence is user generated and not endorsed by Apple, and comes from the small sample size of iOS 26.x builds, they are consistent across multiple independent users. Moreover, it would cost nothing to test the effectiveness of these fixes, which is the requirement of a non-destructive exercise.

Here is one limitation to understand. You cannot offload every type of app from an iOS device. For instance, the Photos app, Phone app, Safari browser, Wallet app, Messages app, and Health app cannot be offloaded or erased. The Watch app cannot be deleted if an Apple Watch is synced to an iPhone. If the option to Offload is shown in a third-party application as greyed out, quit the app completely and then try again to Offload it.

Step 6 – Only if everything fails ultimately delete it. The next level of difficulty does require payment of a fee. The following section discusses making the payment consciously as opposed to unconsciously.

A note if you also use Android

When you encounter this issue on an Android device, you are likely searching for the Clear cache button that is familiar to you from the Android operating system. Unfortunately, this feature does not exist in iOS; there is no equivalent to this option in any of the iOS Settings menus. Therefore, the best way to reset an app’s local state without deleting your data is through the offload option in iOS, which is why it plays such an important role here. We address the Android version of this problem and the order in which you should fix Android apps that keep stopping in the article entitled “The Order in Which to Fix Android Apps that Keep Stopping”.

Offload vs Delete: What You Lose, and the Only Order to Do It In

Before you delete anything, please read this: According to Apple’s statement regarding their “delete app” process: “When you delete an app, it’s deleted along with all the app’s associated data.” Their page on trouble shooting your device even says, “You may potentially lose all of the app’s stored data when you perform this action.” This is not just a generic statement. If you delete an app, you will lose everything that was kept only on your phone—such as chat history, notes, saves, and other local files and settings. If an app is reinstalled, none of its previous data remains on it. Offloading an app is a reversible process, while deleting an app is not. Therefore, take the time to review the checkpoint below before you proceed with deleting an app from your device.

Deletion of apps is not prohibited. Deletion of apps is simply the farthest point in this guide where you will incur a charge. Deletion is therefore the first point in this guide that requires you to submit payment for using it.

Why reinstalling does not bring your data back

An app’s data lives in one of three places, and only you can find out which applies:

• On the app company’s servers, tied to your account. Sign back in after reinstalling and everything reappears. This covers most streaming, email, social and banking apps.
• In that app’s own cloud backup, which is separate from your iPhone’s backup and switched on inside the app’s own settings. Messaging apps commonly work this way.
• Only on your phone. Reinstalling gives you a clean app and an empty start.

This “middle” case occurs when users get hurt through the appearance of the “first” case, and many threads exist within Apple Support Community regarding the issue; a user performs a full backup of their iPhone, reinstalls a messaging application, and then loses all of their chat history. The reason for this loss is that chat history is not part of the iPhone’s backup, but is a separate backup created by the messaging application (which was not enabled). One post specifically described the loss of years of messages from a deceased family member; that is the reason this section exists to help users avoid that cost.

The pre-delete checkpoint

Do all five. They take a few minutes and they are the difference between a fix and a loss.

1. Back up the iPhone. Settings → your name → iCloud → iCloud Backup → Back Up Now. Stay on Wi-Fi until it finishes; the date and time of the last backup appear underneath. If iCloud storage is short, back up to a Mac or PC instead — Apple documents all three routes.
2. Check whether this app’s data is actually in that backup. Settings → your name → iCloud lists the apps using iCloud. An app that is absent, or present and switched off, is not being backed up by iOS.
3. Check inside the app itself, if you can open it at all. Many apps that store data locally keep their own backup switch in their own settings. If the app opens long enough to reach them, turn it on and back up now. If it will not open, treat its local data as at risk.
4. Know your sign-in. A reinstalled app is a signed-out app. If you do not have the email address, password or phone number the account uses, recover them before deleting, not after. This is the most common way people lock themselves out of an app that was merely crashing.
5. Cancel any in-app subscription you no longer want. Apple states it plainly on its delete apps page: “If you delete an app, it doesn’t automatically cancel in-app subscriptions.” Subscriptions live at Settings → your name → Subscriptions. You can delete an app and keep paying for it indefinitely.

Then, and only then

1. Settings → General → iPhone Storage → the app → Delete App, or touch and hold the app on the Home Screen, tap Remove App, then Delete App, then Delete to confirm.
2. Redownload it from the App Store. Paid apps do not need buying again — previously downloaded apps stay attached to your Apple Account, under your account photo, in Apps & Purchase History, then Your Apps.
3. Sign back in, and restore from the app’s own backup if it offers to. Some apps only offer this once, during first-run setup. Do not tap past it.
4. Open it and test.

According to Apple’s iOS 27 guidance, you should not be concerned if you delete an app and then wait for a while for the available storage amount to update. You should not worry if the number does not change right away after deleting an app, as it may take some time for it to reflect that change.

If you cannot find the Delete option

Two documented reasons, both from Apple:

• Parental controls. If Deleting Apps is not set to Allow in Screen Time’s content and privacy restrictions, the option is hidden.
• The device is managed. If an employer or school manages the iPhone through Mobile Device Management, you may not be able to delete apps at all, and Apple’s guidance is to contact your device administrator.

That second one deserves a pause if the failing apps are work apps on a work-issued phone. The problem may not be yours to fix.

The honest summary

The first step in offloading is to do so for free, whereas the last step (deleting) requires you to pay for the contents of your application (or at a minimum, some other content). If you delete and reinstall your app but do not restore the content, then you can conclude that your attempt to fix your app was not successful because you lost the contents of your app. The whole purpose behind performing these two steps in the order prescribed is to make a conscious decision to do so for the sake of making a trade with the original contents of your app.

How to Confirm It Worked, and What to Do If It Didn’t

The app opened. That is good news, and it is not yet proof of a repair.

Confirm it properly

1. Open the app and use it for a minute. Not just the launch screen — navigate, load something, let it do real work. Launch failures and mid-use terminations share causes often enough that testing only the launch tells you half the story.
2. Test a second app, particularly if several were affected. If one opens and another still fails, the fault was never shared and you are back to the single-app path.
3. Recheck your free space. Settings → General → iPhone Storage, compared against the figure you noted earlier. If it is still very low, you have fixed a symptom and left the condition in place.
4. Come back in a day. This is the step people skip, and the one the evidence most supports.

Expect the possibility of recurrence, and know what it means

One iPhone 17 Pro user on MacRumors stated that the “offload and reinstall” solution worked, but that the problem would come back after a period of time still. A second user mentioned that the issue cleared up by itself after 48 hours, without needing to take any action.

Both users experienced similar results. The fact that the fix needs to be reapplied indicates that the fix did not actually fix anything — it was merely a temporary solution to an ongoing problem that is a fault at the operating system level. Therefore, instead of progressing with escalation through more destructive methods, you should be reporting these issues.

If it did not work — in order

Confirm if the problem described is also occurring on your phone. Apple has a live system status page that will inform you of any outages experienced by the App Store or other purchase-related services. During such an outage, an app that confirms your subscription or allows you to sign in may fail in a manner that appears to be localised to your device. Therefore, if you find an issue displayed in the system status page, you should wait instead of troubleshooting.

Review your device’s Screen Time and Restrictions settings. An app that is blocked by App Limits, Downtime or Content & Privacy Restrictions cannot be opened. To view this, navigate to Settings → Screen Time. It should be noted that, on the related source forum, a member posted with a suspicion that such a scenario might exist and that after turning off their Screen Time limits the scenario did not change, so please take that into consideration before you become too hopeful.

Determine if your phone is a managed device. As previously mentioned, a phone under Mobile Device Management may be restricted in ways that only the MDM administrator will be able to lift those restrictions.

Next, it’s best to contact the developer directly. This should be the last resort that Apple recommends you take if the app isn’t working and it isn’t impacting any other apps. The instructions are clear: “If an app isn’t working, and the problem is not affecting any other apps.” Apple’s guidance on when to contact an app developer is specific.

To do this, go to the App Store, search for the app, select it, scroll down to the Ratings & Reviews section and tap on “App Support.” If the app is not installed currently, you can access it by clicking on your profile image at the App Store, then selecting “Apps,” then selecting “My Apps” and “Not on this iPhone” to find it.

Then supply them with the information they actually need in order to assist you: Include the model of your iPhone; Include the precise version of iOS you are running, obtained from Settings > General > Software Update; Explain what happens to the app when it fails; Include when it began; Also indicate that you’ve already updated the app, updated iOS, verified storage space, offloaded then reinstalled the app. By giving developers this type of detailed report, you will be providing more useful and meaningful information than most developers receive.

If you have recently purchased an app and decided you no longer want to use it, Apple’s Troubleshooting page allows for requesting a refund to be considered an acceptable resolution. You can file your refund request through reportaproblem.apple.com: log in, select “I’d like to”, then select “Request a refund”, choose one of the reasons, select the app, and submit it. While Apple does not guarantee refunds, a purchased app that is not opening is an example of an acceptable reason.

Additionally, if “wait” is your answer, that is a valid answer! After each major version of iOS, some apps take longer to update to be compatible with the new system. If this is the issue, there are no fixes that you will be able to perform on your device until the developer releases an updated version. The best method for checking if there are any updates is by monitoring the App Store every couple of days instead of reinstalling the app multiple times.

What not to do next

Don’t erase your phone. While many users have experienced some degree of temporary success with the factory reset and restore methods for this issue, others have also reported experiencing problems after restarting their devices. Since factory resets and restores are very destructive actions and are not supported by this guide, the evidence these methods resolve long-lasting problems is minimal. If you have reached the stage where you are contemplating a factory reset or restore, you would be better off investing your time in contacting the developer as well as Apple Support.

Check This First Next Time

Most of the work above was diagnosis, not repair. Three habits will make the diagnosis collapse into around a minute next time; one of those habits eliminates the worst-case scenario completely.

Turn on Offload Unused Apps, and keep it enabled. Under Settings > Apps > App Store > Offload Unused Apps you will find this option. If you enable this feature the iPhone will automatically delete any apps you have not used if space is low on your device and it will not lose your data; only the icon remains on your Home Screen with a cloud symbol, and you can restore by tapping the icon. This feature creates an automatic “non-destructive” way to fix your phone’s problem, as long as you have not yet noticed the situation is serious enough to require your attention.

Think of the Storage Almost Full alert as a deadline rather than a nag. When this alert appears, Apple’s instruction is to either look at the storage recommendations for your device or delete some items. The moment this alert appears, the iOS system begins removing items from the iPhone’s Hard Drive to free up memory space. Clearing this alert once per month will save you lots of money compared to troubleshooting during one evening of your time.

Let your applications update automatically. Many of the thousands of apps that stop working after an iOS upgrade have not yet updated themselves. These applications will eventually catch up with the operating system through updates. By allowing your applications to be updated automatically, you can enjoy these updates without having to figure out yourself that you needed to update your application.

Backup data on a regular schedule rather than waiting until a disaster occurs. The biggest difference this makes is that every decision in this article where you have to either delete data or reinstall the application will only be difficult for you if you have no idea what has been backed up. In Settings, click on your name, select iCloud, and select iCloud Backup. Make sure that you have enabled iCloud Backup and that your phone is plugged in and connected to a Wi-Fi connection overnight. Then verify today whether or not the applications that you would be upset if you lost are backed up, and also with regards to messaging applications, if their in-app backups were turned on, because device backups may not include their data.

When you encounter an application that crashes immediately after you attempt to open it, you should take the following four steps: 1) Check for available storage space. 2) Look for an update for the application. 3) Force-quit and then restart your device. 4) Offload and reinstall the application. If you follow this sequence of steps, you will not need to delete any of the app’s files, and you will not have lost any of your data.

Frequently Asked Questions

Does offloading an app delete my data?

No. Apple states that when you offload an application, it will remove the app and free up the storage used by that app, however, it will retain all the files and data associated with said app. Therefore, once you uninstall an app, you are left with the data container on your device and when you install the app again you will have access to that data container as well. The only real exception to this rule is for those applications that store their data in the app bundle versus a dedicated document folder, which is rare, hence why you should always check your backup settings before offloading an app that is important to you.

Why do my apps reload from scratch when I switch back to them?

This is typically due to memory management, not to a crash. iOS continuously manages memory by keeping a limited number of apps open in memory and then reclaiming memory from all other apps. When you go back to an app, the app may now require to start up again since it is no longer open in memory. This can be especially prominent after an iOS upgrade as re-indexing occurs. The only time you should be concerned is when your apps are closing while you are using them actively.

How much free space does my iPhone actually need?

There is no definitive number that we can attribute to iOS 27 or previous versions of iOS published by Apple themselves. Any number you see — 3GB, 5GB, 20GB — is only based on speculation. The only signals that Apple gives us regarding low storage issues are when you get the Storage Almost Full alert and when the system begins offloading apps automatically from memory due to lack of available storage. If either of these occurs, this indicates that you’re experiencing low storage. So, measure, check for available space, and then retest your performance.

If I delete an app, do I lose the photos or files I made with it?

That isn’t exactly true. According to Apple, an app’s data that is stored in iCloud (such as photos or documents you saved through the app) will not be deleted when you delete the app itself. The only thing you’ll lose are the app’s locally stored data on your device (local settings, offline downloads, caches, and any history that was never synced back to iCloud).

Does deleting an app cancel its subscription?

No, it is a common misconception that when you uninstall an app, you will also cancel any in-app subscriptions for that app. In its support documentation, Apple clearly states that uninstalling an app will not cancel its in-app subscriptions; you must cancel the subscription through the ‘Settings’, ‘Your Name’, ‘Subscriptions’ menu before uninstalling the app to avoid continued billing for an app that is not on your device.

My whole iPhone shuts down, not just the apps. Same problem?

Another issue and separate page in Apple documentation. Apple links unexpected whole-device shutdown to a battery that no longer delivers the peak power required by the system and indicates the use of a battery replacement as a solution. There are no references in this guide to this problem. If you’re experiencing a black screen and the phone is rebooting, go to Settings -> Battery -> Battery Health and do not follow the app troubleshooting steps.

Can I offload any app?

Photos, Phone, Safari, Wallet, Messages, and Health cannot be offloaded or deleted; if you want to remove the Watch app while your Apple Watch is paired, Apple will require you to unpair the Apple Watch first. Some apps may appear with the Offload feature greyed out while they are currently running. To use Offload for that app, you need to force-quit the app and then try again with Offload after closing out.

Will I have to pay again for a paid app if I delete and reinstall it?

No. Apps that you downloaded previously remain associated with your Apple ID and can be re-downloaded from the App Store via your account profile where it shows your apps that can be purchased again. If the application has been removed from the App Store, even though it will appear in your Purchase History, it will not be available for installation; therefore, if you have an older or lesser-used application, it is always better to use Offload than to leave it on your device.
