What "totally delete" means and why it matters
Deleting an app means removing it from your device so it no longer takes up storage space and no longer runs in the background. On most phones and tablets, uninstalling an app through the normal method removes the program itself, but some leftover files called cache and app data can stay behind and still use storage. A total deletion removes both the app and those leftover files, freeing up the most space possible.
The difference matters most if you are running low on storage or if you want to completely remove all traces of an app before selling or giving away your device. For everyday use, the standard uninstall is usually enough. But if you want the app gone entirely, the steps below will get you there.
Key Takeaways
- On Android, uninstalling an app through Settings removes the program, but you may need a separate step to clear its cached data and free up all the space it used.
- On iPhone, deleting an app through the home screen removes it completely, including all its data, in one step.
- Some apps come pre-installed on Android devices and cannot be fully removed, but you can disable them to stop them from running.
- If you want to wipe an app before selling your phone, factory reset is the most thorough method on both Android and iPhone.
How to delete an app on iPhone
On iPhone, deleting an app removes the program and all its data in one action. Press and hold the app icon on your home screen until a menu appears. Tap Remove App, then tap Remove from Home Screen to delete it but keep it in the App Store, or tap Delete App to remove it entirely. When you choose Delete App, tap Delete again to confirm.
If you want to delete multiple apps at once, you can enter edit mode by pressing and holding any empty space on your home screen, then tapping the minus sign on each app you want to remove. This method removes the app from your home screen but does not delete it from your device — you will still need to tap Delete App to remove it completely.
Deleted apps can be reinstalled from the App Store at any time. Your purchase history is saved to your Apple ID, so you will not be charged again for paid apps you have already bought.
How to delete an app on Android
On Android, the process depends on whether the app came pre-installed on your device. For apps you downloaded yourself, open Settings, go to Apps (or Application Manager on older devices), find the app you want to remove, and tap Uninstall. Confirm the action when prompted. This removes the app from your device.
After uninstalling, check your storage to see if you want to clear the app's remaining data. Go back to Settings, tap Apps, find the app name again (it may still appear in the list), and tap Storage. If there is a Clear Cache or Clear Data button, tap it to remove leftover files. This step is optional but frees up additional space.
Pre-installed apps that came with your phone cannot be uninstalled on most Android devices, but you can disable them to stop them from running. Open Settings, go to Apps, find the app, and tap Disable. A disabled app will not appear on your home screen or run in the background, though it will still take up some storage space.
Clearing app cache and data on Android
App cache is temporary data that apps store to load faster next time you open them. App data includes your settings, saved files, and login information. Clearing cache frees up space but does not affect how the app works. Clearing data removes everything, including your settings and saved information.
To clear cache and data, open Settings, tap Apps, select the app, and tap Storage. You will see two options: Clear Cache removes temporary files only, and Clear Data removes everything. If you are deleting the app entirely, clearing data first is not necessary — uninstalling removes both automatically. But if you want to keep the app and just free up space, clearing cache is a safe first step.
Removing apps before selling or giving away your device
If you are selling or giving away your phone, uninstalling individual apps is not enough to ensure your data is gone. A factory reset is the most thorough method on both Android and iPhone. This erases everything on your device, including all apps, photos, messages, and personal information, and returns it to its original state.
On iPhone, go to Settings, tap General, scroll to Transfer or Reset, and tap Erase All Content and Settings. On Android, go to Settings, tap System (or About Phone on older versions), scroll to Reset Options, and tap Erase All Data. Both processes take several minutes and will ask you to confirm before proceeding. After a factory reset, the device is ready for a new user.
Before you reset, back up any photos, contacts, or files you want to keep. On iPhone, use iCloud or a computer. On Android, use Google Drive or your computer. Once the reset is complete, those items will be gone unless you have saved them elsewhere.
What happens to your data when you delete an app
When you uninstall an app on iPhone, all data associated with that app is deleted immediately. Photos taken in that app, messages, saved files, and login information are all removed. If you reinstall the app later, you will start fresh with no previous data.
On Android, uninstalling removes the app itself, but some data may remain in your device storage until you clear it manually. This is why the separate step of clearing cache and data matters on Android. If you do not clear the data, the app's leftover files will still take up space even though the app is gone. Reinstalling the app will not recover the old data — it will start fresh.
Frequently Asked Questions
Can I recover an app after I delete it?
Yes. On iPhone, you can reinstall any app from the App Store, and your purchase history is saved. On Android, you can reinstall downloaded apps from the Google Play Store. Pre-installed apps that you disabled can be re-enabled in Settings. However, any data the app stored (photos, messages, settings) will not come back unless you have a backup.
Why is an app still taking up storage after I uninstalled it?
On Android, the app's cache and data files may still be on your device. Go to Settings, tap Apps, find the app name, tap Storage, and tap Clear Cache or Clear Data. On iPhone, this should not happen — uninstalling removes everything. If storage is still missing, restart your phone and check again.
What is the difference between disabling and uninstalling on Android?
Disabling stops an app from running and hides it from your home screen, but it still takes up storage space. Uninstalling removes the app entirely. You can only disable pre-installed apps; downloaded apps must be uninstalled. If you want to free up the most space, uninstall instead of disable.
Will deleting an app remove my account or login information?
Deleting the app removes the data stored on your device, including saved passwords and settings within that app. However, your account with the service (like your email or social media account) still exists on the company's servers. When you reinstall the app, you can log back in with your username and password.
Do I need to clear data before uninstalling an app?
No. Uninstalling automatically removes the app and its data together. Clearing data first is only useful if you want to keep the app but remove your personal information from it before giving your device to someone else.
