What resetting an app actually does
Resetting an app clears out the data it has stored on your device — login information, saved settings, cached files, and any temporary data it created while running. When you reset, the app itself stays installed, but it goes back to the state it was in the moment you first opened it. You will need to log back in and set your preferences again.
Most app problems — freezing, crashing, refusing to load, or running slowly — come from corrupted cached data or settings that got stuck. Resetting clears that out without removing the app from your device. It is different from uninstalling, which removes the app entirely and requires you to download it again from your app store.
Resetting works best when an app has stopped responding to normal troubleshooting, like closing it and reopening it, or restarting your phone. If an app crashes every time you open it or gets stuck on a loading screen, a reset is usually the next step to try.
Key Takeaways
- Resetting an app clears its stored data and settings but leaves the app installed on your device, so you will need to log back in afterward.
- On Android, go to Settings, find the app under Apps or Application Manager, and tap Clear Cache and Clear Data in that order.
- On iPhone, you cannot clear an app's cache directly — you must offload the app (which keeps your login) or delete and reinstall it (which removes everything).
- If resetting does not fix the problem, check that your app is fully updated and that your device has enough free storage space.
How to reset an app on Android
Open your device Settings and scroll down to find Apps or Application Manager — the exact name varies by phone brand. Tap it, then find the app you want to reset in the list. Tap the app name to open its details page.
On the details page, you will see buttons for Clear Cache and Clear Data. Tap Clear Cache first. This removes temporary files the app created while running but keeps your login information and settings. If that does not fix the problem, go back and tap Clear Data, which removes everything — you will need to log back in and set the app up again.
After clearing data, close Settings and open the app. It will load as if you just installed it for the first time. Log in with your username and password, and the app should work normally. If you had saved preferences or custom settings, you will need to set those again.
How to reset an app on iPhone
iPhone does not have a direct "clear cache" button the way Android does. Instead, you have two options: offload the app, which removes it temporarily but keeps your login, or delete the app, which removes everything and requires you to reinstall it.
To offload, open Settings, tap General, then iPhone Storage. Find the app in the list and tap it. Tap Offload App. This removes the app from your phone but keeps your account information and any data you saved inside it. Wait a few seconds, then go back to the home screen and tap the app icon again — it will reinstall itself and you can open it without logging in again.
If offloading does not fix the problem, you will need to delete the app entirely. On the same iPhone Storage screen, tap the app and choose Delete App, then Delete to confirm. Go to the App Store, search for the app by name, and tap the cloud icon or Get to reinstall it. You will need to log in again when you open it.
What to do if resetting does not work
If an app still crashes or freezes after you reset it, check that you have the latest version installed. Open your app store — Google Play on Android or the App Store on iPhone — search for the app, and see if an Update button appears. If it does, tap it and wait for the update to finish. Outdated versions sometimes have bugs that newer versions have fixed.
Also check how much free storage space your device has. Apps need room to create temporary files while they run. If your phone is nearly full, the app may not have enough space to work properly. On Android, go to Settings and look for Storage. On iPhone, go to Settings, tap General, then iPhone Storage. If you have less than 1 GB free, delete files, photos, or apps you no longer need.
If the app still does not work after updating and freeing up space, the problem may be with the app itself rather than your device. Check the app's support page or contact the company that makes it — they may have a known issue or a workaround specific to your phone model.
When to uninstall and reinstall instead
Resetting and uninstalling are different actions with different results. Resetting keeps the app installed and clears its data. Uninstalling removes the app entirely from your device. In most cases, resetting is faster and safer because you do not lose the app while you are troubleshooting.
Uninstall and reinstall the app only if resetting did not work, the app is severely broken, or you want to start completely fresh with no saved data or login information. Uninstalling also frees up storage space if the app is large, though the benefit is usually small unless the app is several hundred megabytes.
To uninstall on Android, go to Settings, find the app under Apps, tap it, and choose Uninstall. On iPhone, press and hold the app icon on your home screen, tap Remove App, then Delete App. After uninstalling, go to your app store and search for the app by name to reinstall it.
Why apps need resetting sometimes
Apps store temporary files called cache to load faster the next time you use them. Over time, this cache can get corrupted — especially if the app crashed while it was saving data, or if you ran out of storage space while the app was running. Corrupted cache files can cause the app to freeze, crash, or refuse to open.
Apps also store your login information and settings in a database on your phone. If that database gets damaged, the app may not remember who you are or what you chose, and it can cause errors when the app tries to read that information. Clearing the data forces the app to rebuild that database from scratch the next time you log in.
Resetting does not fix problems with your internet connection, your phone's operating system, or bugs in the app itself. It only fixes problems caused by corrupted or stuck data on your device. If an app works fine on someone else's phone but not on yours, resetting is worth trying. If it crashes on everyone's phone, the problem is with the app, not your device.
Frequently Asked Questions
Will resetting an app delete my photos or messages?
No. Resetting an app only clears data that the app itself created and stored. Your photos, messages, contacts, and other files on your device are not affected. However, if the app stores photos or messages inside itself — like a messaging app or photo editor — those will be deleted when you clear the app's data.
Do I need to log back in after clearing cache?
Clearing cache alone usually keeps you logged in. Clearing data removes your login information, so you will need to enter your username and password again. If you only want to try clearing cache first, do that before clearing data.
How often should I reset my apps?
Most people never need to reset an app unless it stops working. You do not need to reset apps regularly for maintenance. Only reset when an app is crashing, freezing, or behaving strangely, and normal troubleshooting like closing and reopening it has not worked.
Can I reset an app without losing my account?
On Android, clearing cache keeps your account. On iPhone, offloading the app keeps your account. Clearing data on Android or deleting an app on iPhone will remove your login information, and you will need to log in again after resetting.
What if the app does not appear in my settings?
Some apps are built into your phone and cannot be reset the same way. Try opening the app, looking for a Settings or Preferences option inside the app itself, and choosing an option like Reset or Clear Data from there. If the app has no reset option, try closing it completely and restarting your phone.
