The difference between deleting and uninstalling
Removing an app completely means uninstalling it so it no longer takes up storage space and no longer runs in the background. On most devices, simply deleting the app icon from your home screen does not remove it — the app files stay on your device and continue to use storage. A true uninstall removes the entire app and its associated files.
Some apps also leave behind cached data and app settings even after uninstalling. Cached data is temporary files the app created while running. Settings are your preferences within that app. Removing these leftover files completely frees up all the space the app was using.
Key Takeaways
- Deleting an app icon from your home screen does not remove the app — you must uninstall it through your device settings to actually remove the files.
- On Android, go to Settings > Apps, find the app, and tap Uninstall; on iPhone, press and hold the app icon and select Remove App, then choose Delete App.
- After uninstalling, you can clear cached data and app settings through your device storage settings to remove all remaining files.
- Some apps cannot be uninstalled because they came pre-installed with your device, but you can usually disable them to hide them and stop them from running.
- Reinstalling an app later is simple — you can download it again from your app store using the same account you used before.
How to uninstall on Android
Open Settings on your Android device. Scroll down and tap Apps (sometimes labeled Applications or Installed Apps depending on your device). Find the app you want to remove in the list and tap it. You will see an Uninstall button at the top of the screen — tap it and confirm when prompted.
If the Uninstall button is grayed out, the app came pre-installed with your device and cannot be removed. Instead, tap Disable to turn it off. A disabled app will no longer appear on your home screen and will not run in the background, though the files remain on your device.
After uninstalling, you can clear the app's remaining data. Go back to Settings, tap Apps, find the app name in the list (it may still appear), and tap Storage. Select Clear Cache and Clear Storage to remove all leftover files. If the app no longer appears in the list, it has been completely removed.
How to uninstall on iPhone
Press and hold the app icon on your home screen until a menu appears. Tap Remove App. A second menu will ask whether you want to remove the app from your home screen only or delete it entirely — select Delete App. Confirm by tapping Delete when prompted.
You can also uninstall through the App Store. Open the App Store app, tap your profile icon in the top right, find the app under Purchased, swipe left on it, and tap Delete. This method removes the app from your device and your purchase history.
iPhone does not store cached app data the way Android does, so uninstalling removes nearly all files associated with the app. However, some apps may store data in iCloud or in your iPhone's general storage. If you want to be thorough, go to Settings > General > iPhone Storage, find the app in the list, and tap it to see how much space it is using. After you uninstall, check this list again to confirm the space has been freed.
Removing apps on Windows and Mac
On Windows, go to Settings > Apps > Apps & Features. Find the program in the list, click it, and select Uninstall. A window may open asking you to confirm — follow the prompts to complete removal. Some programs include their own uninstaller, which will launch automatically.
On Mac, the simplest method is to open Finder, click Applications in the sidebar, find the app, and drag it to the Trash. Empty the Trash to permanently remove it. For more thorough removal, you can use the app's own uninstaller if it has one — check the Applications folder for an Uninstall or Installer file.
Both Windows and Mac may leave behind preference files and support folders after uninstalling. On Windows, these are usually harmless and take minimal space. On Mac, you can search for leftover files by opening Finder, pressing Command+Shift+G, and typing the app's name to locate any remaining folders, then delete them manually. This step is optional unless you want to free up every last bit of space.
What to do if an app will not uninstall
On Android, if an app cannot be uninstalled, it is a system app that came with your device. Tap Disable instead of Uninstall. Disabling stops the app from running and removes it from your app drawer, though the files remain. If you later change your mind, you can re-enable it through the same Settings menu.
On iPhone, all apps can be deleted except a small set of core apps like Phone, Messages, and Settings. If you cannot delete an app, it is one of these built-in apps. You can hide it by creating a separate folder and moving it there, or by using Focus modes to prevent it from showing notifications.
On Windows, some programs require administrator permission to uninstall. Right-click the program in Apps & Features and select Uninstall, then choose Run as administrator if prompted. If a program still will not uninstall, it may be running in the background — close it completely first by checking your taskbar and system tray, then try again.
Reinstalling an app you removed
Reinstalling an app is straightforward. On Android, open the Google Play Store, search for the app by name, and tap Install. On iPhone, open the App Store, search for the app, and tap the cloud icon with a download arrow. On Windows, visit the Microsoft Store or the app's official website. On Mac, check the App Store or the developer's website.
When you reinstall, you will usually sign back in with the same account you used before. Many apps will restore your previous settings and data automatically. Some apps store data in the cloud, so your preferences may reappear without you doing anything. Others start fresh, so you may need to reconfigure settings.
Frequently Asked Questions
Does uninstalling an app delete my data and settings?
Usually yes, but it depends on the app. Most apps store their data locally on your device, and uninstalling removes it. However, some apps back up your data to the cloud or to your account, so your information may still exist on the app's servers. When you reinstall, you can often sign in and recover that data.
Will uninstalling an app free up storage space?
Yes, uninstalling removes the app files and frees up the space they were using. On Android, clearing cached data and storage after uninstalling removes any remaining files. On iPhone, uninstalling removes nearly all associated files automatically. On Windows and Mac, uninstalling removes the program, though some preference files may remain and take minimal space.
Can I uninstall a pre-installed app that came with my device?
On Android, pre-installed apps usually cannot be uninstalled, but you can disable them to hide them and stop them from running. On iPhone, most pre-installed apps cannot be deleted, but you can hide them in folders or use Focus modes. On Windows and Mac, you can uninstall most pre-installed programs, though some core system programs cannot be removed.
What is the difference between clearing cache and uninstalling?
Uninstalling removes the entire app and its files. Clearing cache removes only temporary files the app created while running, leaving the app itself installed. Clearing cache frees up some space but does not remove the app. You typically clear cache when an app is misbehaving or to free up space without losing the app.
Do I need to restart my device after uninstalling an app?
No, restarting is not necessary. The app stops running immediately after uninstalling. However, restarting can help if an app was stuck in the background or if your device feels sluggish after removing several apps.
