What deleting an app actually does
Deleting an app removes the program and its files from your device. When you delete an app, you free up the storage space it was using — sometimes a significant amount if the app was large. The app stops appearing on your home screen or in your programs menu, and you can no longer open it unless you install it again.
The process differs slightly depending on whether you use an iPhone, Android phone, Windows computer, or Mac. The core idea is the same: you find the app and remove it. On phones, deleted apps can usually be reinstalled from the App Store or Google Play Store without paying again if the app was free. On computers, reinstalling typically means downloading from the publisher's website or an app store again.
One thing to know: deleting an app does not automatically delete the account you created inside that app. If you had a login for a social media app or email app, that account still exists on the company's servers. You would need to delete the account separately if you want it gone entirely.
Key Takeaways
- Deleting an app removes it from your device and frees up storage space, but you can reinstall it later from the App Store, Google Play, or the publisher's website.
- On iPhones, press and hold the app icon, then tap "Remove App" and confirm; on Android, long-press the icon and drag it to "Uninstall" or use the Settings menu.
- On Windows computers, go to Settings > Apps > Apps and Features, find the app, and click "Uninstall"; on Mac, drag the app to the Trash or use the Applications folder.
- Deleting an app does not delete your account or data stored on the company's servers — you must delete those separately if you want them removed.
- Some apps that came with your device cannot be deleted, only disabled or hidden, depending on your device type.
How to delete apps on an iPhone
On an iPhone, press and hold the app icon on your home screen until a menu appears. Tap "Remove App" from the menu. A second menu will ask you to confirm — tap "Remove from Home Screen" if you want to keep the app installed but hidden, or tap "Delete App" to remove it entirely. If you choose "Delete App," the phone will ask one more time to confirm you want to delete it.
If you cannot see the app on your home screen, it may be in a folder or on another page. Swipe left or right to find it, or use Spotlight Search: swipe down from the top of the screen and type the app's name. Once you find it, press and hold it and follow the same steps.
After deletion, the app is gone from your phone. If you change your mind later, you can reinstall it by opening the App Store, tapping the search icon at the bottom, finding the app by name, and tapping the cloud icon with a read arrow to reinstall it.
How to delete apps on an Android phone
On an Android phone, the method depends on your phone's manufacturer, but the most common way is to press and hold the app icon on your home screen. A menu will appear with options. Look for "Uninstall" or "Remove" and tap it. The phone will ask you to confirm the deletion.
If you do not see an uninstall option in the menu, try this alternative: go to Settings, then Apps or process Manager. Find the app you want to delete in the list, tap it, and look for an "Uninstall" button. Tap it and confirm.
Some apps that came with your phone cannot be deleted — you can only disable them. If you see a "Disable" button instead of "Uninstall," that means the app is built into your phone's system and cannot be fully removed. Disabling it hides the app and stops it from running in the background, which is usually enough.
How to delete apps on a Windows computer
On a Windows computer, go to Settings by clicking the Start button and typing "Settings," then opening the Settings app. In Settings, click "Apps," then "Apps and Features." Scroll through the list to find the app you want to delete, click it once to select it, and then click the "Uninstall" button that appears.
A window may pop up asking you to confirm the uninstall or to choose options for how the app should be removed. Follow the prompts and click "Uninstall" or "Next" as needed. The app will be removed from your computer.
If you cannot find the app in Settings, it may be an older program. Try right-clicking the app's icon on your desktop or in your Start menu and looking for an "Uninstall" option. Some older programs also come with their own uninstaller — look in the program's folder for a file called "Uninstall.exe" and double-click it.
How to delete apps on a Mac
On a Mac, the simplest way is to open Finder and click "Applications" in the sidebar. Find the app you want to delete, click it once, and then press Command+Delete. A dialog will ask you to confirm — click "Move to Trash." The app is now deleted.
Alternatively, you can drag the app directly to the Trash. Open Finder, go to Applications, find the app, and drag it to the Trash icon in your dock. The app moves to Trash when ready.
After you delete an app, it sits in your Trash until you empty it. To permanently remove it from your Mac, right-click the Trash icon in your dock and select "Empty Trash." Until you do this, you can still recover the app by opening Trash, finding it, and dragging it back to Applications.
What happens to your data when you delete an app
When you delete an app from your phone or computer, the app's files are removed from your device. However, any data you created inside that app — messages, photos, notes, or settings — may still exist on the company's servers if the app synced that data to the cloud.
For example, if you delete the Gmail app from your phone, your emails remain in your Gmail account on Google's servers. If you delete a photo editing app, any photos you edited and saved to the cloud remain there. The app itself is gone, but your account and its data are not.
If you want to delete your account and all associated data, you need to do that separately through the company's website or settings. Look for an account settings page or privacy settings within the app before you delete it, or visit the company's website and look for options to delete your account.
Apps that cannot be deleted
Some apps come built into your phone or computer and cannot be deleted. On iPhones, apps like Settings, Phone, and Messages cannot be deleted. On Android phones, the system apps vary by manufacturer, but typically include Phone, Contacts, and Messages. On Windows, apps like Settings and File Explorer cannot be deleted.
If you do not want to see these apps, you can hide them. On an iPhone, press and hold the app and tap "Remove App," then choose "Remove from Home Screen" — the app stays on your phone but disappears from your home screen. On Android, you can disable system apps through Settings > Apps, which hides them and stops them from running.
On Windows and Mac, system apps are usually not visible on your desktop or in your Applications folder, so there is nothing to hide. They run in the background to keep your computer working.
Frequently Asked Questions
Will I lose my data if I delete an app?
Data stored on the company's servers — like emails, photos in cloud storage, or social media posts — remains safe. Data stored only on your device, like notes you wrote in a notes app that does not sync to the cloud, will be deleted. Check the app's settings before deleting it to see if your data syncs to the cloud.
Can I reinstall an app I deleted?
Yes. On iPhones and Android phones, go to the App Store or Google Play Store, search for the app by name, and tap the read or install button. On Windows and Mac, visit the publisher's website or an app store and read it again. Free apps can be reinstalled at no cost.
Why is my phone still slow after deleting apps?
Deleting apps frees up storage space, but it does not always make your phone faster. Slowness is usually caused by too many apps running in the background, not by the number of apps installed. Try restarting your phone, closing unused apps, or clearing your cache through Settings instead.
What is the difference between deleting and disabling an app?
Deleting removes the app entirely from your device. Disabling hides the app and stops it from running, but the app files remain on your device. You cannot disable most apps you downloaded — only system apps that came with your phone. Disabling takes up less storage than deleting but frees up less space.
Do I need to delete an app before I sell my phone?
You should delete all your personal apps and reset your phone to factory settings before selling it. This removes your accounts, data, and any personal information. On iPhone, go to Settings > General > Transfer or Reset > Erase All Content and Settings. On Android, go to Settings > System > Reset Options > Erase All Data.
