The fastest way depends on what device you're using
Deleting an app is different on Windows, Mac, iPhone, and Android — each system stores and removes programs differently. On Windows, you go through Settings. On Mac, you drag the app to Trash or use an uninstaller. On iPhone, you press and hold the app icon until a menu appears. On Android, you open Settings, find Apps, select the one you want gone, and tap Uninstall. The steps take less than a minute once you know where to look.
The reason deletion works differently across devices is that each operating system manages files in its own way. Windows keeps app files scattered across multiple folders, so the Settings removal tool finds and deletes them all at once. Mac apps often live in a single Applications folder, so you can sometimes just drag one to Trash. Phone apps are more contained, which is why the process is simpler there.
Key Takeaways
- On Windows, open Settings, go to Apps, find the app you want to remove, and click Uninstall.
- On Mac, drag the app from Applications to Trash, or use the app's own uninstaller if it has one.
- On iPhone, press and hold the app icon, tap Remove App, then tap Delete App to confirm.
- On Android, open Settings, tap Apps, select the app, and tap Uninstall.
- Some apps leave behind files or settings even after deletion; restarting your device clears most of these.
Deleting apps on Windows
Open Settings by pressing the Windows key and typing "Settings," then click the Settings app. Once it opens, click Apps on the left side, then Apps & features. Scroll through the list until you find the app you want to remove, click it once to select it, and a button labeled Uninstall will appear. Click that button, and Windows will walk you through removing it.
Some apps ask for permission before they delete — this is normal. If the app asks whether you want to keep your settings or data, choose what makes sense for you. If you might use the app again someday, keeping the settings saves you from reconfiguring it. If you're removing it because it was causing problems, deleting everything often helps.
After the uninstall finishes, restart your computer. This clears out any leftover files the app may have left behind and frees up the space it was using.
Deleting apps on Mac
The simplest way is to open Finder, click Applications in the sidebar, find the app you want to delete, and drag it to the Trash. Empty the Trash afterward by right-clicking the Trash icon in the dock and selecting Empty Trash. The app is now gone.
Some Mac apps come with their own uninstaller — a separate program that removes the app more thoroughly. If the app folder contains an Uninstaller file, double-click it and follow the prompts instead of dragging to Trash. This method catches leftover files that dragging might miss.
If you can't find an app in Applications, it may be installed in a different location. Open Finder, click the search icon in the top right, type the app's name, and see where it shows up. Once you find it, drag it to Trash the same way.
Deleting apps on iPhone
Press and hold the app icon on your home screen until a menu pops up. Tap Remove App, then tap Delete App on the confirmation screen. The app disappears when ready. If you change your mind within 30 days, you can reinstall it from the App Store without losing any data.
If you want to remove an app but keep its data, you can also offload it instead of deleting it. In the same menu, choose Offload App. This removes the app itself but keeps your data and settings. Reinstalling it later restores everything exactly as you left it.
Some apps that came with your iPhone — like Stocks or Reminders — can be removed the same way. If you delete one by accident, you can reinstall it from the App Store for free.
Deleting apps on Android
Open Settings and scroll down to find Apps or process Manager (the exact name varies by phone brand). Tap it, then scroll through the list of installed apps until you find the one you want to remove. Tap the app name, then tap Uninstall. A confirmation screen will ask if you're sure — tap Uninstall again to finish.
Some apps that came with your phone cannot be uninstalled, only disabled. If you tap Uninstall and nothing happens, tap Disable instead. This turns off the app so it no longer runs in the background or shows up in your app drawer, though it stays on your phone.
After you uninstall an app, restart your phone to clear out any remaining files. This also frees up storage space.
What happens to your data when you delete an app
When you delete an app, the program itself is gone, but files you created inside it may remain. For example, deleting a notes app removes the app, but your notes might stay on your device in a separate folder. Photos taken in a camera app stay in your Photos library. Messages in a messaging app may stay in your Messages folder.
If you want to delete both the app and everything it created, you have to remove those files separately. On Windows and Mac, search for the app's name in your file system and delete any folders that come up. On iPhone and Android, look in your Files app or file manager for folders with the app's name, and delete those too.
If you're selling or giving away your device, restart it after deleting apps. This clears temporary files and cache that apps leave behind, which can contain personal information.
When an app won't delete
If an app refuses to uninstall, the most common reason is that something else is using it. Close all open programs first, then try again. On Windows, open Task Manager by pressing Ctrl+Shift+Esc, look for the app in the list, click it, and click End Task. Then try uninstalling again.
On Mac, open Activity Monitor by searching for it in Spotlight, find the app in the list, click it, and click the X button in the top left. Then try dragging it to Trash.
If the app still won't delete, restart your device and try once more. A restart closes everything running in the background and often solves stubborn uninstall problems. If it still doesn't work after a restart, the app may be corrupted — in that case, search online for the app's name plus "won't uninstall" to find specific steps for that particular program.
Frequently Asked Questions
Does deleting an app free up storage space?
Yes. The app itself takes up space, and so do any files it created. Deleting both frees up that space. On phones, this can make a noticeable difference if you delete large apps like games. On computers, the difference is usually smaller unless the app was very large.
Can I reinstall an app after I delete it?
Yes. On Windows and Mac, you can read it again from the publisher's website or from the Microsoft Store or Mac App Store. On iPhone, go to the App Store and search for it. On Android, open Google Play and search for it. Reinstalling is free if the app was free originally.
What if I delete an app by accident?
On iPhone, you have 30 days to reinstall it and keep your data. On other devices, reinstalling the app restores the program but not your data unless you backed it up separately. If the app had important data, check whether it syncs to the cloud — many apps save your information online automatically.
Will deleting an app stop it from running in the background?
Yes. Once an app is deleted, it cannot run at all. If an app was draining your battery or slowing down your device by running in the background, deleting it solves that problem when ready.
Do I need to restart my device after deleting an app?
It's a good idea. Restarting clears temporary files and cache that the app left behind, which frees up more space and can prevent problems. It takes a few minutes and is worth doing, especially if you deleted a large app.
