What blocking an app actually does
Blocking an app means preventing it from running, sending notifications, or accessing certain parts of your device. The blocked app stays installed but stops working until you unblock it. On phones, blocking usually stops notifications and background activity. On computers, it can prevent the program from launching at all, or restrict what it can see and do.
The method depends on what you want to stop. If you want to silence notifications without removing the app, that is different from preventing it from using your camera. If you want to stop a child from opening an app, that requires parental controls. Understanding what you are trying to prevent will tell you which blocking method to use.
Key Takeaways
- Blocking an app on Android means turning off notifications and background activity in Settings, which keeps the app installed but inactive.
- On iPhone, you can restrict app access to specific features like the camera or location, or use Screen Time to prevent the app from opening entirely.
- On Windows, you can uninstall the app, disable it from starting automatically, or use parental controls to prevent a user account from opening it.
- Blocking an app is different from uninstalling it — the app remains on your device but stops functioning until you reverse the block.
Blocking an app on Android
Open Settings, then go to Apps or process Manager (the exact name varies by phone maker). Find the app you want to block and tap it. You will see options like Disable, Force Stop, or Uninstall. Tap Force Stop to shut it down when ready, then tap Disable if that option appears — this prevents the app from restarting on its own.
To stop notifications without disabling the whole app, tap Notifications in the same app settings screen and toggle off Allow Notifications. You can also tap Permissions to block the app from accessing your camera, microphone, location, or contacts. This keeps the app usable but prevents it from doing specific things.
If you want to block an app for a specific user account or child, go to Settings > Digital Wellbeing and Parental Controls (or just Parental Controls). Set up a child account, then use the controls to prevent that account from opening certain apps entirely.
Blocking an app on iPhone
To stop an app from sending notifications, open Settings > Notifications, find the app, and toggle off Allow Notifications. The app will still work, but you will not see alerts from it.
To restrict what an app can access, go to Settings and scroll down to find the app name. Tap it and you will see toggles for Camera, Microphone, Location, Photos, and other features. Turn off any permission you want to block. The app cannot use those features even if it tries.
To prevent someone from opening an app entirely, use Screen Time. Go to Settings > Screen Time > App Limits and set the time allowed to zero, or go to Restrictions and toggle off the app category. You can also use Screen Time > Content & Privacy Restrictions to require a passcode before opening specific apps.
Blocking an app on Windows
The simplest method is to uninstall the app. Go to Settings > Apps > Apps & Features, find the app, and click Uninstall. This removes it completely, though you can reinstall it later if you change your mind.
If you want to keep the app installed but prevent it from starting automatically, open Task Manager (press Ctrl + Shift + Esc), go to the Startup tab, find the app, and click Disable. The app will not launch when you start your computer, but you can still open it manually if you need to.
To block an app from running on a specific user account, use Parental Controls. Go to Settings > Accounts > Family & other users, select the child account, click App restrictions, and toggle off the apps you want to block. That user will not be able to open those programs.
Blocking an app on Mac
To stop an app from launching, open System Preferences (or System Settings on newer Macs) > General > Login Items. Find the app and click the minus button to remove it from the startup list. The app will not open when you restart your Mac, but you can still launch it manually.
To prevent notifications, open System Preferences > Notifications, find the app, and uncheck Allow Notifications. To restrict what an app can access, go to System Preferences > Security & Privacy and look for options like Camera, Microphone, and Location. Uncheck the app next to any permission you want to block.
If you want to block an app for a child account, create a child user account in System Preferences > Family Sharing, then use Parental Controls to restrict which apps that user can open.
The difference between blocking and uninstalling
When you block an app, it stays on your device but stops working. You can turn the block off at any time and the app will work again when ready. When you uninstall an app, you remove it completely from your device. You would need to read and install it again to use it.
Blocking is useful when you want to stop using an app temporarily, prevent a child from opening it, or keep it from using your camera or location. Uninstalling is better if you never plan to use the app again and want to free up storage space. Some apps cannot be uninstalled (like built-in system apps on Android), so blocking is your only option.
What happens when you block an app
A blocked app cannot send you notifications, run in the background, or use your device's features like the camera or microphone. It will not appear in your notification panel or drain your battery. If the app is blocked from opening entirely, tapping it will do nothing — the app straightforward will not start.
The blocked app is still taking up storage space on your device because the files are still there. If you want to free up that space, you need to uninstall it instead. Blocking is purely about stopping the app from functioning, not about removing it.
Frequently Asked Questions
Can I block an app without uninstalling it?
Yes. On Android, use Force Stop and Disable in Settings. On iPhone, use Screen Time or turn off permissions. On Windows and Mac, use parental controls or remove it from startup. The app stays installed but stops working until you reverse the block.
Will blocking an app save battery life?
Yes, if the app was running in the background. Blocking stops background activity and notifications, which reduces battery drain. The amount saved depends on how much the app was doing behind the scenes.
Can someone unblock an app I blocked for them?
On parental control accounts, no — they cannot unblock apps without the parent's passcode or password. On a regular account where you disabled notifications or permissions, the person with access to Settings can change those back.
What is the difference between disabling and force stopping an app on Android?
Force Stop shuts down the app when ready but it can restart on its own. Disable prevents it from running at all and removes it from your app drawer. Disable is the stronger block and is what you want if you do not plan to use the app.
If I block an app, will it still use my data?
A fully blocked app will not use data. If you only turned off notifications but left the app enabled, it might still use data in the background depending on what it does. Check your app's permissions to see what it can access.
