# Starting, stopping, or restarting an app

Updated February 21, 2026

By default, all installed apps start automatically when umbrelOS boots. You can control this by stopping apps you don't want running.

## [Stop or restart an app](/content/support/apps/how-to-start-stop-or-restart-an-app#stop-or-restart-an-app/index.html)

Right-click the app icon on your home screen and select **Stop** or **Restart**. When an app is stopped, its icon will indicate that it's not running.

## [Start a stopped app](/content/support/apps/how-to-start-stop-or-restart-an-app#start-a-stopped-app/index.html)

Click a stopped app's icon on your home screen to start it again.

## [Prevent an app from auto-starting](/content/support/apps/how-to-start-stop-or-restart-an-app#prevent-an-app-from-auto-starting/index.html)

There's no separate auto-start setting — simply stop the app. Stopped apps stay stopped even when you reboot your Umbrel. This makes it easy to keep apps installed without having them use resources in the background. When you're ready to use the app again, just click it to start it.
