What you get

You get fewer idle apps without cutting off downloads or meetings.

Aion gives you fewer unused apps running on your Mac without making you check and quit each one yourself. Before closing an app, it checks for ongoing activity, so your downloads, music, videos, camera, microphone, and meetings stay protected rather than being stopped by a timer alone.

You decide which apps can close, how long they can sit idle, and which should always stay open. You can also schedule specific apps to quit or change cleanup behavior with your macOS Focus mode, so your rules match different parts of your day.

When you want to check what happened, you can see which apps are still running, why an app is protected, and a history of cleanup decisions. Your usage history and the decisions based on it stay on your Mac.

  • Less manual cleanup

    You stop having to find and quit apps you’ve left idle.

  • Keep ongoing work running

    Your downloads, playback, and calls stay protected while unused apps close.

  • Keep essential apps open

    You choose exceptions and individual idle timers instead of applying the same rule to every app.

  • Match your daily routine

    You can schedule app closures and adjust cleanup behavior through your macOS Focus modes.

  • Understand each cleanup

    You can review why apps stayed open or closed, with your activity history kept locally.

Best for

  • You regularly leave unused apps running
  • You want automatic cleanup without interrupting downloads or calls
  • You want different cleanup rules for work and downtime

Skip it if

You don’t need it if you already quit unused apps yourself and rarely leave anything running unnecessarily.
