Aion – Auto-quits idle Mac apps without disrupting active tasks

Summary: Aion is a native macOS menu bar app that automatically quits truly idle applications while safeguarding active processes like downloads, calls, and media playback. It operates locally on macOS 14+ (Intel and Apple Silicon) without telemetry and offers both free and one-time Pro options.

What it does

Aion monitors app activity beyond idle timers, checking for media playback, download or IO activity, and call usage before quitting apps. It ensures only inactive apps are closed.

Who it's for

Mac users seeking to free resources by auto-quitting idle apps without interrupting ongoing tasks.

Why it matters

It prevents premature quitting of apps that appear idle but are performing important background activities.
