About Aion
Aion is a context-aware auto-quit manager for macOS. It closes apps you have stopped using while checking first for downloads, media playback, calls, microphone or camera activity, unsaved work, and local automation.
Designed for everyday Mac use, Aion provides per-app timeouts, whitelist and blacklist rules, Focus Modes, resource insights, and local app-state checks. The free edition covers basic cleanup; the Pro edition adds unlimited rules and modes, expanded activity protection, automation protection, and iCloud sync.
