Aion
Auto-quits truly idle Mac apps, safely
Aion is an auto-quit manager for macOS 14+. It closes apps you left open but stopped using, after checking what they are doing: downloads, playback, microphone and camera use, plus local scripts and agents, stay protected. Quitting uses standard macOS flows, so apps can still prompt about unsaved work.
The free tier covers basic auto-quit, whitelist/blacklist, resource insights, 2 focus modes and 3 app rules. Pro adds unlimited focus modes and rules, playback/mic/camera protection, automation protection and iCloud sync: $14.99 for one Mac, $24.99 for up to three. The vendor states app monitoring and rule decisions run locally. Refunds within 14 days.
Why no subscription? Pro is a one-time purchase with lifetime updates under the current policy, and the free version stays free. Aion is also offered through the paid Setapp membership — that route is a third-party subscription.
