| What makes it different | - Stops each process type the way its own tool does (simctl, adb, docker) instead of force-killing
- Groups processes by type (simulators, emulators, daemons, containers, servers) unlike Activity Monitor which lists raw processes
- Pay once, no subscriptions or recurring charges
- Free tier includes full menu bar app with stopping and Clean slate; Pro only adds automatic rules and extras
- Never stops databases, builds in progress or system processes without confirmation
| - Scheduled re-checking of all facts on a regular basis, unlike the official registry which only checks on publication
- Every fact shown with its source and the date checked
- No ads, sponsors or paid placements; income never changes listings or rankings
- Corrections publicly logged and requests always answered with reasoning
- Open API accessible to everyone without authentication key
