Download
Click the button — about 60 MB, signed and notarized.
Drag to Applications
Open the .dmg and drag Sitful into your Apps folder.
Open Sitful
Look for the live posture score in your menu bar.
What you’re getting
A live posture score, the moment you sit down.
No setup beyond a 15-second calibration. Sitful tracks your head and shoulders in real time and nudges you — calmly — only when you’ve genuinely slipped.
Install FAQ
Good to know.
Why does macOS warn me about this app?
It shouldn’t — Sitful is signed with our Apple Developer ID and fully notarized. If you see a warning, you may have a tampered copy. Re-download from sitful.app.
What permissions will it ask for?
Camera (to score posture), Motion (only if you opt into AirPods), and Notifications (for the gentle nudges). All are skippable.
How big is the download?
About 60 MB. Trivial for what it does.
