SitTall – a macOS app that uses AirPods sensors to detect slouching

I built SitTall after noticing how easy it is to slowly drift into bad posture during long desk sessions.

It’s a native macOS menu bar app that uses AirPods motion sensors to detect posture changes and sends gentle reminders when you start slouching.

No camera, no wearable beyond AirPods, no cloud processing.

I’d love feedback from HN on the concept, onboarding, pricing, or other use cases people would want from something like this.
