Stop slouching, not pinging
Timer-based "sit up straight" reminders lose their bite fast — your brain tunes them out. Posturion fires only when forward head, shoulder tilt, or head tilt actually crosses your threshold.
- Tune sensitivity — Low, Medium, or High
- Pick your cue — 15 sounds, including a spoken "sit straight"
- Cool-down built in — no alert fatigue
- Private — nothing leaves your Mac
FAQ
How does Posturion know when I slouch?
It measures forward head, shoulder tilt, and head tilt using Apple Vision and fires a nudge when values pass your threshold.
Can I control how sensitive it is?
Yes — Low / Medium / High sensitivity, so you can tune it to your baseline.
Will it keep pinging me while I read?
No. Alerts only trigger on actual drift and have a cool-down.
Is my video recorded?
Never — every frame is analyzed on-device and discarded immediately.
