Posture Science

SitSense used to grade your posture out of 100, rank you against strangers, and email you when your streak died. 84% of people never came back for a second day. Here is what we built instead, and why.

We measured 104,373 real posture readings from 205 people on webcam AI. Poor posture more than quadruples after 30 minutes of sitting (12.7% → 52.4%), good posture holds only 34.9% of the time, and uneven shoulders — not tech neck — is the #1 flagged problem. Full first-party data, methodology, and a downloadable dataset.

An hour-by-hour breakdown of what 8+ hours of daily sitting does to your posture, metabolism, back, and focus — and the research on how much movement it takes to undo it.

Research-backed posture correction timelines by condition. Forward head posture: 4-6 weeks. Rounded shoulders: 8-16 weeks. Real studies, habit science, and SitSense user data.
