PostureLens: AI Posture Coach

YOU WON'T FEEL TECH NECK UNTIL IT HURTS. THIS SHOWS YOU FIRST. PostureLens is the AI posture coach that measures your forward head posture with your phone camera — in real-time, 100% on-device, no wearable needed. No sign-up. No account. No data ever leaves your phone. ━━━━━━━━━━━━━━━━━━━━ YOU'LL NEED A PHONE STAND ━━━━━━━━━━━━━━━━━━━━ This isn't a tip — it's how the app works. Fix your phone on a stand at desk height, facing you. It has to stay in one place for the whole session — that's what lets PostureLens detect the moment your posture slips. A phone stand, a laptop riser, a propped-up case: anything that holds it steady. Set it up once and you never think about it again. ━━━━━━━━━━━━━━━━━━━━ TECH NECK IS A SILENT EPIDEMIC ━━━━━━━━━━━━━━━━━━━━ Every inch your head tilts forward can add up to 10 pounds of load on your neck, and most desk workers spend 6+ hours a day there. The stiff neck in the morning. The tension by 3 PM. Shoulders like stone. You can't change what you can't see — so PostureLens shows you, using the measurement physical therapists work with: the Craniovertebral Angle (CVA). ━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━ 1. Start a 10-minute session 2. Work, study or browse as you normally would 3. PostureLens tracks your neck angle and nudges you when it slips 4. See exactly when your posture went, and by how much Your report shows your posture band, how much of the session you held it, the moments you caught yourself, and your progress across the month. ━━━━━━━━━━━━━━━━━━━━ CVA — WHAT THE NUMBER MEANS ━━━━━━━━━━━━━━━━━━━━ The angle used in physical therapy research to describe forward head posture: • 50°+ = Healthy • 40–49° = Mild • Below 40° = Significant forward head posture Healthy adults average around 49° (Kinovea, 2024), and we lose roughly 1.6° per decade — faster if you're on your phone all day. ━━━━━━━━━━━━━━━━━━━━ 100% PRIVATE, 100% ON-DEVICE ━━━━━━━━━━━━━━━━━━━━ Detection runs entirely on your device. Your camera feed never leaves your phone — no cloud uploads, no account.

Doctor visits cost hundreds, braces felt ridiculous, wearables died in a week. So I built the tool I wished existed when my tech neck was at its worst — quiet, accurate, private. CVA is estimated from a 468-point face mesh, with shoulder landmarks refining the result at an angle. References: Kinovea 2024; forward head posture assessments (MDPI, PMC).
