PostureLens: AI Posture Coach

FIX YOUR TECH NECK BEFORE IT FIXES YOU.

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.

━━━━━━━━━━━━━━━━━━━━
TECH NECK IS A SILENT EPIDEMIC
━━━━━━━━━━━━━━━━━━━━

Every inch your head tilts forward adds 10 pounds of pressure to your spine.
Most desk workers and heavy phone users spend 6+ hours a day in forward-head posture.

That's why you wake up with a stiff neck.
That's why headaches hit you by 3 PM.
That's why your shoulders feel like stone.

PostureLens gives you the same measurement physical therapists use — the Craniovertebral Angle (CVA) — in a simple, one-tap posture app.

━━━━━━━━━━━━━━━━━━━━
HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━

1. Place your phone on your desk
2. Start a 5-minute posture session
3. Work, study, or browse like you normally would
4. PostureLens measures your neck angle 30 times per second
5. See exactly when your posture slipped — and by how much

Your session report shows your average CVA, time spent in good vs. bad posture, a bad-posture breakdown, and your progress over time.

━━━━━━━━━━━━━━━━━━━━
CVA — THE POSTURE GOLD STANDARD
━━━━━━━━━━━━━━━━━━━━

CVA is the clinical standard used in physical therapy research:
• 50°+ = Healthy neck posture
• 40–49° = Mild forward head posture
• Below 40° = Severe tech neck (forward head posture)

Healthy adults average ~49° (Kinovea 2024). We lose about 1.6° of neck posture per decade — longer if you're on your phone all day.

━━━━━━━━━━━━━━━━━━━━
100% PRIVATE, 100% ON-DEVICE
━━━━━━━━━━━━━━━━━━━━

All AI posture detection happens on your device.
Your camera feed never leaves your phone.
No cloud uploads. No account required.

Powered by MediaPipe — the same on-device machine learning tech behind Google's fitness apps — combined with 468-point face mesh tracking for clinical-grade accuracy.

BUILT BY A DEVELOPER WHO LIVED IT
━━━━━━━━━━━━━━━━━━━━

I built PostureLens because I spent 10+ hours a day coding, and my neck paid the price. Doctor visits cost hundreds. Posture braces felt ridiculous. Wearables died in a week.

I wanted a posture app that just worked — quietly, accurately, privately. So I built it.

This is the tool I wished existed when my tech neck was at its worst.

━━━━━━━━━━━━━━━━━━━━
WHO POSTURELENS IS FOR
━━━━━━━━━━━━━━━━━━━━

• Developers, designers, writers — anyone at a desk 6+ hours a day
• Remote workers whose posture has quietly gotten worse
• Students during long study sessions
• Heavy phone and tablet users fighting tech neck
• Anyone waking up with neck pain or tension headaches

━━━━━━━━━━━━━━━━━━━━
THE SCIENCE BEHIND IT
━━━━━━━━━━━━━━━━━━━━

PostureLens measures CVA using two AI models working together:
• Face Mesh (468 landmarks) — precise front-view posture detection
• BlazePose (33 keypoints, 3D) — side-view clinical accuracy

References:
• Kinovea 2024: CVA reference values
• Forward head posture assessments (MDPI, PMC)

PostureLens is a posture awareness tool, not a medical device.
