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 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 deg+ = Healthy neck posture
• 40-49 deg = Mild forward head posture
• Below 40 deg = Severe tech neck (forward head posture)

Healthy adults average ~49 deg (Kinovea 2024). We lose about 1.6 deg of neck posture per decade.

============================ 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 ML tech behind Google's fitness apps - with 468-point face mesh tracking for clinical-grade accuracy.

============================ BUILT BY A DEVELOPER WHO LIVED IT

I built PostureLens after 10+ hours a day of coding wrecked my neck. I wanted a posture app that just worked - quietly, accurately, privately. So I built it.

============================ 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 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.

Your tech neck took years to form. Five minutes a day is how you turn it around.
