Pinchpoint

Pinchpoint estimates your body fat percentage from a single belly photo.

Open the app. Tap. Take one photo. See your number. That's the whole product.


WHY ONE PHOTO
Calipers are awkward and inconsistent. DEXA scans cost $50+ and need an appointment. Smart scales drift week to week. Pinchpoint gives you a directional read in 5 seconds — useful for tracking, not for medical decisions.


HOW IT WORKS
A multimodal AI model analyzes your photo: visible abdominal definition, V-cut, fat fold over the navel, lat-to-waist taper. It returns a calibrated estimate (3%–60%), a classification (Athletic, Fit, Average, Above avg, High), and a confidence score.

If it can't read the photo cleanly — bad lighting, clothing in the way, not a body shot — it tells you so honestly instead of inventing a number.


WHAT'S TRACKED
• Estimate over time, on a clean trend chart
• Optional weight (so you also see fat mass and lean mass)
• A history grid to compare today's read to last month's
• Before/after slider when you have two saved entries


PRIVACY — THIS IS THE WHOLE POINT
• No account. No email. No cloud sync.
• No analytics, no ad SDKs, no third-party trackers.
• Photos and history live on this device.
• A random 256-bit ID is generated at install — that's the only identifier the analysis backend ever sees, and it can't be linked to you.
• Tap "Erase All" in Settings and the server-side row + any cached photos are deleted; the device ID rotates so the next session is a brand-new identity.


NOT MEDICAL ADVICE
Pinchpoint produces estimates. Body fat measurement is an estimation problem at every level — DEXA, BodPod, and hydrostatic weighing all disagree with each other. Use this for trends, not absolute values. If you have a clinical reason to know your body composition precisely, see a doctor.
