Longitudinal AI body tracking · Progress photos · Habits

The time-lapse of your body — on your phone.

Other AI tools give you one snapshot and move on. BodyLapse captures every week: a multi-angle AI body scan with a confidence range, a physique score, and the four habits that actually drive change. Stacked over months, that’s your transformation — measured, not guessed.

Your waist is down 0.8 cm this week on stable weight. Keep protein above 160g and add one Zone-2 walk before Sunday.

Why BodyLapse

A snapshot is not a transformation.

Most AI body tools take one photo, spit out a body-fat number, and call it a day. You’re left with a data point and no arc. BodyLapse is built the other way: every weekly check-in becomes a frame in your time-lapse, and the habits that got you there are tracked right next to it.

Single-snapshot AI tools

One photo, one number.

  • Upload → see a body-fat %. That’s the product.
  • No longitudinal view, no trend, no arc.
  • No habit tracking — the things that actually change your body.
  • Photos disappear after the scan; nothing stacks week over week.
  • No HealthKit integration, no weight-trend chart, no streaks.
BodyLapse

A frame per week. A story per quarter.

  • Multi-angle scan: front required, side / back / legs optional — the more you add, the tighter your range.
  • Confidence-aware body-fat range (e.g. 14–17%) instead of fake precision.
  • Physique Score 0–100 so progress is legible at a glance, week over week.
  • Regional heatmap silhouette — see where the change is actually happening.
  • Four habits tracked next to the scan. Your body responds to behavior, not numbers.
  • HealthKit-synced weight, cloud backup, and a shareable result card.

Think Strava for strength, Flo for your period, Oura for sleep — we’re that, for your physique. A single snapshot is the screenshot. BodyLapse is the movie.

A 5-step journey, not a 30-day crash.

Transformations take 12+ weeks. BodyLapse is built around the stack that has actually worked for thousands of users — not another gimmick.

Everything you need, nothing you don't.

No 20-tab dashboards. No gimmick workouts. Just the measurements and habits that actually drive body composition change.

AI body scans

Estimate body fat, muscle mass, and posture from a single photo using a vision-language model trained on labeled scans.

Progress photos

Standardized capture, automatic 4/8/12-week side-by-sides, and share cards that export clean.

Smart charts

Weight, body fat, waist, and measurements on a 7-day rolling average. The trend line, not the daily noise.

4-habit framework

Train, fuel, sleep, move. Four checkboxes per day — the load-bearing pillars behind every transformation.

AI weekly coach

Every Sunday the coach reviews your data and tells you what to adjust: protein, training volume, cardio, sleep.

Cloud sync (encrypted)

Progress syncs across devices, encrypted in transit and at rest. Delete your data with one tap at any time.

HealthKit integration

Pulls your weight, steps, and workouts from Apple Health automatically. Never log the same data twice.

Private by default

Photos stored encrypted. No plaintext access. No selling data. No third-party ad trackers. Ever.

Built by and for people who've actually transformed.

The AI coach caught that my protein was averaging 30g low and my waist wasn't moving because of it. Adjusted, and the next four scans were the biggest drop of my cut.
Marcus R. · Lost 24 lbs in 18 weeks
The scale moved maybe 2 lbs in 4 months. The side-by-side photos told a completely different story. I wouldn't have stayed consistent without the visual feedback.
Priya S. · Body recomp, -4% body fat
I've used MyFitnessPal, Macrofactor, Happy Scale, you name it. BodyLapse is the first tracker that actually shows me the trend instead of the noise.
