A range, not a fake number.
Take a guided photo scan and LeanScan gives you a body-fat range and a confidence band — never a falsely precise single number.
A photo can’t promise a decimal. Most apps pretend it can.
Body-fat-from-a-photo has a real margin of error — typically ±4-5 percentage points. LeanScan shows that margin openly instead of dressing up a guess as a measurement.
One confident digit, no error bar, no hint that a single photo carries real uncertainty — so you trust a number that was never that exact to begin with.
A range and a shaded band around it, every single time — so what you see on screen matches what the estimate can actually support.
Three steps. No false certainty at any of them.
Guided capture
A live framing overlay tells you exactly how to stand and when the shot is clean, before it ever gets sent.
AI estimate, with error bars
Our processing provider returns a body-fat estimate and its own margin of error — not a single silent guess.
A range you can act on
You see a range, a shaded band, and a trend line that narrows as more scans build confidence over time.
The trend line is a band, not a thread.
Your trend line comes with its own shaded margin of error, shown honestly instead of hidden.
A guided capture. An honest comparison.
A live framing overlay and real-time tips help you get the angle right before you capture.
Compare any two scans side by side, then export a branded share card.
Some days, skip the digit entirely.
Hide the exact percentage everywhere and track only the trend shape and photos.

Sent once. Deleted right after.
Your photo goes to our AI processing provider once for the estimate and is deleted from our servers immediately after — we do not store it and do not use it to train AI models.
Captured photos are also kept encrypted on your device for the before/after comparison; backups you export do not include photos, only scan history and settings.
Built for people tired of fake certainty.
Every other scale-app I’ve used swore it knew my body fat to the decimal. LeanScan is the first one that admitted it doesn’t — and I trust the range more than I ever trusted their fake number.
I turned Numbers Off after week two. Watching the band narrow and the line drift down did more for me than any digit could.
The before/after slider is brutal in a good way. No filter, no fake precision — just two honest scans side by side.
