# ProgressLens vs bodyfatAI

By the [ProgressLens team](https://progresslens.app/about/) · Updated November 13, 2026

A one-off scan or rating, or a running read of your own progress? Here’s how they differ.

Short answer

bodyfatAI multi-photo AI body fat scans with monthly muscle analytics and a leaderboard. ProgressLens is an AI progress photo app for iPhone and Android: it reads your photos together with your tape measurements, so its body-fat range stays steady, and every Progress Report says what changed, whether you’re losing fat or muscle, and whether to cut, lean bulk, recomp or maintain. Pick bodyfatAI for multi-photo AI body fat estimates with monthly analytics; pick ProgressLens to track whether it’s working and what to do next, on any phone, in 11 languages.

**Disclosure:** we make ProgressLens. Details about other apps come from their own store listings and websites as of November 2026; prices and features change, so check the listing before you pay. We name each app’s weaknesses and our own.

## Choose bodyfatAI if…

you want multi-photo AI body fat estimates with monthly analytics.

## Choose ProgressLens if…

you want to know whether your progress is working and what to do next: a steady body-fat range from photos plus tape, what changed since last time, a fat vs muscle check, and a clear cut or bulk verdict, on iPhone or Android, in your language, without an account.

## Why photos plus tape beat a single scan

Photo-based body fat estimates move with lighting, pump, pose and clothing, so two scans a week apart can disagree by several points. In our [analysis of Reddit posts](https://progresslens.app/research/what-lifters-ask-about-body-fat/), people quoting estimates from different AIs saw gaps of 2 to 8 points. ProgressLens anchors the photo read with the US Navy tape formula and your history, and the same photos always give the same result.
