# ProgressLens vs trackBod

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

trackBod a front-and-side photo scan that estimates body fat and rates muscle groups. 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 trackBod for a quick body fat and muscle rating from two photos on iPhone; 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 trackBod if…

you want a quick body fat and muscle rating from two photos on iPhone.

## 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.

## See how far you’ve come.

Take a check-in, tap AI Analyze and get your Progress Report: body-fat range, what changed, fat or muscle, and whether to cut or bulk. On iPhone, iPad and Android, with no account. Your photos stay on your phone.

FAQ

## Frequently asked questions

**Is there an Android alternative?**

Yes. ProgressLens runs on Android and iPhone with the same AI Progress Report on both.

**Does ProgressLens rate muscle groups like trackBod?**

No. It tells you what changed area by area and whether you’re losing fat or muscle, rather than scoring each muscle.
