# Mounjaro progress tracker

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

Track Mounjaro or Zepbound progress the way that shows what the scale can’t: photos, waist, and whether you’re keeping muscle.

Short answer

To track Mounjaro or Zepbound progress, log weight and waist weekly, measure arms and shoulders to catch muscle loss, and take matched photos every two weeks. ProgressLens does all of this on iPhone and Android, and its AI Progress Report flags if you’re losing muscle as well as fat. Keep doses in your clinic’s app.

**Not medical advice.** GLP-1 medications are prescribed and supervised by a clinician. This page explains published trial results and how to track your own body; talk to your prescriber about your dose, protein and training.

## What a Mounjaro progress tracker should track

- Weight, weekly or as a weekly average.
- Waist, the best single sign of fat loss.
- Arms and shoulders, to catch muscle loss.
- Matched photos, front and side, every two weeks.
- Doses and side effects, in your clinic’s app or a dose tracker.

## How ProgressLens tracks Mounjaro and Zepbound progress

ProgressLens keeps weekly check-ins: photos lined up with a ghost overlay of your last one, plus weight, waist, chest, shoulders, arms and thighs. Tell it in About you that you’re on a GLP-1, and AI Analyze tailors the Progress Report: your body-fat range, what changed, a muscle-loss signal (if arms and shoulders drop as fast as your waist), and a weekly rate. It doesn’t log doses; keep those in your clinic’s app.

### Track Mounjaro progress.

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.

## Mounjaro progress chart: reading your trend

Charts of weight jump around week to week. Read the four-week trend of your waist instead, and set it against your arms. Waist down and arms steady: fat loss. Both down fast: talk to your clinician about protein and training. See [GLP-1 progress month by month](https://progresslens.app/guides/glp-1-progress-month-by-month/).

## Private by default

Photos stay in the app on your phone, not your camera roll or a cloud, and there’s no account. Photos you analyze are sent to the AI and aren’t stored or used for training.
