The bar doesn't tell the whole story. You can add plates to your lifts for months without seeing what's actually changing: an arm gaining a centimeter, a waist getting leaner, body fat trending down. That's why Musku now tracks your body measurements, right inside the app.

## Twelve measurements, log what you want

Weight, body fat, shoulders, chest, left and right arm, waist, hips, thighs and calves: you only fill in what you actually measured, at your own pace. A daily weigh-in, a monthly arm measurement, or everything at once after your Sunday measuring session. Your call.

## A chart for every measurement

Each measurement gets its own page: latest value, change over the period, progress chart and full history. You can fix a value or a date after the fact, and delete a wrong entry. Weight is tied to your profile: your latest weigh-in automatically becomes your current weight, the one used by the AI analysis.

## Apple Health sync, both ways

Weight, body fat and waist circumference sync with Apple Health:

- **Musku to Health**: every entry shows up in the Health app, next to your other data.
- **Health to Musku**: a weigh-in on a connected scale (Withings, Eufy...) automatically lands in Musku.

One simple rule protects your data: anything you type in Musku yourself is never overwritten by the import. And Musku never touches data written by other apps in Health.

## How to enable it

Entry lives in **Profile → Measurements**. For the Apple Health sync, head to **Settings → Measurements in Apple Health**: iOS will ask for read and write permissions, which you can adjust per measurement.

Measurement tracking is free for everyone. [Download Musku on the App Store](https://apps.apple.com/app/musku/id6766680804) and start tracking more than the bar.
