BodyCheck

BodyCheck scans QR codes produced by gym body composition analyzers and displays your measurements in an easy-to-read format.

Features:
- Scan QR codes with your camera or import from saved images
- View weight, BMI, body fat %, skeletal muscle mass, body water, protein, BMR, biological age, and health score
- See lean and fat mass distribution across body segments (arms, trunk, legs)
- Track your body composition history over time
- Export and import your data for backup or device transfers
- Completely offline -- no internet connection required

The app reads QR codes containing body composition data as a JSON array of numeric measurements. It supports arrays of 63, 64, or 95 values and validates that key metrics fall within physiologically plausible ranges.

All data is stored locally on your device. No data is ever sent to any server. No analytics or tracking.
