Weight Tracker
Log your weight and body fat, see trend charts over time, and track progress toward your goals. AI scans smart scale screenshots and auto-fills your data. Simple, private, and works on any device.
How it works
Log your weight
Enter your weight in pounds. Add body fat, muscle mass, or any other metric if you track them — or keep it simple with just weight.
See your trend
The trend chart updates automatically with every entry. Switch between 7-day, 30-day, 90-day, 1-year, or all-time views to see your progress.
Track your goals
Set a target weight and monitor your progress. Export your data to CSV anytime to share with a coach or healthcare provider.
More than just a weight log
Trend charts
Visual charts show your weight trend over any timeframe. See every reading, spot patterns, and stay motivated with clear progress visualization.
Smart scale scan
Screenshot your Renpho, Withings, Hume Health, or Eufy app and AI reads the numbers — weight, body fat, muscle mass, and more — then fills the form for you.
Body composition
Track body fat percentage, fat mass, muscle mass, visceral fat, and BMI alongside weight. Or start with just weight and add more metrics when ready.
CSV export
Export all your weight and body composition data to CSV with one click. Share with a coach, doctor, or import into another tool. No data lock-in.
Works on any device
Install on your phone home screen for a native app experience. Log your weight in seconds right after stepping on the scale.
Private & secure
Your weight data is stored in your own private database with per-user auth. Never shared unless you choose to share it. Export and delete anytime.
