Navy Body Fat Percentage Calcu

Fairly accurate body fat percentage calculator. All you need is a tape measure!

Now in Beta, the Navy Body Fat Percentage Calculator app helps you easily plug your body circumference measurements into the formula commonly known as the 'Navy method', long used by the US Navy as part of its fitness readiness test (FRT) and body composition assessment (BCA).

All you need is a tape measure, and the circumference reading of two (or three) sites in your body: your neck and your waist, and also your hips, if you're a woman.

Track your weight and body composition changes in a colorful graph that shows you how your lean mass and fat mass have changed over time.

Give it a try! This is a simple Beta release, but a lot of features are in the pipeline, and with your valuable feedback we can prioritize those features that you want the most.

While not one of the most accurate methods of measuring body fat (it is an estimate, after all) it is in close agreement with sophisticated body composition analysis methods. Check out the Help section of the app for the juicy references to the original research papers!
