OnPeak is a body composition and nutrition tracking app for people who train seriously.

Measure your body fat percentage with a skinfold caliper and set your macros for the phase you are actually in: cutting or bulking. No generic estimates: real measurements, real progress.

You need a skinfold caliper to measure your body fat. It is an affordable accessory and easy to find.

HOW DO YOU MEASURE BODY FAT WITH A CALIPER?
- Jackson-Pollock 7-site skinfold protocol, the standard used in physique prep
- Enter each skinfold and get your body fat percentage instantly
- Illustrated guide for every site: where to pinch and in which direction, so your measurements stay comparable

- Fat mass and lean mass calculated for every measurement
- Charts of body fat, weight and skinfolds over time
