OnPeak: Body Fat Tracker

OnPeak is a body composition and diet app for people who train seriously. No bioimpedance scale, no generic calorie estimates. OnPeak measures your body composition with skinfold calipers (Jackson-Pollock 7-site protocol) and adjusts your diet directly from that real measurement, not a generic formula. You need skinfold calipers to use OnPeak: every entry logs weight and skinfolds together. It's a cheap, easy-to-find accessory. SKINFOLD BODY FAT - Jackson-Pollock 7-site protocol: chest, abdomen, thigh, triceps, subscapular, suprailiac and midaxillary - Multiple readings per site with automatic averaging, to cut down measurement error - Site-by-site visual guide: where and how to take each skinfold - Calculates body density, body fat % (Siri equation), fat mass and lean mass, with separate formulas for men and women TRACKING AND CHARTS - Weight, fat mass and lean mass over time - Full history of every measurement - Goal roadmap: expected progress band week by week compared against your actual measurements - Automatic alerts when the trend shows lean mass loss or excess fat gain, with a suggestion to adjust calories or move your target date MACROS WITH ON AND OFF DAYS - Cutting and Bulking phases - Calories and macros per kg of body weight, different for ON (training) and OFF (rest) days - Optional target body fat % or lean mass, with a date - Macro adjustments tied to your real progress, not a fixed calculator WHO ONPEAK IS FOR Gym, strength training, bodybuilding, and competitive or recreational physique athletes. For anyone who wants lab-grade precision in their body tracking instead of a bioimpedance scale, and a diet that adjusts to their own progress. 14-DAY FREE TRIAL Try OnPeak free for 14 days with every feature unlocked.
