A complete workout log: a program built for you, loads adjusted mid-session, strength muscle by muscle. AI assistant and body fat analysis as options. Ratio is a complete workout log, built for building muscle: programs, sessions, progress. The whole training side is free, with no limits and no crippled tier. YOUR PROGRAM, OR NOT • Build your program in a few questions: where you train, equipment, days, muscles. Ratio composes it, balances the volume per muscle group and fills it with your loads. • Or train freely: start a session whenever you want, pick exercises as you go, Ratio remembers everything. • Programs are included, for free: hypertrophy, full body, push pull legs, upper/lower. • Coming from another app? Import your history from Strong, Hevy or Workout Factor: your sessions, loads and records come with you. YOUR SESSIONS • Every kind of session, every format: rep targets, RIR, RPE or free. • Smart progression if you want it: Ratio picks your loads and adjusts your targets during the session. Otherwise, you decide. • Calculated warm-up, adjustable rest, swap an exercise when the machine is taken. • Timer and sets on the lock screen: log a set without reopening the app. • Offline: the session runs without network and syncs afterwards. YOUR PROGRESS • The history of all your sessions and your attendance, week after week. • Your loads and records per exercise, estimated 1RM included. • The volume of every muscle, set by set, to see what your program really trains. AS A BONUS • Strength standards: where you stand for your body weight. • The Ratio assistant, with Premium: it reads your sessions, records and program, and answers your questions. • AI body fat, as an option, the only paid part of Ratio: one front photo, abs braced, and a vision model estimates your body fat percentage, FFMI, lean and fat mass. History and side-by-side comparison of any two dates. Weight syncs from Apple Health when available.
