How Peak Fettle compares
Free-tier limits, where your data is kept, and whether the app ranks your strength, for the trackers people usually compare.
Where Peak Fettle differs
- Data on your phone
- On the free plan your workout log is stored on your iPhone and works offline. There are no caps on logging, routines or history. Pro also keeps the log on our server so it follows you to a new phone.
- Exact entry
- Type 186.7 and 186.7 is what is stored, in the unit you typed. Weights are not rounded to the nearest plate or bent by a unit conversion.
- Strength percentiles
- Percentiles on 51 lifts, calibrated to published strength standards and adjusted for sex, bodyweight, age and years trained. They are worked out on your phone, not against a pool of other users.
Workout trackers
Boostcamp has far more ready-made programs and Fitbod adjusts workouts for you. Peak Fettle is the one that ranks your strength and keeps the whole log free.
