Know exactly what to lift next. Peak sets every target from your last workout, so each session moves you forward. Free, no account, no ads. Peak is a simple strength training log that tells you what to lift next. Log a workout set by set, and Peak works out your next targets from what you just did. Hit the top of your rep range and the weight goes up; otherwise the reps do. Progressive overload, without the spreadsheet. TRAIN WITH A PLAN • Build your workouts and put them on a routine: fixed weekdays or every few days, with the workouts rotating in order • Home shows today's workout, your week at a glance, and what is next on rest days • Every set shows last time's weight and reps next to today's target • Set your own overload rules for the whole app, one workout or a single movement • Notes for each movement: seat height, grip, how it felt last time • Forgot to start a workout? Log it afterwards, on any past day SEE YOUR PROGRESS • Volume, sets and targets hit for the last 4 weeks, 3 or 6 months, a year or all time • Every movement with its trend and a chart of its estimated one-rep max, weight, reps and volume, with your records • A calendar of every workout you have done APPLE HEALTH • Steps, water and an Energy Level built from your sleep, heart rate variability and resting heart rate • Finished workouts and water are saved to Apple Health • Everything still works without Health access ON YOUR IPHONE, NOT IN THE APP • Home Screen and Lock Screen widgets for steps, water, energy, today's workout and your week • A Live Activity with the current movement and the clock, in the Dynamic Island too • Log water from a widget, Control Center or Siri without opening the app • A morning reminder on workout days YOUR DATA STAYS YOURS • No account, no ads, no analytics, no tracking • Everything is stored on your iPhone • Import your history from Excel, CSV or JSON, and export it any time Peak is free and open source (MIT). Energy Level is an estimate to help you plan your training. It is not medical advice.
