Peak: Workout Log

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
