OnTrack

Built for the minute between sets

Everything you need mid-workout is one tap away. Everything else stays out of the way until you want it.

  • Log fast

    Tap to complete a set. New sets fill in from the last time you did that exercise, so you rarely type. Track weight and reps, time or distance, with warm-up sets and notes.

  • Plan ahead

    Build templates like Push Day or Leg Day. Starting one sets up every set at your planned weight and reps. Put templates on a weekly routine or on specific dates.

  • Circuits and timers

    Quick HIIT rounds with work and rest cues that keep going with the screen off, plus a stopwatch and countdown.

  • See your progress

    Personal records are detected automatically. Lifetime totals, your top exercises and every workout on a calendar show how far you've come.

  • Live heart rate

    Record heart rate during workouts and circuits from your watch, earbuds or a chest strap, then see it graphed for each workout.

  • Apple Health and Health Connect

    Save workouts and measurements to Apple Health on iPhone or Health Connect on Android, and bring in weight and body fat from your other apps.
