Build any session

Presets, or build your own

Start from a Tempo preset for walking, running, HIIT, jump rope, abs, boxing, and more, or build your own from scratch. Set work, rest, warmup, cooldown, and repeat groups with labels and distance targets.

Go from a 30/30 jump rope round to a long run-walk session in a few taps. Duplicate, reorder, and repeat to get the rhythm right.

In the workout

Everything readable at a glance

A large, clear display shows the current interval, time left, elapsed time, and what is coming next. Audio cues, haptics, countdowns, and the Tempo jingle keep you on track while your music keeps playing.

Cues keep working in the background, so you can lock your phone or switch apps and still hear every transition.

Built for real training

Tempo respects that not every interval workout is a run. Use it for conditioning, circuits, outdoor walks, treadmill work, boxing rounds, or focused mobility.

  • Japanese interval walking built in: 3 minutes fast, 3 minutes easy, for 30 minutes.
  • Optional GPS for distance and pace tracking on outdoor sessions.
  • Optional Apple Health access for heart rate, calories, steps, and workout summaries.
  • Workout history with redo, splits, distance, calories, and steps.
  • Premium video mode records your session with a minimal front or back camera overlay.
  • Privacy first: your workout data is never sold or shared, and every permission is optional.

Set your tempo, start training.
