What is Workout Timer?

Workout Timer lets you create custom interval training sessions with configurable work and rest periods. Set up rounds with different durations for exercises, rest breaks, and cool-downs — perfect for HIIT, circuit training, or any timed workout routine.

How to use

1. Set your work interval duration (e.g., 30 seconds) and rest interval duration (e.g., 10 seconds).
2. Choose the number of rounds you want to complete and optionally add a warm-up or cool-down period.
3. Press Start to begin — audio cues and visual indicators will guide you through each interval transition.

Result

A typical HIIT session: 30s work / 15s rest × 8 rounds with 10s prep countdown. Total workout time: 6 minutes 10 seconds of intense interval training.
