Custom interval timer
Set your own effort and recovery times and the number of rounds, and the timer handles the rest. Voice cues, beeps and a big round display make it easy to follow on a treadmill.

Why it works
Choose times that match your plan, whether from a coach, a training program or your own experiments. Everything else works the same as the built-in workouts.
Who it's for
Anyone following a specific training plan, or who has outgrown the presets.
Questions
Does it work on my phone?
Yes. Add HIIT Count to your home screen for one-tap access, and the screen stays awake during your workout.
Do I need an account?
No. Accounts are optional and only needed to save your history, streaks and personal bests.
Is it free?
Yes. The timer, coach and every workout type are free.
Warm up with 5 minutes of easy walking or jogging first. Stop if you feel dizzy, faint or unwell. If you have a health condition, check with a doctor before starting hard exercise.
