HIIT/Tabata Timer

What is HIIT/Tabata Timer?

Set work and rest intervals, pick your rounds, and go. The timer counts down each phase with audio beeps and tracks your rounds and total time.

How to use

1. Step 1 — Set your work interval (e.g., 20 seconds), rest interval (e.g., 10 seconds), and number of rounds (e.g., 8 for classic Tabata).
2. Step 2 — Press Start. The timer alternates between work (highlighted in green) and rest (highlighted in blue) with audio beeps at each transition.
3. Step 3 — Track completed rounds and total elapsed time. Pause anytime to catch your breath or adjust settings for the next set.

Result

Classic Tabata: 20s work / 10s rest / 8 rounds = 4 minutes total. The timer beeps three times before each transition and shows a large countdown with your current round.
