Stop staring at a stopwatch mid-burpee. This is a HIIT interval timer that calls every work and rest phase out loud, so you stay in the burn and just keep moving until the round is done. Most timers make you glance at the screen between rounds. This one runs the whole session for you: a full-screen ring flips from work-red to rest-teal while voice, beep and haptic cues fire on every phase change and final countdown. Train Tabata, EMOM, sprint ladders or a circuit you build yourself — tap start, follow the cues, empty the tank. WHAT YOU GET - A custom interval builder for work, rest, sets, rounds, warm-up and cooldown - Ready-made Tabata, EMOM, sprint ladder and fat-burn presets to start in one tap - Voice, beep and haptic cues on every phase change plus a 3-2-1 countdown - A full-screen color ring that shows work, rest and set breaks at a glance - Progress tracking with streaks, work minutes, rounds, charts and session history - A halfway voice cue and keep-screen-awake mode so you never lose your place PERFECT FOR - HIIT and Tabata fans who want max effort without watching a clock - Home and gym athletes running circuit, EMOM or AMRAP-style rounds - Runners and cyclists doing sprint intervals and work-to-rest ratios - Anyone building a consistent, short, high-intensity training habit WHY NOT JUST USE THE PHONE STOPWATCH A stopwatch makes you look, tap and count between every round — exactly when you should be moving.
