HIIT Workout Timer vs RoundFlow

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. This timer runs the full circuit hands-free with audio and haptic cues, so you keep your eyes off the screen and your effort where it belongs. PRIVACY Everything runs on-device. No account, no ads, no tracking — your workouts and stats never leave your phone, and the whole app works fully offline. FULL ACCESS A membership unlocks unlimited custom circuits, the full interval builder, and complete progress tracking (streaks, charts and session history). It is offered as a weekly plan, a yearly plan, or a one-time lifetime purchase. Lace up, tap start, and let the timer run your workout.

RoundFlow is the round timer you can pay for once and keep forever, and it doesn't kill your music. It keeps timing with the screen locked, ducks your music for the bell, then hands the volume straight back. Start Spotify, Apple Music or YouTube Music, hit START, lock the phone and train. Your playlist never stops.
