Stop fumbling with complicated timers and start your workout in seconds. Get clear interval cues, a big easy-to-read countdown, and a round timer that keeps pace without breaking your flow. Round Timer: HIIT & Tabata helps you start, run, and track interval workouts on iPhone. Built for people who want to drop the phone, glance once, and keep moving, this HIIT timer focuses on quick starts and clear feedback. The GO card always launches your most recent workout, so your usual Tabata timer or interval timer is never more than one tap away. When a workout is running, the Live Activity and Lock Screen card keep the current phase, time left, and controls in view, and you can pause, skip, or stop from there. If you train with music, voice cues speak over your audio and then your music returns to normal volume. That makes it handy for Tabata abs while watching TV, sprint repeats at the track, or boxing rounds in the gym. โ€ข Start your last workout instantly from the GO card on Quick Start. โ€ข Pick from built-in presets including Classic Tabata, Beginner HIIT, EMOM 10, AMRAP 20, Boxing Rounds, and Sprint Intervals. โ€ข Build custom workouts with your own work, rest, rounds, get ready, and cooldown times. โ€ข Choose a protocol like Tabata, HIIT, EMOM, AMRAP, Circuit, Rounds, Sprint, or Custom. โ€ข Add per-round labels so voice cues can say Burpees or Push-ups instead of a generic work prompt. โ€ข See a giant full-screen countdown with color changes for work, rest, prep, cooldown, and finish. โ€ข Keep the next step in view with the UP NEXT preview and the round counter. โ€ข Control a session with large Restart, Play or Pause, and Skip buttons. โ€ข Let a saved workout start a playlist from your music library automatically and stop it when the workout ends. โ€ข Keep cues going when the screen locks, with optional haptics on every phase change. โ€ข Check History for this week, total time, streak, and session details, then share or delete a session. โ€ข Start from Home Screen, Lock Screen, Control Center, or a shortcut for even faster access. It fits real training moments. Start Classic Tabata for a quick core set, throw together a Circuit for class, run EMOM 10 in a garage gym, use Sprint Intervals for repeats, or keep Boxing Rounds visible from across the room. If you want one clean workout record instead of a pile of tiny entries, Pro can save each completed session to Apple Health as a single workout. The free version lets you save up to 3 custom workouts. Pro removes that limit and adds Apple Health saving for completed sessions. Music access is only needed if you want to play a playlist from your library, and Health access is only needed if you choose to save workouts there. Pick a preset, tap GO, and turn your iPhone into a clear, dependable HIIT timer for Tabata, EMOM, AMRAP, boxing rounds, and more.
