The interval timer you don't have to look at. RoundShift calls out every round — get ready, work, rest, half way, last round — so your eyes stay on the workout, not the screen. BUILT IN SECONDS • Tabata, HIIT, EMOM, strength presets — or design your own • Warm-up, custom intervals, unlimited rounds • Describe a workout in plain words and let RoundShift build it VOICE THAT COACHES • Real coach voices in 10 languages — or calm and hype styles • 89 exercise names spoken aloud in custom workouts • Works with the screen off, phone face down, music playing COACH MODE ON THE BIG SCREEN • AirPlay the countdown to any TV for group sessions and classes • Giant display the whole room can read APPLE WATCH + ADAPTIVE REST (PRO) • Full timer on your wrist with live heart rate • Rest that adapts: end rest early when your heart rate recovers, or extend it when you need more • Workouts logged to Apple Health with the right activity type SEE YOURSELF SHOW UP • Streaks, weekly minutes, and a calendar of every session • Home Screen widgets and quick actions NOT JUST FOR THE GYM • Box breathing and breathwork: 4-4-4-4 in seconds • Stretch and physio holds with spoken changeovers • Focus sprints for study and deep work • Anything that repeats: intervals are intervals RoundShift is free forever for running timers and built-in workouts.
