About this app
Two doors: get your heart rate up, or loosen off. HIIT, Tabata and circuits on one side; stretching, mobility and posture work on the other. Paste a YouTube video or Shorts and it becomes a timed workout. Or tell AI Coach what you want — out loud, if your hands are busy — and get a ready-to-run circuit in seconds. Zestimer calls every switch, work, rest, round, with voice and haptics, so you can just move. On iPhone and Apple Watch. FROM A VIDEO TO A WORKOUT Paste a YouTube link — a full class or a 30-second Shorts — and Zestimer lays it out as a timed workout you can run. Search YouTube without leaving the app, or copy a link anywhere and Zestimer offers to convert it the moment you come back. Every workout keeps a credit to the original video and channel. STRETCH, AND UNDO THE DESK Twelve stretch routines, timed and called the same way. Desk relief for a stiff neck and shoulders, a hip routine for anterior pelvic tilt, warm-ups before and cool-downs after, and a four-minute daily loosen-off. Every hold is announced — including the switch to the other side, so you stop guessing. A TIMER YOU CAN FEEL A big glass dial counts every interval with color, sound, and haptics — orange for work, green for rest. Play your favorite music from Spotify or Apple Music while Zestimer keeps your workout on track. Your screen stays awake, and one long press ends the session. COACHED BY AI Tell AI Coach what you want to train — type it, or just say it out loud — and get a ready-to-run workout. Already have one? Describe the change in a sentence and AI edits it in place: swap a move, shorten the rest, add a round. No starting from scratch. BUILD IN SECONDS Assemble circuits with rounds, work and rest times, and 118 illustrated moves — every one of them equipment-free. Reorder with a drag, edit every timing in one sheet, and favorite the workouts you repeat. ON YOUR WRIST, ON YOUR TV Run the whole workout from Apple Watch, with taps you feel through every switch. Or connect a TV or external display and the current move fills the screen, big enough to read from across the room — your phone stays the remote. STAY ON A ROLL Streaks with earned freezes, weekly goals, lifetime stats, and Home Screen widgets keep your momentum visible — and a share card makes your progress story-ready for Instagram. TWENTY-FOUR, READY TO RUN Twelve workouts behind each door. HIIT from a seven-minute classic to Tabata and boxing rounds; Stretch from a morning loosen-off to post-leg-day recovery. We don't track any data. Your workouts sync privately through iCloud. Zestimer Pro unlocks unlimited workouts and full AI coaching.
