Tired of tapping through menus before a run? Interval Running is a simple HIIT, tabata, and interval timer - say what you want, it builds the intervals, you run. Just tell it what you want. Say something like "eight rounds, 30 seconds fast, 30 seconds easy" and the timer builds your program right then - no forms, no menus, no fields to fill in before you can start running. Prefer to build it yourself? You can: - Set work and rest by time, distance, or leave it open - Choose HIIT, tabata, fartlek, tempo, or plain run/walk intervals - Save a routine once, reuse it whenever you want Everything you need is on the screen while you run, no extra taps. - Interval, pace, cadence, and heart rate at a glance - Audio cues tell you when to switch, no need to look down - Full Apple Watch support - leave your phone at home You don't want a training plan, a coach, or a program - you want a timer that starts and stops intervals exactly when you tell it to. You want to set up a workout on the way to the track without stopping to tap through screens. You do tabata or HIIT sessions and just need something that counts rounds. You run intervals on your own terms and don't want an app deciding your pace for you. After each run, see your intervals, pace, and heart rate. Export GPX files, sync with Apple Health, and connect an external heart rate monitor if you use one. Health app integration With your permission, your interval runs count toward Activity Rings, including the Exercise and Move rings. Say it. Start it. Run.

Every run deserves to be remembered — and to be seen. Cadence tracks every mile with precision, then cuts it into a beat-synced film and a share card your friends will want to like — in one tap. CAPTURE ON THE RUN Tap the camera mid-run for photos and video — beauty, starburst, light trails and every scene preset included. Launch it from the Lock Screen, Dynamic Island, Control Center or the Action button, or ask Siri; the volume buttons work as the shutter. Mid-run captures become your film when you finish, with the distance, pace, heart rate and time of that exact second overlaid. ONE-TAP FILMS, ON THE BEAT Turn photos, clips and an animated route map into a film in one tap — every cut lands right on the music. Fine-tune with transitions, filters, picture-in-picture, text, effects and speed control, and drop a spinning medal into the frame. SHARE CARDS THAT STAND OUT Neon spectrum routes, stat stickers, fonts and colors. Drag, scale and rotate anything, or export a transparent sticker to layer on any photo. Share cards are free, forever. HIDDEN SURPRISES Hit a lucky distance, set a record or run on a holiday to unlock a gold, silver or bronze keepsake medal. Flick to spin it 360° and find the date, pace and time engraved on the back. Every medal lives on your Medal Board. SERIOUS TRACKING - Running, hiking, mountaineering and indoor (treadmill) modes - GPS route, distance, time, pace, elevation, grade, climb rate and calories - Indoor runs via the step counter — no GPS needed, with real per-km splits - Cadence metronome (140–200 spm) that keeps ticking on the Lock Screen over your music - Lock Screen Live Activity and Dynamic Island - Optional Apple Health sync PRIVACY No account required. Workouts stay on your device unless you choose to sync with Apple Health. Photos and camera are used only to pick or shoot share media; location only to record outdoor routes.
