The ultimate Tabata and HIIT timer, built for simplicity and precision. Train on iPhone, iPad, or Apple Watch, or use iPhone and Watch together. You get a clean, focused workout that fits whatever device you're using. Highlights: • Customizable intervals: Set get-ready, work, rest, and rest between cycles, with up to 20 rounds and 20 cycles. Work and rest periods can each run from 5 seconds to 10 minutes. • Large, easy-to-read timer: A bold, high-contrast display with big stats you can read in the middle of a hard set. • Live heart rate: See your heart rate during the workout, with a beating heart icon, on both Apple Watch and iPhone. • iPhone and Apple Watch, in sync: Start a workout on either device and the other follows along. Your settings stay matched between workouts too. • Standalone Apple Watch app: Leave your phone behind and run full workouts from your wrist. • Saves to Apple Health: Workouts are logged as High Intensity Interval Training, with heart rate and active energy, so they count toward your Activity rings. • Quick adjustments: Turn the Digital Crown or tap +/− to change settings. The Watch uses bigger steps for longer durations, so you can set them in fewer turns. • Layouts for every device: Designed for iPhone (portrait and landscape), iPad, and Apple Watch. • Audio and haptic cues: Countdown beeps and vibrations keep you on pace without looking at the screen. Built for athletes, trainers, and anyone who wants to stay focused on the workout, not on complicated settings.
