HIITime

Built for athletes who take their intervals seriously. Custom routines, real-time heart rate zones, Apple Watch, voice cues, and full workout history.

HIITime is powerful HIIT interval timer for iPhone and Apple Watch. Build custom routines, track your heart rate live, and get voice-guided audio cues through every phase.

YOUR WORKOUT, YOUR WAY Create unlimited routines with custom interval groups, set repeat counts, and dial in every work and rest duration to the second. Add warmup and cooldown phases for a complete session - exactly the way you train.

LIVE HEART RATE & APPLE HEALTH See your heart rate zone in real-time as you push. HIITime integrates with HealthKit to track heart rate, active calories, and saves every session to Apple Health automatically.

NEVER LOSE YOUR PLACE An animated countdown ring shows exactly how much time remains in each phase. Voice announcements call your next phase and duration. Countdown beeps and interval chimes keep you locked in - even when your screen is dark.

APPLE WATCH COMPANION Run sessions from your wrist. The Apple Watch app mirrors your iPhone workout with a live countdown ring and on-wrist heart rate tracking - no phone required mid-session.

COMPLETE WORKOUT HISTORY Every session is saved with a detailed breakdown: heart rate chart with phase bands, per-interval average HR, active calories, total duration, and intervals completed. Your training history, always at hand.

DESIGNED FOR EVERY ATHLETE Whether you're following a Tabata protocol, running CrossFit WODs, building your own AMRAP circuits, or just starting your fitness journey — HIITime has the tools to match your training.
