HIITime

HIITime began as a HIIT timer and grew into the only workout app you need. High-intensity intervals, strength training and cardio now live together on iPhone and Apple Watch — fast, native, and saved straight to Apple Health.

INTERVAL & HIIT TIMER
• Build routines with work, rest and recovery phases, plus warm-up and cool-down
• A full-screen countdown you can read across the room
• Spoken cues, countdown beeps and interval chimes call every phase, so you never look down
• Circuit mode links real library exercises into timed stations

STRENGTH TRAINING
• Reusable templates with supersets, target sets, reps and rest
• Log sets live — weight, reps and automatic rest timers
• Personal records detected and celebrated the moment you hit them
• Estimated 1-rep-max using Epley, Brzycki or Lombardi

CARDIO
• Track runs, cycling and functional cardio live, or log them by hand
• Distance, time, heart rate and calories, all saved to Apple Health

870+ EXERCISE LIBRARY
• Every move with muscle groups, equipment and instructions
• Search and filter by muscle or gear, and save your favourites
• Add custom exercises and build your own variants

BUILD WORKOUTS WITH AI
• Copy a ready-made prompt into ChatGPT or Claude, then paste the result to import a full workout
• Or share workout text from any app straight into HIITime
• Nothing leaves your device — the app does no AI calls of its own

APPLE WATCH
• Start and follow HIIT workouts on your wrist
• Log strength sets with the Digital Crown, with haptics between sets
• Live heart rate the whole way through

APPLE HEALTH & HEART-RATE ZONES
• Workouts, heart rate and active calories written to Health
• Zones that match Apple Watch (Heart Rate Reserve), or switch to % of max HR

STATS & HISTORY
• One timeline across HIIT, strength and cardio
• Streaks, training volume, 1-rep-max trends and full PR history

LIVE ACTIVITIES
• Follow your HIIT workout from the Lock Screen and Dynamic Island

MADE YOURS
