HIITCounter

HIIT Counter is a glanceable interval timer for workouts where you want to focus on movement, not the screen.

BUILD YOUR WORKOUT
• Set Train and Rest times from 5 seconds to 5 minutes
• Choose sets per exercise and number of exercises
• See the total workout time before you start
• One-tap Tabata (20 s on, 10 s off, 8 rounds)
• Save your own presets and reuse them any time
• Chain presets into a workout plan, such as Plank, then Sit-ups, then Bench Press, with each exercise's rest kept between steps

STAY IN THE ZONE
• Big, color-coded countdown ring: green to train, red to rest
• Sounds, spoken coach cues and haptics for every segment change
• Encouragement during Train: "Push!" and "Almost there!" on longer intervals
• Breathing guide on rest: paced 3-second in, 5-second out cues with a longer exhale for recovery, repeated on longer rests
• My Voice: record the spoken cues in your own voice, or import audio you made elsewhere, such as an AI voice
• Spoken cues start just before each interval so "Go!" lands exactly as the timer does
• Cues mix over your music and work with the Silent switch
• Live Activities keep the current interval on your Lock Screen and Dynamic Island
• Pause or resume at any time; ending early asks whether to save the workout or discard it
• The screen stays awake during a workout

TRACK YOUR PROGRESS
• History of every workout with weekly and monthly totals
• Daily streaks to keep you consistent
• Live heart rate on the workout screen when Apple Health has a recent reading, such as from an Apple Watch workout (optional)
• Optionally save finished workouts to Apple Health, with estimated active energy based on your weight in Health (including Withings scales)

SIRI AND SHORTCUTS
Start a saved preset or a custom workout by voice or from Shortcuts.

PRIVATE BY DESIGN
No account, no ads and no tracking. Your workouts stay on your device. Apple Health access is optional.

OPTIONAL AI WORKOUT DESIGNER
On devices with Apple Intelligence, describe the workout you want, such as "15 minutes, no equipment, beginner", and HIIT Counter drafts an interval plan using Apple's on-device model. Everything else in the app works without it.

Perfect for HIIT, Tabata, circuit training, boxing rounds, home workouts and gym sessions.
