Interval-Workout-Timer

The interval timer that never lets you down. Built for HIIT, Tabata, boxing, and CrossFit - set your intervals, press start, train.

SET YOUR WORKOUT
Work duration, rest duration, and rounds. Quick-access buttons let you jump to common settings instantly. Build structured workout programs with multiple exercises, each with its own timing and rest period.

TIMER MODES
The standard interval mode is free. Pro adds EMOM (every minute on the minute), AMRAP (as many rounds as possible), For Time, and Pyramid. Each mode has its own controls and post-workout stats.

ALWAYS RELIABLE
Reliable timers that keep running in the background, on the Lock Screen, in Silent mode, and during Focus. Beeps and haptics fire on every transition, every time.

LIVE ACTIVITY & DYNAMIC ISLAND
A live countdown on your Lock Screen - no need to unlock mid-workout. Tap the Dynamic Island to pause or stop without opening the app.

APPLE WATCH & AIRPODS PRO
The Watch app mirrors your workout with its own countdown, progress ring, and haptics. Live heart rate from Apple Watch or AirPods Pro shows in the app during your session.

CONTROL CENTER WIDGET
Add Interval-Timer to Control Center. One tap starts your last-used workout - no need to open the app.

WORKOUT PROGRAMS
Build programs with individual exercises, each with its own work and rest timing. Add reference photos so you always know what to do. Exercise names are announced by voice at each transition - train eyes-free.

SHARE & IMPORT WORKOUTS
Share your workout programs with friends via link. Import shared workouts with a one-tap preview. Save up to 3 programs for free - unlimited with Pro.

STREAKS & TRENDS
Track your consecutive workout days with streak reminders. View weekly frequency, monthly duration, and calorie trends with charts. Export your full workout history as CSV.

ACHIEVEMENT BADGES
Earn badges for workout milestones: 7, 30, and 100-day streaks plus 10, 50, 100, and 500 total workouts. Celebrate with haptic feedback after each session.

FEEDBACK & AUDIO
3-2-1 countdown haptics before each transition. Custom haptic patterns for intervals and workout completion. Voice announcements for exercise names and round numbers. Your music keeps playing - the app ducks it during announcements.

HEALTH & PRIVACY
HealthKit integration logs every completed workout as a HIIT session in Apple Health. Heart rate data stays on your device. Anonymous crash reports and aggregate feature usage are collected via Firebase - no Health data, no advertising ID, no account.
