Interval Timer: Workout & Rest

Whether you're doing Tabata in the gym, HIIT in your living room, or a custom circuit on the track — Interval Timer keeps you focused on the work, not the screen.

READY IN SECONDS
Built-in presets for Tabata, HIIT, and EMOM mean you can go from zero to working out in one tap. No setup. No guesswork. Just pick a preset and start.

BUILT AROUND YOU
Create and save custom workouts with your own work duration, rest time, round count, and exercise count. Every detail is yours to control. Save as many presets as you want.

ON YOUR WRIST
The independent Apple Watch app gives you a full timer right on your wrist. Leave your phone in the bag. Your workout syncs automatically — start from the watch, finish on the phone.

STAY IN THE ZONE
Live Activity and Dynamic Island support keeps your timer visible even when your phone is locked. See your current phase, time remaining, and progress — without unlocking your phone.

TRACK YOUR PROGRESS
Every completed workout is logged automatically. See your total sessions, total time, current streak, and weekly chart at a glance. Know exactly how consistent you've been.

CLEAN. FAST. FOCUSED.
Designed with a dark interface and zero distractions. No ads. No bloat. Just a timer that works as hard as you do.
