Ten clocks for the way people actually train. Interval, Tabata, Rounds and Stopwatch are free. AMRAP, EMOM, For Time, rest-between-sets, hangboard repeaters and splits come with a single $3.99 purchase — one time, not a subscription. All ten are visible from the first launch, and every one opens its full setup screen before you decide. A CLOCK THAT CANNOT DRIFT Every reading is derived from the wall clock rather than counted tick by tick, so it does not gain or lose a second over a long session and it never has to catch up. Lock the screen mid-round and the numbers are still right when you look back. READABLE ACROSS A GYM The whole screen floods green while you rest, so work and rest are told apart from the far side of a room without reading a digit. Three short beeps count you into every change and a longer tone marks it, ducking your music rather than stopping it. HONEST ABOUT THE NUMBERS Elapsed, remaining and total always agree. Rounds are counted the way you would count them out loud. Nothing is rounded to make a screen look tidier. WHAT IT DOES NOT DO No account. No sign-in. No server. No analytics, no advertising, no tracking. Your configurations, presets and session history are written to your own device and stay there. Export a full backup whenever you like, free — your data should always be able to leave the phone. ALSO IN PRO Class mode for a wall display, writing finished workouts to Apple Health, and exporting your history as CSV. Twelve languages, including full right-to-left support for Arabic. iPhone and iPad, every orientation.
