Timer app for iPhone

NanoTimer is a free timer app for iPhone, iPad and Mac: plain timers, interval and workout timers, a stopwatch, meditation and a real alarm. No ads, no subscription.

What is in it

  • Timers with presets and your own duration, plus history.
  • Interval and workout: Tabata, HIIT, EMOM, AMRAP, For Time, with warm-up and cooldown.
  • A real AlarmKit alarm that breaks through silent and Focus (iOS 26+).
  • Stopwatch with laps and a calm meditation timer.

Why it is reliable

Timing is anchored to a real moment, not a counter that stalls in the background. Lock your phone, switch apps: the time stays correct. Live Activity and Dynamic Island show the remaining time on your Lock Screen.

Voice cues announce the phases while your own music keeps playing and only ducks briefly. That is exactly where most timer apps fall down.

Free, with a one-time Pro

Building and running every timer type is free, as are voice cues, music ducking, the alarm, the stopwatch and the widget. Pro is a one-time 6.99 euro for an unlimited library and deep stats. Never ads, never a subscription.
