## What is Overtone?

Overtone is an interval timer that stays out of the way of your music.

Set a total time and a beep interval, or build rounds of work and rest. Press Start, lock your phone, put it in your pocket. The cues play over whatever you are listening to, without pausing it and without turning it down.

BUILT FOR HIIT, CIRCUITS, TABATA AND TEMPO RUNS
• Simple mode: total time plus a beep every X seconds
• Rounds mode: work, rest, rounds, warm-up and cool-down, with a distinct cue at every change
• 3-2-1 countdown ticks before each cue, and a get-ready lead-in before you start
• Pause, skip ahead, or extend without breaking stride

YOUR MUSIC KEEPS PLAYING
Overtone mixes with other apps instead of interrupting them. Spotify, Apple Music, podcasts and audiobooks carry on at full volume.

ON THE LOCK SCREEN AND IN THE DYNAMIC ISLAND
See the current phase and the countdown without unlocking. Pause and resume from the Live Activity.

YOUR SOUNDS
Pick from built-in chirps, beeps, bells and gongs, or record your own three-second cue with the microphone. Yes, you can make it your own voice.

FREE FOR A FULL MONTH, THEN ONE DOLLAR
