FEATURES
Music, sounds and voice cues
Hear every change without looking: your own cues, your own soundtrack, and a big-screen Gym Display
Sounds, voice and vibration
For the warm-up, high intensity, low intensity, cool down, the countdown and the end of the timer, choose a sound, a voice cue or nothing, and turn vibration on or off. Ducking lowers your music while a cue plays, so you never miss one.
Timer music
Pick a default song for a timer, or assign songs to individual intervals, from Apple Music or your music library. Songs from the cloud need an internet connection, and may need an Apple Music subscription.
Gym Display
Put the timer on a larger screen or a mirrored TV: the time left, what’s next and the set, big enough for a whole room to follow.
YOUR NEXT SESSION STARTS HERE
Bring the effort.
We’ll keep the time.
