More than a last-second beep

Your clock shouldn’t need your eyes.

Sound Cue gives you enough warning to chalk up, reset your stance, change equipment, or simply breathe before the next effort begins.

Interval timer essentials

A closer look at Sound Cue.

What to know when choosing an interval timer app for your workouts.

What can I customize about the sound cues?

Choose each sequence’s timing, sound, and countdown or repeat pattern, separately for every phase. Voice cues speak the remaining numbers. Custom recordings, written spoken instructions, and exercise-name announcements aren’t supported.

Which interval workouts can I build?

Build repeating work-rest intervals for HIIT, Tabata-style sessions, boxing, circuits, climbing, mobility, and cardio. Each Rep is one work interval. Get Ready runs once, Between Sets replaces Rest between sets, and the workout ends after the final effort.

Does the timer work with music and a locked screen?

Yes. An active workout is designed to keep timing and play audio when you lock your iPhone or move Sound Cue to the background. Cues play alongside other audio, and the optional Lower Other Audio setting briefly reduces music volume while cues play.

Does Sound Cue require an account or subscription?

No. The free library holds up to five saved workouts in total, including the starter workouts. An optional one-time purchase expands the limit to 100. There is no Sound Cue account or subscription.
