Sound Cue is a custom interval timer for workouts that need more than a last-second beep. Place spoken countdowns or beep cues exactly where you need them—early enough to prepare, change equipment, reset, or breathe before the next effort. BUILD EACH PART OF YOUR WORKOUT Choose how many timed work intervals (reps) and sets you want, then time Get Ready, Work, Rest, and Between Sets independently. Build a simple round timer or use Sound Cue for HIIT, Tabata, boxing, circuits, mobility, cardio, climbing, and more. PLACE CUES WHERE YOU NEED THEM Add up to five sound cues to each workout part: Get Ready, Work, Rest, or Between Sets. For each cue, choose a beep or spoken number. Each cue can play once, every second as a countdown, or on a custom repeating schedule. Set when it begins and whether repeating cues stop after a chosen count or continue until that workout part ends. FOLLOW ALONG BY SOUND Start the timer and stay focused on your workout. Phase announcements and scheduled cues tell you when to work, rest, and reset without checking the screen. STAY IN THE FLOW • Track time remaining, the current set and rep, completion percentage, and the next interval at a glance. • Choose beep or voice alerts—or turn them off—for interval changes and workout completion. • Adjust sound volume, turn haptic feedback on or off, and choose whether cues briefly lower music or other audio. • Hear scheduled cues while your iPhone is locked or while using another app. SAVE AND ORGANIZE WORKOUTS The free library starts with three included workouts and holds up to five saved workouts in total. Rename, reorder, edit, and reuse them. Use named groups to keep related workouts together and easy to find. A one-time in-app purchase expands the limit to 100 saved workouts. PRIVATE BY DESIGN Sound Cue has no ads, analytics, or tracking. Workouts, cues, and preferences are stored locally and are not transmitted by Sound Cue. Build your intervals, press Start, and let Sound Cue keep you moving.
