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.

PepTimer is an interval timer that shows you each exercise and calls out the next one. Everything you need to train is free: no ads, no account, no subscription. A voice counts you down and calls out what's coming – laid over your music instead of pausing it, even with your iPhone locked in your pocket. 80+ EXERCISES THAT SHOW YOU HOW • Every exercise has a small figure that demonstrates the move – some from the side and from the front. In lunges the figure switches legs • From strength and cardio to stretches like the downward dog or the cobra • Pilates moves like the Hundred, swimming and the half roll-down, also as the ready-made workouts "Pilates short" and "Pilates long" • During the get-ready countdown and every break, you see what's next, and the current exercise while you do it, too • Browse them in the Exercises tab, with search (under an exercise's old name too) and body-area filters, and build a workout straight from your picks A VOICE THAT GETS YOU THROUGH • Announces the next exercise, counts you down, calls halfway and the last round • Tells you when to switch sides in one-sided moves • Grace in English, Anna in German, whatever the app's language • Or no voice at all, tones only START RIGHT AWAY • "What do you feel like today?": ready-made workouts for Upper body, Legs & glutes, Core, Full body, No jumping, Tabata, Warm-up & Cool-down, Mobility and Pilates, the 7-minute workout among them • Tabata: classic, with exercises or in four blocks • A quick look at every exercise before you start • Templates for HIIT, EMOM, AMRAP, circuits and boxing rounds YOUR OWN WORKOUTS • As many as you like: exercises from the catalog or with names of your own • Add several exercises at once, with one length for all of them and rests in between if you like • In blocks: say 10 rounds of burpees, a break, then 10 rounds of planks • Drag to reorder, and undo a delete • Share by link: whoever opens it adds your workout in one tap EVEN WITH THE SCREEN LOCKED • Announcements and tones keep going when you lock the screen or switch to another app • On the lock screen and in the Dynamic Island: the time left and a bar of every phase of your workout APPLE WATCH AND APPLE HEALTH • Your iPhone's workout on your wrist too: the phase, the time, the exercise and what comes next • A vibration at every phase change, even with your wrist down • Your heart rate while you train • Pause, resume, skip and end right from the watch • If you like, your workouts go to Apple Health, with or without a watch BUILT FOR TRAINING • Big digits you can read from the mat, portrait and landscape • Figure off, normal or large • Every phase has its own color • Tones: beep, gong, boxing bell or whistle • Vibration on every phase change • Announcement volume independent of your music • Your music dips for announcements – briefly, for longer or not at all • Announcements as captions if you like • Text grows with your text size, up to a cap that keeps every screen readable • The screen stays on while you train • A history of your sessions, with the time trained and the exercises skipped • Light, dark or whatever your iPhone uses PEPTIMER PLUS Buy once, keep it for good. No subscription. • Train together: you lead a workout, and the people next to you join on their own iPhones, all in step. Joining is free. • More voices: Megan, Sam and Reginald in English, Elena, Jonas, Chris and Oma Gerda in German. Listen to them before you buy. • Whatever is added to Plus later is yours at no extra cost • With Family Sharing for everyone in your family YOUR DATA STAYS WITH YOU PepTimer collects nothing. No tracking, no analytics, no server. Your workouts and your history live only on your device, your heart rate and saved sessions only on your devices and in Apple Health. When you train together, the iPhones talk to each other directly, without the internet, and a shared workout travels inside the link itself.
