Your iPhone can stop your music when you fall asleep. It takes seven steps through the Clock app, and you have to redo it every night. Stereo82 does it in one. Set a timer, pick something from your own library, and your music switches off on its own — from a seven-segment clock face that stays on your nightstand. Stereo82 is the player, not a remote control for one. It reads the music already on your device, so it works whether you subscribe to Apple Music or built your library one album at a time. THE SLEEP TIMER • Play your own songs, albums and playlists, or 21 built-in ambient sounds • Your music switches off when the timer ends; ambient sounds fade out gently • Add 5, 10 or 15 minutes from the Lock Screen or Dynamic Island, without unlocking your phone THE CLOCK • A seven-segment display in eight colors, on eight backgrounds • Built to be readable at 3am and to look like it belongs on a nightstand • A real iPad app, not a stretched phone app — an iPad on the nightstand makes a genuinely better bedside clock AMBIENT SOUNDS • Rain, ocean, thunder, forest, crickets, fireplace, wind, stream, and white, pink and brown noise • Run them on their own, or alongside the timer ALARM CLOCK • Repeating weekday alarm with snooze INTERVAL TIMERS • Sequential workout timers with Live Activity support • Save sessions as reusable presets EVERYTHING STAYS ON YOUR DEVICE No accounts. No ads. No data collection. Your library and your listening never leave your phone. STEREO82 PREMIUM Stereo82 requires a subscription, and new subscribers start with a 7-day free trial.
