About StillTune: Sleep & Focus Music
StillTune is a sleep and focus music app that composes calm, ambient music live on your phone. Press play and the music starts composing itself. Not a track. Not a playlist. Not a loop. StillTune doesn't play tracks. There aren't any. It writes the music as you listen, note by note. Nothing to queue up. Nothing to pick. Just press the button. FOUR MODES Sleep: slow, and it keeps getting slower. Focus: steady enough to disappear behind your work. Relax: warm, unhurried, for when you need to come down from the day. Drift: open and spacious. Good for thinking sideways. IT'S MUSIC, NOT A NOISE MACHINE There are notes in here. Chords. Changes that actually resolve. It's written for sleep, focus and coming down at the end of the day, not a loop with rain laid over the top. The noise is in there too, if that's what works for you. Push it up under the music, or pull the music out and keep just the noise. MAKE IT YOURS, THEN PASS IT ON Most of these apps hand you a finished sound and hope you like it. StillTune hands you the recipe. Every mode runs on a Sound DNA you can open while it's playing. Push one layer up, pull another back, add rain or wind if you want it. You hear every change the moment you make it. When you land on something good, keep it. Or publish it, and let other people play the exact thing you built. The library in the app is full of them. IT WORKS OFFLINE Nothing is streamed, and there are no audio files to download. The sound is synthesized on your phone as it plays. Flip on Airplane Mode at bedtime and it keeps going for hours, with no Wi-Fi, no mobile data, no gigabytes sitting on your phone. WHERE IT ENDS UP At a desk, Focus turned down far enough to forget it's on. In bed, timer set, phone face down. On a plane, offline, the whole flight. In a room that's too quiet, or one that isn't quiet enough. WHAT'S IN IT • Sleep, Focus, Relax and Drift • A sleep timer that fades out and stops on its own • White, pink and brown noise • Live nature sounds: rain, river, ocean, campfire, crickets and more. Mix up to five at once • Full mixer, every layer with its own fader • Keeps playing with the screen off; Lock Screen controls included • Save the ones you like Optional Pro unlocks 40+ Soundscapes, all of Deep Sleep, every Bloom theme, longer timers, and no ads You don't need an account to listen. Open it and press play. Terms of Use (EULA): https://stilltune.com/legal/app-terms
