Endless Instrumental Music for Focus, Sleep & Relaxation
StillTune plays endless instrumental music that keeps changing: real melody, harmony and instruments for focus, sleep and relaxation. Every sound is synthesized on your device, so it keeps playing offline. No loops, no pre-recorded files — ad-free with StillTune Pro.
Music that is written while you listen
StillTune has no track list, because there are no tracks. Each phrase of music is composed in real time, then performed on your device by a synthesis engine: bells, glass, handpan, flute and low sustained pads, moving through real chord changes rather than looping a recorded bed. Because nothing is pre-rendered, listening sessions rarely sound the same twice, and a session can run as long as you want without arriving back at a seam.
Four modes
Focus holds a steady pulse and a narrow tonal range, so it settles behind reading, studying or deep work instead of competing with it. Sleep slows and thins out as it plays, dropping toward long low tones for quiet nights — Deep Sleep is Sleep's heavier variant, for nights an ordinary sleep preset still feels too close to the surface. Relax is warmer and unhurried, for coming down at the end of a day. Drift opens the spacing out for unstructured listening and creative pauses.
Shape it with Sound DNA
Every mode runs from a Sound DNA recipe you can open and change while it plays: raise the drones, pull the bells back, add rain, wind, ocean waves, distant thunder, a crackling fire or the murmur of a quiet cafe, and layer in white, pink or brown noise. Save a mix you like, or publish it so other people can play it.
It works offline
No audio is streamed and there are no audio files to download, because the sound is synthesized on your device as it plays. Drones, pads, noise and the weather textures all run locally with no connection at all, and a loaded mode keeps its melodies going for hours in Airplane Mode, with no Wi-Fi, no mobile data, no gigabytes of downloads sitting on your phone.
