Sleep music with no loop point to wake you

The problem with most sleep tracks is the seam. A thirty-minute recording set to repeat has a moment where it ends and starts again, and that moment is a change in the room — quiet enough to ignore while you are awake, and quite capable of surfacing you at two in the morning. StillTune has no seam because it has no recording. Sleep mode is composed continuously, phrase by phrase, for as long as you leave it running.

It gets slower and thinner as it goes

Sleep mode is not simply a quieter version of the daytime sound. The phrasing spaces out, the filter closes down toward the low end, and the arrangement drops material as it settles — long sustained tones, glass and soft bells arriving further and further apart, with the low pad carrying most of it. Nothing arrives suddenly, and nothing builds to a peak, because there is no peak in the shape.

A timer that fades instead of cutting

Set the sleep timer and it will bring the level down gradually and stop on its own, so there is no abrupt silence at the end either. If you fall asleep before it runs out, it handles the rest. Playback keeps going with the screen off and answers the Lock Screen controls, so you are not opening the app in the dark to pause it.

Airplane Mode all night, with nothing downloaded

This is the part that surprises people. StillTune does not download audio. It stores the score — the notes and their timing — which is megabytes rather than gigabytes, and your phone performs it locally. Six hours of music is a small fraction of what six hours of streamed audio would cost you in data or storage.

So you can put the phone in Airplane Mode at bedtime and it keeps playing: no Wi-Fi, no mobile data, no radio next to your head all night. Play a mode once while connected and it is loaded; after that it is self-sufficient. Come back online whenever you want new material.

Noise and weather, if silence is not the problem

Sometimes the issue is not that the room is too quiet but that it is too inconsistent — a neighbour, traffic, a partner. Every mode runs from a Sound DNA recipe you can adjust while it plays, so you can raise a steady bed underneath the music:

• Brown noise for the deepest, most low-weighted masking, or pink noise for something softer and more even.
• White noise when the sound you need covered is higher up.
• Rain, ocean waves, wind, distant thunder or a fire when you would rather have weather than a flat bed.

You can also drop the music almost out entirely and keep only the textures, if what you actually want tonight is rain. Save the mix, or browse the community sounds library for recipes other people sleep to.

Start tonight

No account is needed to listen. Open the player, choose Sleep, set a timer if you want one, and press play. The same engine also runs a focus music mode for the other end of the day, and a Drift mode for when you are not trying to do anything in particular.
