Driftlet helps you focus, relax and fall asleep with sound that is generated live on your phone. Harmonies, chimes, rain and waves are synthesized as you listen, so every moment is new: no recorded tracks, no loops, no sudden song change just as you settle in.
Coming soon to Android · 7-day free trial · iOS in the works



Made for moments like these
For focus, steady harmonies over a barely-there pulse keep distractions out. To relax, the chords slow down and waves roll in the distance. For sleep, everything sinks lower and softer, with rain or the sea.

There is not a single recorded track in Driftlet. Where the chords go, when a chime rings, where a raindrop lands: all of it is decided as it plays. So it can run as long as you like, with no loops and no gaps between songs.

Each state has a two-dimensional tuning pad. In focus, move between free and steady, calm and lively. In relax, set how bright and how rich it is. In sleep, choose between rain and sea, and how much melody you want. Wherever your finger goes, the sound slowly follows.

Set it and forget it: the sound moves through the routine by itself. There are ready-made routines for falling asleep, napping, breathing and waking up.

Stops after 15 to 90 minutes, fading out over the last minute. Sleep mode also grows gently quieter over its first half hour.
Keeps playing with the screen off; control it from the lock screen, the notification or your headphones. Pauses for calls, stops when headphones are unplugged.
Start focus, relax or sleep with one tap, without opening the app.
The sound engine is built for long sessions and stops computing entirely when paused.
Every sound is made on your phone. No internet needed, and no personal data collected.
Follow the system or pick light or dark. The visuals drift slowly with the sound, easy on the eyes at night.
White noise is a single sound; playlists loop and change songs. Driftlet generates its sound as it plays, with harmony and melody that stay calm, so it can run for hours without pulling your attention.
No internet needed. Every sound is synthesized live on your phone, and Driftlet collects no personal data.
Yes. The engine is optimized for long sessions and uses very little power. You can also set a timer and it will fade out when it ends.
No. It keeps playing with the screen locked; control it from the lock screen, the notification or your headphones, or start it from the home-screen widget.
Try everything free for 7 days. Focus, relax and sleep, the tuning pad and the sleep timer stay free for good; nap, meditate, commute and the routines are part of the full version, a one-time purchase with no subscription.
