IPHONE AND ANDROID · NO SUBSCRIPTION
Twenty sounds to fall asleep to. Nothing else.
A library of ambient loops to play on their own or layered together. A timer that fades out. A night mode that is almost dark. No guided meditation, no sleep tracking, no account.
The 20 ambient sounds
Long loops, cleanly recorded and played continuously — no audible seam, no duration on screen. Four sounds are free, one from each family.

Layer up to six sounds
Each sound is a horizontal layer. Drag it to set its volume: the target is the full width of the screen, so the gesture works in the dark, one-handed, without aiming. Save the blend and it comes back with one tap the next night.
- Adjust without lookingThe layer spans the whole width, so your thumb finds the target with your eyes closed.
- Saved mixesLast night's blend is waiting at the top of the home screen, one tap away.
- Fade outThe volume comes down over the last five minutes of the timer. Never an abrupt cut.
- Offline playbackThe loops live on the phone. Airplane mode, basement, night train: it plays.
Timer
Preset durations, reachable while playing without opening settings. No elapsed time on screen.
Night mode
While a sound plays, the screen dims to almost nothing — just enough to stop it at 3 a.m.
Widget
Start a sound from the lock screen, with its timer, without opening the app.

Frequently asked questions
Is there a subscription?
No. Four sounds are free, and the full version is a one-time purchase — the price for your country is shown on this page and in the store. There is no subscription anywhere in the app.
Do I need an account?
No. No email, no sign-up, no advertising. Your mixes stay on your phone.
Does it work without a connection?
Yes. All 20 loops are downloaded with the app and played locally, airplane mode included.
How many sounds can be layered?
Up to six at a time, each with its own volume, and the blend can be saved to start it again with one tap.
Do the sounds stop during the night?
That depends on the timer: 15 minutes to 1 h 30, or continuous playback. A fade-out brings the volume down before it stops.
Is there meditation or are there sleep stories?
No, and there will not be. Sleep.fm does one thing: play ambient sounds to fall asleep to.
