Sleepdalf
Carries the moon lantern
Sleepdalf
A drowsy old dream wizard in slippers and a starry nightcap. Yawns more than he talks, and knows exactly how much rain is the right amount of rain.
The mixer
Every night gets its own mix.
A mix is a stack of sounds playing together. Start from a ready-made one like Rainy cabin, then turn each layer up or down until it sounds like your kind of quiet.
Plays while you drift off
Seamless loops with the screen locked. Free mixes fade out softly after 15 minutes; with Plus they play until morning.
Real sounds, soft tones
Recorded rain, creeks, waves and forests, plus pink noise, 174 to 528 Hz tones and binaural beats.
Save your favourites
Keep the mix that finally worked and find it again tomorrow night.

PLUS
Rain and a slow sea. Very cozy.

Questions
Before you ask.
When does Sleepdalf launch?
We're building it now and will launch on iPhone and Android at the same time. Leave your email and you'll hear the day it's out.
Does it work with my screen off?
Yes. Mixes keep playing with the phone locked. On the free plan they fade out after 15 minutes; with Plus they can play all night.
What happens after 15 free minutes?
The sound fades out slowly, so nothing jolts you awake. The next time you open the app, your guide will offer you a free trial of Plus.
Is there an account to create?
No. You open the app and press play. Your saved mixes stay on your phone.
Be first in line when the lights go out.
