A white noise fan, made for sleep
Fan of Sleep turns your phone into a quiet bedside fan. Pick a speed, layer in nature sounds, and let the sleep timer fade it all out once you’re asleep.
Three fan speeds
Low, medium and high. Each one loops without a gap, so there's no click to wake you.
Rain & thunder
Steady rain on its own, or a rolling thunderstorm for nights that need something deeper.
Ocean waves
Slow surf washing in and out, a classic for drifting off.
Rainforest
The deep, layered calm of a rainforest.
Crackling fire
A cozy campfire, soft pops and all.
Your own mix
Layer any of the six nature sounds over the fan and set each one's volume.
Sleep timer
Pick 15 minutes to 8 hours, or a time of day. The sound fades out gently instead of cutting off.
Your colors
Six gradients to match your room, so the screen stays easy on sleepy eyes.
Questions
Why do people sleep better with a fan on?
A fan makes a steady, even sound. It covers sudden noises like traffic, a partner snoring or a dog barking, so they're less likely to wake you, and for many people the hum becomes a cue that it's time to sleep. Fan of Sleep gives you that sound without a fan blowing on you all night.
Is a fan sound the same as white noise?
Close. True white noise has equal energy at every pitch and can sound hissy. A fan's sound is lower and softer, nearer to brown or pink noise, which many people find more soothing. Fan of Sleep has that fan sound at three speeds.
Does it keep playing when my screen is off?
Yes. Lock your phone or switch apps and the fan keeps running until you stop it or the sleep timer ends.
How does the sleep timer work?
Choose a preset from 15 minutes to 8 hours, or pick the time you want it to stop. When the time comes, everything fades out over a few seconds instead of cutting off.
Can I mix nature sounds with the fan?
Yes. Add rain, waves, rainforest, fire, wind or a thunderstorm on top of the fan, then open the mixer to set each sound's volume. Your mix is remembered for next time.
Which devices does it work on?
Fan of Sleep is on the App Store for iPhone and iPad, and on Google Play for Android phones.
