About this app

Some nights the room is too quiet. Other nights it's too loud. Sleepool lets you fill it with a sound you build yourself: rain tapping on the window, a fan humming in the corner, a little brown noise underneath. Set the timer, close your eyes, and it fades out on its own once you're asleep.

No account. No internet needed. No subscription.

50+ SOUNDS TO CHOOSE FROM
Noise: white, pink, brown and green noise
Rain and nature: light rain, heavy rain, rain on a window, on an umbrella or a tent, thunderstorms, ocean waves, a stream, a waterfall, wind, forest birds, night insects, frogs, cicadas, owls, a crackling campfire and more
ASMR: bubbles, cave drips, keyboard typing, pencil on paper, turning pages, a purring cat, a heartbeat, a ticking clock and more
Meditation: singing bowl, wind chimes, a music box lullaby, delta waves, ambient pad, low drone
Everyday: fan, café, airplane cabin, train, car ride, washing machine, hair dryer, vacuum, air conditioner, city at night

Yes, the hair dryer and the vacuum are there on purpose. Some people can't sleep without them.

MAKE IT YOURS
Tap a sound to add it, then drag its slider until it feels right. Rain a bit louder, thunder a bit further away. When you land on something you like, save it and bring it back with one tap tomorrow night.
Not sure where to start? Try one of the ready-made mixes like Rainy night, Camping night or Seaside.

A TIMER THAT WON'T WAKE YOU UP
Pick anything from 15 minutes to 8 hours, or set your own time up to 12 hours. When it ends, the sound slowly fades away instead of cutting off in the middle of a dream.

BRING YOUR OWN SOUNDS
That beach you recorded last summer. The old fan from your childhood room. Any audio or video file on your phone can become a seamless loop. Choose the part you want, preview it, and match its volume to the other sounds.
Your files stay on your phone, and Sleepool doesn't ask for storage permission.
