Build your own sleep sound
Start with a fan. Then stack sounds on top, each with its own volume. A box fan under soft rain. A tower fan with distant thunder. A ceiling fan over ocean waves and a campfire. Mix it until it sounds exactly right, and the app remembers it for the next night.
Why fan noise beats pure white noise
Fan sounds cover a wider frequency range than synthesized white noise, so they mask interruptions more naturally without feeling harsh. Your brain stops scanning for sounds, your body relaxes, and you drift off, usually within minutes.
What's inside
More than 75 sounds, real recordings, all built to layer: fans and machine hum, white, brown and pink noise, rain and thunder, ocean and rivers, forest, birds, wind and fire.
