Slo Noise

Slo is a sleep and focus sounds app for iPhone, Android and Mac. It ships 150+ curated sounds: brown noise, white noise, pink noise, rain, ocean, wind, fireplace, binaural beats, frequency tones and meditation bells. A mixer gives every sound its own volume slider, so you can layer rain over brown noise and set a timer to fade it out as you fall asleep. The app is designed to run all night: leave a mix playing until morning, or set a sleep timer that fades it out once you are under. For the day there are curated presets and separate categories for noise colors, nature, meditation and lo-fi. If you want to hear it before installing, the players and mixer also run free in your browser at slonoise.com, no account needed. People love our Brown Noise and Deep Brown Noise and claim it helps them sleep a lot. Built by an indie developer. No feed, no streaks, no notifications. Open it, press play, get on with your work or your night.
