What it fixes
Sound familiar?
“Silence keeps me awake, but every sleep sound loops with a click.”
With Seren
Real recordings of rain and thunderstorms, looped seamlessly, and noise colours generated live so they never repeat.
“I don't want the sound playing all night.”
With Seren
With Seren Premium, a sleep timer stops it after a set time or at a set clock time, fading out gently over up to 10 minutes.
“My phone lights up the room.”
With Seren
Bedside mode shows a dim clock and keeps the screen dark all night.
01
Mix your own storm
Layer any sounds and set each volume. Warmth softens the high end, so the storm feels further away.
- Rain on a car, a skylight, a roof or a tent
- Thunderstorms, ocean waves, forest at night, wind, fireplace and campfire
- Brown, pink, green and white noise, and a fan
02
Let it fade out
Pick how long to play, or a time to stop, and how long the fade should be. Turn on bedside mode as the timer starts.
- Keeps playing in the background and from the Lock Screen
- Plays under a podcast or audiobook
