Mizzle is a white noise and sleep sound app for people who just want to fall asleep and be left alone.

No accounts. No sign-in. No ads. No analytics, no crash reporting, no third-party tracking. Mizzle makes no network requests of its own and has no servers to send anything to. One payment unlocks everything, forever: there is no subscription and nothing else to buy.

FIFTY-FOUR SOUNDS, EACH ONE MEASURED
Not a library you scroll through. Every sound in Mizzle has been levelled by hand and checked against the same tests: that it does not audibly repeat, that it sits at the same loudness as everything else, and that its energy lands where a phone speaker can actually reproduce it. Several recordings were rejected outright for failing that last one. Nothing here is a thirty-second clip on a loop.

Nineteen of the fifty-four are synthesized on your phone as they play, so they never repeat the same way twice. The other thirty-five are Creative Commons field recordings, chosen and trimmed one at a time, and every one of them is credited inside the app.

Rain on a window, rain on leaves, a creek, a river, waves, a steam train, a sleeper car, cabin hush, a real fire, crickets, a dawn chorus, six colours of noise, and a few quiet melodies. Seven groups: noise colours, rain, water, nature, home, travel and melodies.

LAYER UP TO FIVE
Mix up to five sounds at once with a volume slider on each. Most sounds also shape from calm to wild, so a downpour can be a drizzle or a deluge without leaving the mixer. Save your own mixes and start them from a home screen widget or a Quick Settings tile. Hold any sound to keep it in Favourites.

FOR THE NIGHT
- A sleep timer that fades out over the last thirty seconds instead of stopping dead
- Overnight softening, to get gradually quieter after a set hour
- A bedtime reminder
- A dimmable bedside clock for the small hours

ABOUT THE INTERNET PERMISSION
Mizzle holds the Android internet permission, and it is there for exactly one reason: Google Play Billing, which is how the unlock is sold. The purchase is handled by the Play Store app, not by Mizzle. We would rather say that here than have you find it on this page and wonder.

FREE AND PAID
Ten sounds are free, including at least one in every group, and four of the presets play without paying. One optional payment unlocks the other forty-four, for good.
