A calm, private ambient sound mixer for Android. Blend up to eight soundscapes, set a sleep timer, and drift off.
Brume never connects to the internet. Every sound is synthesized in-house and ships inside the app — nothing streams, nothing phones home, nothing is collected. The app never shows you a single permission prompt.
The only networked component is Google Play's own billing client, used solely if you buy Brume Pro. Read the whole privacy story →
Tap sounds to layer them; each has its own volume. Five are free forever — enough for the classic rain-thunder-campfire night.
Every soundscape loops with no gap and no seam — engineered, measured, and verified.
A proper media service keeps the sound going with the screen dark, with lockscreen controls.
5 minutes to 4 hours, ending in a gentle 30-second fade to silence.
A near-black dimmed clock that keeps watch while the sound plays.
Six slots for the blends that work — back in one tap.
No streaming, no radios, no wakeups beyond the audio itself.
One purchase on Google Play. Restores on any of your devices. That's the whole business model — no ads to show you, no data to sell.
Direct download, signed by us. Android 8.0+. Your phone will ask you to allow installs from your browser — that's Android's standard flow for apps outside the Play Store. The Play listing is rolling out now; purchases of Brume Pro go through Google Play.
