A calm, private ambient sound mixer for Android. Layer soundscapes your way, set a sleep timer, and drift off.
Everything Brume plays ships inside the app. Every sound is bundled on your device — nothing streams, nothing is collected. The app never shows you a single permission prompt.
The only times Brume touches the network are Google Play's billing for the one-time purchase, and casting to your TV if you use it. Read the whole privacy story →
Tap sounds to layer them; each has its own volume. Seven are free forever — the classic rain-thunder-campfire night, plus a creek and pure white noise.
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.
Send your mix to any Google Cast speaker or TV. The speaker plays on its own — your phone can leave the room or sleep.
5 minutes to 8 hours, ending in a gentle 30-second fade to silence — even on the speaker you cast to.
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.
Test Pro free in early access →
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.
