Brume: Ambient Sound Mixer

Brume is a calm, private ambient sound mixer. Tap sounds to layer them, rain over distant thunder over a crackling record, set each one's volume, and drift off.

PRIVATE BY DESIGN

No ads. No analytics. No accounts.
Works offline: every sound ships inside the app. Nothing streams, nothing is collected.
No permission prompts. Brume never asks you for anything.
The only times Brume touches the network are Google Play's billing for the one-time purchase, and casting if you use it.
