Ambio

Find your focus

Blend up to three ambient sounds into one soundscape, set how loud each sits, and let a timer or a plan of focus and break steps hold the session. The whole app takes its colour from the mix you built.

Twelve sounds, three at a time

Rain over a distant café. Fireplace under wind. The background gradient and the particles behind the timer are blended from every sound in your mix, so the app looks like what you made.

On F-Droid it is a reproducible build: F-Droid compiles the tagged commit on its own servers and only publishes the APK once it matches ours byte for byte, so the app you install is provably built from the source you can read.
