Press and review

Brumm Kids in three sentences.

Brumm Kids is a free music app for children in the phone's browser. A child hums or sings two bars, the app sets the melody in time and in key and plays it back in the beat, first with the child's voice, then as an instrument. No account, no ads, no purchases; the recordings stay on the phone, and sharing is only by a link that a grown-up makes behind a gate.

Feel free to quote it word for word.

Who makes it.

Daniel Breyer, Berlin. Studied theoretical quantum physics, ten years of product development, among others for a streaming start-up at Deutsche Grammophon, twenty years of club music as one half of Acado. He built Brumm, an instrument you play by humming; Brumm Kids is the same technology, made usable for children. Plus Mika, a real husky from Berlin-Neukölln, who makes the beat in the app: this is Mika.
