No account. No download. No Spotify or Apple Music login. It works with any music source: streaming apps, vinyl, YouTube, live instruments. Grant microphone access and the particles respond to what they hear. Bass drives pulsation. Mids shift color. Highs scatter and spark.

Process

01

Play anything

Spotify, Apple Music, vinyl, a live instrument, YouTube on your phone. If it makes sound near your device, it works.

02

One permission

Your browser asks for microphone access. Nothing is recorded. Nothing leaves your device.

03

Immerse

Particles pulse with every beat. The camera drifts through 33 particle universes.

Beta

Now imagine the lyrics appearing

The app listens to what you are playing, identifies the song, and pulls particles out of the simulation to form the words being sung. Visuals work with every song. Lyrics are available for most popular tracks.

Synced in real time. Automatically detects the next song. During instrumental breaks, particles return to the shape. Lyrics are in beta and may not be available for every track.

Everything is free.

33 simulations, 5 visual styles, cinematic camera, auto-shuffle, full controls, and lyrics detection. No account. No login. No paywall.
