Installing a beta build

Three steps, no Play Store required.

01

Request access

Beta builds are distributed directly while we finish Play Store review — request access and we'll send the current APK.

02

Allow sideloading

Enable "Install unknown apps" for your browser or file manager in Android Settings, then open the downloaded APK.

03

Plug in and go

Connect a supported pedal or USB audio interface — Harmonix detects hardware automatically on launch.

Beta software — features and performance are still being tuned. iPhone, Mac, Linux, and Windows builds are finishing certification; see all platforms.
