LocalJam

Download

LocalJam is Android first. Every device in a jam needs to be on the same Wi-Fi or hotspot, and a guest without the app can always listen from a browser.

Android

The main release

Google Play is coming soon. Until then, the APK is attached to each release on GitHub: download it on your phone, open it, and allow your browser or file manager to install apps when Android asks.

Google PlayComing soon Android APK and desktopGitHub Releases

Before you install

  • The GitHub APK and the Google Play build are signed with different keys and can’t update each other. Uninstall one before installing the other. Uninstalling removes the app’s data on that phone, including jam history.
  • Each release lists its files and their checksums in SHA256SUMS.txt.
  • If the releases page has no release yet, the first one hasn’t been published.

Other platforms

Desktop builds are on GitHub Releases too. A desktop build that fails is left out of a release rather than holding Android back, so a release may not carry every desktop file.

Build it yourself

LocalJam is open source under the MIT licence. The README has the toolchain and steps for every platform, and a headless command-line host and guest for testing without a second phone. Changes are listed in the changelog.
