Ultrasonic is free and open-source music streaming Android client for Subsonic API (version 1.7.0 or higher) compatible servers.

We currently don't have that much time to spend developing Subsonic, so any contributions or active developers are always welcomed.

App is available to download at following stores:

Warning: All three versions (Google Play, F-Droid and the APKs) are not compatible (not signed by the same key)! You must uninstall one to install the other, which will delete all your data.

If you want to use the version downloaded from F-Droid or form Github with Android Auto, you must enable Unknown Sources as it is described in this wiki page.

First, see if your issue haven’t been yet reported here, otherwise open a new issue.

If you are using Madsonic 5.1.X several sections of Ultrasonic will not work. This is caused by bad implementation of Subsonic API by Madsonic. For more info about this you can read this bug.

See CONTRIBUTING.

Other Subsonic API implementations should work as well as long as they follow API documentation.
