Auxio

Auxio is a music player for Android, published by Alexander Capehart. It occupies the plain end of the audio-app spectrum: the stated aim is a simple, rational player rather than a media hub with streaming accounts, social feeds, or plugin layers. If your listening happens through files you already keep on the device, this is the category of app it belongs to.

The project is released under the GPL-3.0-only license, so the source can be read, modified, and redistributed under the same terms, and any derivative has to stay under that license. Distribution is Android-only, with no desktop, iOS, or web counterpart listed, so it will not serve as one half of a cross-platform pair. Feature specifics beyond the player role are not covered by the facts available here; the project's own repository and release notes are the place to check whether a particular format, tag behavior, or interface option is supported.
