This is a mobile music application developed with React Native, created by the author “lyswhut”. It targets Android devices (Android 5 and above) and is designed for listening to and managing music, using Redux for state management and integrating custom music sources. The project supports “data-sync” so that users can deploy a server and keep playlists or libraries in sync across devices. The README clearly states that the UI and default behaviour aren’t especially geared toward new users — you’re encouraged to explore settings and adjust according to your preferences. It is open-source under the Apache-2.0 license, and has accumulated a solid community (14,600+ stars, 1,700+ forks). Because it supports custom sources (including non-official music platforms) the team includes disclaimers around copyright, clarifying that the project does not take responsibility for the legality or correctness of the audio data you play.
