MMPlayer Music Player is a free multimedia application developed by MASF Software for Android devices. It is a powerful player that allows users to play music files stored on their Android devices with ease. The user interface is modern and intuitive, allowing users to browse their music library by folders, artists, albums, and genres, and to organize music tracks into playlists.

One of the best features of MMPlayer is its three modes of browsing folders with music files: Flat list, Hierarchical In-Place, and Hierarchical Windowed. This makes it easier for users to find the music they want to listen to. In addition, the media library search feature allows users to quickly find specific tracks.

Other key features of MMPlayer include powerful playlist management, smart playlists for most/recently played tracks, recently added tracks, and favorites, compatibility with Android Auto and Android Wear devices, playback control via headphone button control (including Bluetooth headphones), voice commands via Google Assistant, lock screen and media notification controls, multiple color themes, sleep timer, and resizable home screen widget.

MMPlayer Music Player supports a wide range of music file formats, including mp3, mpa, flac, ogg, wav, and others, depending on the device's capabilities.
