Hot-pink neon dark mode and a soft pink light mode, 25+ screens, ready to publish under your own brand.

Your whole library, beautifully organised

The app scans the device for MP3, M4A, AAC, WAV, FLAC, OGG and OPUS files in a background isolate, reads ID3 tags and embedded artwork, and sorts everything into Songs, Albums, Artists, Genres, Folders, Favorites, Recently Played and Listening History. Search with recent and trending searches, and a docked mini player on every tab.

Sound that feels right

A real 5-band equalizer with presets (Rock, Pop, Jazz, Bass, Classical, Vocal, Flat), Bass Boost, Virtualizer and Loudness using native Android audio effects.

Lyrics, playlists and background playback

• Synced lyrics (LRC) from a .lrc file next to the song, from embedded tags, or typed in the app
• Playlists: create, rename, delete, reorder and add songs from any screen
• Now Playing with shuffle, repeat, seek, favourite and a queue sheet
• Background playback with notification and lock-screen controls
