OuterTune brings YouTube Music search and playback together with a player for local audio files, so listeners can manage different music sources in one app. It can find songs, videos, albums, and playlists, and supports background playback and saving songs for offline listening. You can also synchronize an account and its playlists with YouTube Music, helping keep collections aligned between the service and the client. For local listening, the player supports common formats including MP3, FLAC, and OGG.

Finding and organizing music

Search covers YouTube Music songs, videos, albums, and playlists, while local files can be added to the same broader listening setup. Library filters for artist, album, and genre provide ways to browse a collection by its details rather than relying only on a single playlist. Playlist and account synchronization can complement that organization for people who use YouTube Music collections as well as audio stored on their device.

Queues and playback controls

OuterTune supports multiple playback queues and dynamic playlists, giving listeners options for arranging what plays next. Playback controls are also available through notifications and shortcuts, which can be useful when switching between music and other apps. An automatic shutdown timer offers another playback option, while background playback lets music continue when the app is not in the foreground.

Sound and listening details

An equalizer and audio normalization options let users adjust playback, and lyrics and enhanced metadata are supported through custom extractors. These tools add listening and track-detail options alongside the basic player, rather than limiting the app to searching and starting music.

Appearance and availability

The interface uses Material Design 3 and offers themes and dark mode for visual adjustment. The source describes OuterTune as free and open-source and identifies it as an Android app, not an iOS, Windows, or Mac release. It also notes that YouTube Music integration may be limited in some regions, and that users could encounter occasional bugs or stability issues.
