Stop adapting to your app. Make it adapt to you.
Custom tabs
Build your own navigation — a tab for any slice of your library: a genre, a decade, a set of artists, your live recordings.
Customizable Featured screen
Shortcut tabs and a Featured screen you arrange yourself put the music you reach for most one tap away.
Smart playlists that actually work
Rules-based playlists that auto-refresh as your library grows and your listening changes — no manual upkeep.
Custom tags
Tag and organize your library in nearly unlimited ways, far beyond the usual genre and artist fields.
On-device metadata editor
A full editor for ID3, MP4/iTunes, APE and Vorbis tags — plus cover art, favorites, and star ratings — right on your device.
Hi-res sound: EQ, volume normalization & USB DAC support
The kind of playback control audiophiles actually want.
10-band equalizer
Shape your sound with a 10-band EQ and 20+ presets, or dial in your own.
Volume normalization
ReplayGain and Sound Check keep every track at an even, comfortable level — no more reaching for the volume.
Gapless, crossfade & forced-gap
Three playback modes so live albums, DJ sets, and everything in between flow exactly the way they should.
Hi-res & DSD via USB DAC
Connect an external USB DAC for true hi-res output at 96kHz/24-bit and beyond — including bit-perfect DSD (DSD64–DSD256) over DoP, with automatic high-quality PCM conversion on every other output.
Lyrics, karaoke mode, podcasts & audiobooks
Sing along, settle in, and listen your way — long sessions included.
Lyrics & karaoke
Timed and untimed lyrics from embedded tags or LRC sidecar files, with karaoke-style highlighting that follows the track line by line. Drop your own .lrc files in for any song — iTunes tracks included.
Podcasts & audiobooks
Dedicated media types with their own filtering and sorting, an In Progress view, and one-tap resume that picks up right where you left off.
Sleep timer & variable speed
Drift off with a sleep timer, or slow things down and speed them up from 0.5× to 2× — ideal for audiobooks, podcasts, and language tracks.

Your music comes with you — car, home, and on the go.

Last.fm scrobbling
Connect your Last.fm account and BTR AMP scrobbles what you play to build your listening history — offline scrobbles are queued and retried automatically.
