Everything BTR AMP does
A serious music player for people with a serious collection — no compromises on formats, organization, or sound.
Plays everything
One player for your entire collection — whatever the format, wherever it came from.
Virtually any audio format
Lossless, lossy, and true hi-res — MP3, AAC, M4A/M4B, FLAC, ALAC, AIFF, APE, MPC, TTA, WV, OGG Opus & Vorbis, and now DSD up to DSD256 — plus M3U playlists, up to 96kHz/24-bit and beyond, with the exact codec shown on every track.
iTunes and everything else
Play your iTunes library and your non-iTunes files side by side in one app — even straight from USB drives and memory cards.
Built for huge libraries
Tens of thousands of songs stay as fast and responsive as a handful. 50,000+ tracks, no lag.
Your library, your way
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.
Studio-grade sound
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.
In the moment
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.
Everywhere you listen
Your music comes with you — car, home, and on the go.
Industry-leading CarPlay
A fully customizable Apple CarPlay music player — and your custom tabs come along for the drive.
Just ask Siri
Comprehensive Siri support — tell Siri what you want to hear and BTR AMP plays it.
Bluetooth & AirPlay
Stream to your headphones, speakers, TVs, and anything else you listen on.
Get your music in & out
Your files are never trapped inside the app.
Connect to servers & cloud
Connect straight to your Mac, Windows or Linux computer over SMB, or to Google Drive, OneDrive, WebDAV and iCloud Drive — with background AutoSync that keeps everything up to date.
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.
Transfer to your device
Send music over Wi-Fi with WebDAV/HTTP transfer, use AirDrop and “Copy to BTR AMP” from other apps, or fall back to iTunes File Sharing.
Your files stay yours
A built-in file manager plus iOS Files app integration (“On My iPhone/iPad” → BTR AMP) means your music is always accessible — never locked in.

Loved by serious collectors
4.7 ★ from 1,400+ App Store ratings.
“I’m not sure how I hadn’t heard of this app before because it’s exactly my use case of mixing offline files with Apple Music streaming. It also has a bunch of great customisation options, which I love. This app doesn’t get the attention it deserves.”
Use case: Mixing offline + streaming
“Forget all of those other apps that simply do the same thing as Apple Music with poor sound and little to no support for your music files. BTR AMP has a fantastic UI built specifically for your library and sounds great too!”
Use case: Switching from Apple Music
“If you have a well-curated music collection and want to bring it on the road, BTR AMP is fantastic. There is nothing else like it on the App Store.”
Use case: Large offline library
“BTR AMP is quickly rounding into a very powerful player for the iOS platform, and is highly recommended if you want something far easier to navigate and more robust than the native Apple Music app.”
Use case: Power-user library management

“Probably the most powerful music player for the iPhone”— iphone-ticker.de
Frequently asked questions
How large of a library can BTR AMP handle?
BTR AMP is built for big collections. Tens of thousands of songs across thousands of albums and artists stay fast and responsive — many users run libraries of 50,000+ tracks without lag.
What are custom tabs and how do they work?
Custom tabs let you build your own navigation. Create a tab for any slice of your library — a genre, a decade, a set of artists, your live recordings — and arrange them however you browse. Your tabs even carry over to CarPlay.
Is BTR AMP a subscription app?
You can use BTR AMP for free. Pro unlocks the full feature set — $1.99/week, $3.99/month, or $19.99/year — and there is a one-time $59.99 lifetime option if you would rather not subscribe.
Does my custom organization sync to CarPlay?
Yes. The custom tabs and layouts you set up appear in CarPlay, so your car screen matches how you organize music everywhere else.
Can I import my existing library?
Yes. BTR AMP works with your music regardless of where you bought it or what format it is in. Bring in your existing files and play them offline, anywhere.
What audio formats are supported?
BTR AMP plays a huge range of formats — MP3, M4A, M4B, MP4, AAC, FLAC, ALAC, AIFF, DSD (up to DSD256), APE, MPC, TTA, WV, OGG Opus, OGG Vorbis — plus M3U playlist files. That covers lossless, lossy, and hi-res audio at 96kHz/24-bit and beyond, and each track shows its exact codec details (e.g. “FLAC 2933kbps · 96kHz · 24-bit”). More formats are on the way.
Does BTR AMP play DSD files?
Yes. BTR AMP plays DSD audio from DSD64 up to DSD256 — bit-perfect DoP output to compatible USB DACs, or automatic high-quality PCM conversion on any other output, with settings you can tune per output device. DSD playback is a Pro feature.
