Best Audiobook Player Apps for Your Own MP3 and M4B Files

BookPlayer is “a wonderful player for your M4B/M4A/MP3/FLAC based audiobooks”: chapters, speed, smart rewind, a volume boost, an adjustable sleep timer, CarPlay, VoiceOver, an Apple Watch companion that plays on its own, and Cloud Sync across devices. It’s free with in-app purchases, and open source under the GPL.¹

• Adding books: AirDrop from a Mac or another iPhone, open from the Files app, use File Sharing in Finder or iTunes, import a ZIP of folders, or connect your own Audiobookshelf or Jellyfin server.¹

Apple Books has chapters, narration speed and a sleep timer built in.² Your own audiobooks get there from a Mac: import them into Books, then sync audiobooks to the iPhone in Finder.^3,4

Prologue plays the books on your Plex or Audiobookshelf server (“It doesn’t sell books or come with any of its own”), with downloads for offline listening, a sleep timer to the end of a chapter, bookmarks with notes, CarPlay and Apple Watch, and it now runs on Android 15 or later too. It’s free, with a one-time Premium unlock.^5,6

Android plays AAC and MP3 natively, so any of these opens an M4B.¹⁷

• Voice: “a clean audiobook player for people who bring their own books.” Add a folder once; it plays M4B, MP3, M4A, OGG and Opus with a sleep timer that fades out or stops at the end of a chapter, skip silence, bookmarks and Android Auto. No account, no ads, every feature free; open source under the GPL.⁷
• Listen Audiobook Player: a paid app (“No in-app purchases to unlock features”) with the deepest controls: 0.5× to 6× speed, pitch, silence trimming, noise reduction, levelling, an equaliser, embedded chapters, its own sync, and downloads from Plex and Audiobookshelf. Android Auto too.⁹
• Smart AudioBook Player: put each book in its own subfolder of a “My Audiobooks” folder. Speed, bookmarks, a character list, a pause if you fall asleep, Chromecast. The full version is free for 30 days, then a one-time purchase; no ads.⁸

Windows has no audiobook player as good as the phone apps. Your choices:

• A browser player. Ours opens M4B and MP3 books with chapters, speed, a sleep timer, bookmarks and your place in each book, and installs as an app.
• VLC, free, plays M4B and has a chapter menu (Playback, Chapter), but it’s a media player: it won’t keep a place in each of your books.^13,14
• Audiobookshelf in a browser, if you run its server.¹⁰

• Apple Books: choose File, Import to add an audiobook; Books also syncs them to your iPhone through Finder.^3,4
• A browser player or VLC, as on Windows.¹³
• BookPlayer’s iPad version is in the App Store for Macs too, but its developer marks it “not verified for macOS”.¹

Cozy is a desktop audiobook player on Flathub: it plays DRM-free MP3, M4B, M4A, FLAC, OGG and WAV, remembers your position, has a sleep timer and per-book speed, and can keep a copy of a book on your drive while your library lives on a network share.¹² VLC and browser players work too.

A browser player needs no install on any computer, Chromebook or phone. Ours reads an M4B’s chapters and cover or a folder of MP3s as one book, remembers your place and speed per book, has a sleep timer that can stop at the end of a chapter, bookmarks, and lock-screen controls, and installs to play offline. Files stay on your device.
