How to listen to M4B audiobooks on iPhone
M4B is the usual file format for audiobooks you own: from a DRM-free store, a CD you ripped, or a public-domain site like LibriVox. It's one file with chapter markers inside. iPhone can play it, but not very well on its own.
1. What iPhone can do on its own
- The Files app plays an M4B or MP3 if you tap it, but it's a simple preview: no chapters, no sleep timer, and it doesn't remember where you stopped once you close it.
- Apple Books can play audiobooks you add to Books on a Mac and then sync to your iPhone with a cable. It works, but every new book means a trip to the computer.
2. Use an audiobook player that reads your files
An audiobook player can open the files right where they are, in iCloud Drive or on your iPhone, and treat each one like a book: chapters, your place, speed and a sleep timer.
We make one called Storyhour. It reads the chapter markers inside M4B, M4A and MP3 files, and turns a folder of MP3 parts into one book with each file as a chapter.
- Put your audiobooks in a folder in iCloud Drive or On My iPhone (with the Files app, or from a Mac).
- Install Storyhour and choose that folder. Storyhour plays the books from there: no converting, no copying.
- Tap a book. It remembers where you stopped, and the scrubber moves within the chapter, so a slip of the finger can't throw you hours off.
It's free for any 3 books with every feature; your whole library is $4.99 once, for your whole family. No subscription, no ads, and no account.
Good to know
- Audiobooks bought from Audible or Apple Books are protected (DRM), so no other app can play them. These steps are for files you own.
- A book in several MP3 files works best as one folder per book, with the files numbered in order.
- Your place in every book is saved in iCloud, so it comes back on a new iPhone.
