# Which Audiobookshelf app for iPhone? Nine apps compared

No single app fits everyone. Pick by streaming, podcasts, Apple Watch, other servers and price.

Checked 2026-10-26. Canonical page: https://justread.app/en/compare/audiobookshelf-iphone-apps

## Which should you pick?

- **Absorb**: you want a free, open-source app that streams or downloads, with no ads.
- **AudioBooth**: you want an Apple Watch app, CarPlay and several servers in a free app.
- **BookPlayer**: you also play audiobook files from your phone, in the same app.
- **plappa**: you also run Jellyfin or Emby. Downloads cost $4.99 once or $1.99 a year.
- **Prologue**: you use Plex too and want one library for both.
- **ShelfPlayer**: you run many servers and will pay a subscription to listen offline.
- **SoundLeaf**: you want an Apple Watch app, CarPlay, podcasts and an ebook reader, with playback free.
- **Still**: you want OpenID sign-in, an Up Next queue and an ebook reader in a free app.
- **justRead**: you want audiobooks, ebooks and comics in one library, and your iPhone cannot run iOS 26.

## Why you need a third-party app

Audiobookshelf is a free, open-source server for books and podcasts. Its own iPhone app is still a beta.

The project's README, read on 26 October 2026, says the TestFlight beta is full.

So independent apps filled the gap. This page compares nine of them:

- Seven are built just for it.
- One is a general audiobook player that added it.
- The last is a reader that also connects: justRead.

Comparing one app with justRead? Start with [justRead vs BookPlayer](https://justread.app/en/compare/justread-vs-bookplayer).

## How justRead works with Audiobookshelf

justRead is a reader first, so it downloads the books from your server.

Sign in with a password or your server's OpenID. Pick a book and it downloads into your library, then plays from the device. It does not stream.

- Downloads run in the background and follow your account's download permission.
- Your place and finished status sync both ways.
- Ebooks download too, and a book's audio and ebook copies are linked.

## Where justRead loses

Seven places where another app here is the better choice.

### It does not stream

justRead plays a downloaded copy. Absorb says it streams, and five more apps mention it. If your connection is slow, pick one of them. [1][9][11]

### It leaves podcasts out

Only book libraries are listed. Six other apps list podcasts, so a server with shows suits them better. [1][2][13][4][9][10]

### There is no Apple Watch app

Six other apps list one. Four say you can listen without the phone nearby. [1][13][8][6][11][12]

### It connects to no other server

justRead has no link to Jellyfin, Plex, Navidrome or Subsonic. Three other apps cover Plex, Jellyfin or Emby. [1][6][4][11]

### No volume boost or equalizer

Six other apps list a boost, an equalizer or both. It helps with quiet recordings. [1][13][6][8][9][10][11]

### You pay after 14 days

Absorb, AudioBooth and Still are free. The trial covers the whole app, then a paywall blocks it. [1][9][8][10]

### Fewer people have rated it

justRead has 54 US ratings at 4.61. Prologue has 5,826 at 4.85, and BookPlayer 19,795 at 4.84. [19][6][11]

## Where justRead is the better fit

Five reasons you may prefer it.

### Audio, ebooks and comics together

A book's audio and ebook copies are linked. The library also holds EPUB, PDF, CBZ and CBR, with an Audio filter. [1]

### It installs on older iPhones

justRead 5.5 needs iOS 18.1. Three other apps need iOS 26.0 or later. [19][2][11][6]

### Your files and your server

justRead plays files you add yourself as well as books from your server. Among the others, only BookPlayer says the same. [1][11]

### Downloads follow your server's rules

Downloads respect your account's download permission and run in the background. We found no such mention for other apps. [1]

### Read Aloud

For a book with no recording, Apple or neural voices read it to you, even in CarPlay. The other apps' pages describe no text to speech. [1][13][6][8][9]

More on the [audiobook player](https://justread.app/en/audiobook-player) and the [ebook library](https://justread.app/en/ebook-library).

## How to switch apps without losing your place

Your place lives on your server, so switching mostly means signing in again.

### Pause once in the old app

Pause with a connection, so your last position reaches the server. [2][8][10]

### Sign in as the same user

Position belongs to the user, not the app. Using OpenID? Check the new app lists it. [2][13][6][10][1]

### Download your books again

Each app keeps downloads in its own storage, so download the ones you plan to hear. 

### Check your place, then keep both

Compare the chapter and time with where you stopped. Remove the old app after a week of steady listening.

No. justRead downloads a book and plays the copy from your device. That suits offline listening, but a book must finish downloading before you can play it. [1]

plappa is free to install, but downloads cost extra. If you only use one server, Absorb, AudioBooth and Still are free. [4][5][9][8][10][11][6]

### What is a good Prologue alternative?

If you only use one server, AudioBooth and SoundLeaf are free and list an Apple Watch app. If you use Plex too, Prologue is the one that lists it. [6][7][8][13]

plappa adds Jellyfin and Emby. ShelfPlayer adds many servers, Siri and Live Activities. Jellyfin points to plappa, and many servers to ShelfPlayer. [4][5][2]

Grimmory has no iPhone app of its own. justRead opens single-file audiobooks from its server. [26][1]

### Is justRead only for Audiobookshelf?

## Try justRead with your Audiobookshelf server

Sign in with your password or single sign-on, download the books you want and listen offline. The 14-day trial covers the whole app.

## How we checked

justRead.app makes justRead, so we hold this page to a stricter rule than a neutral roundup. Every justRead cell comes from the app's source code at the 5.5 release.

The other eight apps' cells come from each app's US App Store listing, vendor site or public repository, all re-read on 26 October 2026.

"Not stated by the developer" means we found nothing either way and did not guess. We did not run the apps against a server, so a cell shows what the developer says.

Apps change often, and some ship an update every week. The dates tell you how old each fact is.

The quotes are examples, not a count. The ShelfPlayer and Prologue reviews come from samples pulled on 23 October 2026 (84 and 195 reviews). We re-read each quote in Apple's feed on 26 October 2026.
