ListenBook

An audio player for those who really listen

ListenBook plays your audiobooks, lectures, podcasts, and voice memos—whatever you have in your files.

Works on iPhone, iPad, in the car via Apple CarPlay, and on Apple Watch—and now on the watch for real: you can transfer a book via Bluetooth, leave your phone at home, and go for a run. When you return, the playback will resume on your iPhone right where you left off.

Formats

MP3, M4B, M4A, AAC, FLAC, Opus, Ogg, WMA, AMR, AWB. Chapters from M4B, ID3 tags, and CUE sheets are parsed automatically. We don’t support DRM—only your own files. Audible AAX won’t work, and that’s by design.

How to add a book

AirDrop, Files, Finder/iTunes, Wi-Fi via browser, WebDAV, direct link, entire ZIP archive, audio extraction from YouTube and Vimeo. It also features a built-in search for LibriVox—thousands of audiobooks that are already in the public domain and free.

Audio

Speed from 0.5× to 5× with memory for each book—different authors have different speaking tempos, and the app remembers this. Volume boost for quiet recordings. Noise reduction with five presets for different conditions (from a lecture in a noisy auditorium to speech in silence). 10-band equalizer. Binaural processing so your ears don’t get tired during long headphone sessions. Voice tone adjustment.

Sleep Timer

The volume fades out smoothly at the end—no abrupt cutoff. If you haven’t fallen asleep yet and tap the earbud button, the timer restarts. You can set it to “always on” so you don’t have to reset it every night.

Widgets

Five options: three styles for the home screen, one for the lock screen (round and rectangular), and one for the Control Center in iOS 18. Open your current book with a single tap.

Apple Watch — without an iPhone

Transfer the book to your watch once — and you can listen offline. Adjust the volume with the crown, flip through chapters, and access the sleep timer and playback speed right from your wrist. Progress syncs both ways when the devices are near each other again.

What Else You Should Know

Bookmarks are grouped by book. The event history shows exactly what paused playback if the position was “lost.” Listening statistics—by day, week, month, and all-time. Cover art search, repeat mode, and shuffle for language practice, plus a separate music mode.

ListenBook doesn’t sell anything itself. It’s just a player. The content is yours.
