Frequently asked questions

How do I add a book?

AirDrop a DRM-free file (.m4b or .mp3), share it into Narrhaven, or open it from the Files app. The app copies the file into its own library before playing. Audible DRM formats (.aax / .aaxc / .aa) are rejected on purpose — the app does not decrypt DRM.

Where is my listening position?

It is stored on your iPhone only, next to your library metadata. Deleting the app deletes every position and every imported book, unless you first back up your library (Settings → Back Up Library…) or restore from an iPhone backup that still has the app data.

How do I back up my library or move it to a new install?

In Settings, tap Back Up Library… and choose where to keep the file in Files. It is one .narrhaven file with your books, covers, tags, speeds, and listening positions; you can share it from Files, for example by AirDrop. On the other install, open that file, or tap Restore Library… in Settings and pick it. Everything comes across with the same IDs. Books already in the library are kept, and nothing is deleted. Large libraries take a while.

Lock screen and Bluetooth controls do nothing

Start playback once in the app so the system Now Playing session is active. Then play, pause, skip, and scrubbing work from the lock screen and from Bluetooth headphones. Narrhaven does not claim CarPlay on the App Store listing; device builds do not include the carplay-audio entitlement.

Compression

Swipe a title in the library and choose Compress to re-encode to mono AAC at 24, 32, or 48 kbps. Duration is preserved so every saved position stays valid. Chapters and cover art are unchanged because they live in the store, not in the audio file.
