Nightjar: Audiobook Player
M4B & MP3, offline and cloud
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Your audiobooks, wherever they live: on your phone, in the cloud or on your own server. Starts in seconds, works offline and remembers your place in every book.
Nightjar is an offline audiobook player for the M4B and MP3 audiobooks you
already own. There is no catalogue and no store inside — you point it at your
own files and it does the rest.
YOUR STORAGE, NOT OURS
Files on the device, Dropbox, OneDrive, Google Drive, or a WebDAV server:
Nextcloud, Yandex Disk, pCloud, Koofr, Icedrive, Box, Synology and others.
STARTS IN SECONDS
Books stream as you listen — playback begins as soon as the first piece
arrives, whether the book runs one hour or twenty. Jumping back to re-hear a
passage or skipping ahead pulls just that spot, so you never wait for a full
download. What you have heard stays on the phone for next time.
OFFLINE WHEN YOU NEED IT
Download a book for the flight, pause and resume it, and free the space again
with one tap.
EVERY WAY TO GET BOOKS IN
Share or AirDrop from other apps, whole folders from the Files app, the app's
folder in Finder on your Mac, transfer from a computer over Wi-Fi, or a direct
link to a file of your own. ZIP archives are unpacked right on the device.
Point at the top of a collection and Nightjar walks the tree: an m4b is one
book, a folder of chapters is one book, multi-disc folders become volumes.
BUILT FOR LONG LISTENS
Chapters and bookmarks, playback speed, sleep timer, precise resume,
lock-screen and headphone controls.
FORMATS
Plays directly: MP3, M4B, M4A, AAC, WAV, FLAC. M4B keeps its chapters and
cover. MKA and MKV are repacked on the device without re-encoding, so nothing
is lost in quality.
Not supported: OGG, Opus, WMA, and any DRM-protected file — including
Audible AA and AAX. Nightjar plays DRM-free files only.
THEMES AND BACKUPS
Handcrafted light and dark themes, and a daily local backup of your listening
progress that you can restore or export.
PRIVACY
No account to create, no ads, and no tracking: no analytics, attribution or
measurement SDKs, no usage statistics and no behavioural events. Only two things
reach us: a crash report when the app fails — you are asked about it on first
launch and can switch it off at any time — and, if you buy Pro, an anonymous
record of the purchase. Your passwords and access tokens stay in the device
keychain, and your books are fetched straight from your storage to your phone —
we run no server and never see your library.
FREE AND PRO
Everything local is free: the full player, every way of importing, Wi-Fi
transfer, and the base themes. Pro adds cloud sources, offline downloads and
the extra themes, as a monthly or yearly subscription or a one-time lifetime
purchase, with a 7-day trial. Subscriptions renew automatically until
cancelled in your App Store account settings.
