Is Lectern free?
No. Lectern is a one-time purchase of €2.49 (price varies by country), with no ads and no in-app purchases. You buy it once and it's yours.
Does it really work offline?
Yes. Reading, the read-aloud voices, highlights, the dictionary and your library all work with no connection. The only time it goes online is for an optional catalog or sync that you set up yourself.
Can it read books out loud?
Yes, using on-device voices: your system's, plus higher-quality Piper and Kokoro neural packs. It highlights the sentence it's reading, plays narrated EPUB3 books, and can run ambient sound and a sleep timer.
Can it read PDFs aloud?
Yes. Lectern reflows text-based PDFs into flowing text, then reads them aloud with the same on-device voices. Scanned, image-only PDFs have no text layer, so they can be viewed but not read aloud.
Can I play my own audiobooks?
Yes. You can link your own M4B or MP3 audiobook to a book, and Lectern also follows EPUB3 Media Overlays for professionally narrated titles.
What can it open?
EPUB and EPUB3, PDF, MOBI and KF8, FB2, plain text, and CBZ, CBR and CB7 comics, including fixed-layout books.
Can I sync between devices?
Yes, through a folder you control on Google Drive, Dropbox, OneDrive or Nextcloud. Your reading position, bookmarks, highlights and ratings stay in step across devices, with no Lectern account or server in between.
Does Lectern show ads or track me?
No. There are no ads, no analytics and no tracking of any kind. Your books, highlights and reading statistics stay on your device.
Which devices does it run on?
Android phones and tablets, and it behaves well on e-ink devices thanks to a reduce-motion option and calm defaults.
Is it good for dyslexia or e-ink?
Yes. OpenDyslexic is built in, there's a one-tap Dyslexia preset, and a reduce-motion option keeps things calm on e-ink screens.
Can I import my Kindle highlights?
Yes. Lectern can import your Kindle highlights from a “My Clippings” file, and can export your highlights to Markdown or JSON.
Is Lectern open source?
No. Lectern is a paid, closed-source app made by Hofstack. It uses some open components (such as Piper / sherpa-onnx voices) but the app itself isn't open source.
How is Lectern different from ReadEra, Moon+ Reader or Librera?
Lectern focuses on high-quality on-device read-aloud (neural Piper and Kokoro voices), an ebook-and-audiobook combo, faithful typography and account-less sync, with no ads at any tier. See the full comparison.
What languages is it in?
The app is translated into English, Dutch, German, French, Italian, Arabic, Chinese, Japanese and Hindi.
Where can I read Lectern's privacy policy?
On the privacy page. In short: no servers, no accounts, no ads, no tracking. Your data stays on your device.
