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, installed voices, highlights, the dictionary and your library all work with no connection. Lectern only goes online when you ask it to: downloading a voice, browsing a catalog, looking up book info or covers, or using your own speech server.
Can it read books out loud?
Yes, using on-device voices: your system's, plus higher-quality Piper, Supertonic and Kokoro neural voices you download once. 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 can reflow text-based PDFs into flowing text and read them aloud, or read over the original pages with the spoken sentence marked. Scanned, image-only PDFs have no text layer, so they can be viewed but not read aloud.
Can I play my own audiobooks?
Partly. You can link one M4B or MP3 file to a book in your library and play it there, with chapters for M4B. Lectern also follows EPUB3 Media Overlays for professionally narrated titles. Audio files on their own don't appear in the library.
What can it open?
EPUB, EPUB3 and KEPUB, PDF, MOBI, AZW3 (KF8), AZW and PRC, FB2 and FBZ, plain text, and CBZ, CBR, CB7 and CBT comics. Image-based fixed-layout EPUBs open page by page; text-based ones are reflowed.
Can I sync between devices?
Yes, through a folder in your own cloud. Google Drive is tested, and you can use any cloud app that shows a folder in Android's file picker, such as Dropbox, OneDrive or Nextcloud. Your reading position, bookmarks, highlights and ratings stay in step across devices, with no Lectern account or server in between. Book files don't sync, so each device needs its own copy.
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 8.0 or newer, on phones and tablets. On e-ink devices a dedicated e-ink mode, detected automatically on many devices, keeps things calm.
Is it good for dyslexia or e-ink?
Yes. OpenDyslexic is built in, there's a one-tap Dyslexia preset, and a dedicated e-ink mode 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, Supertonic and Kokoro voices), reading and listening in one app, 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, Hindi and Indonesian.
Where can I read Lectern's privacy policy?
On the privacy page. In short: no servers of ours, no accounts, no ads, no tracking. Your data stays on your device unless you send it somewhere yourself.
