Read,
undisturbed.
An EPUB and PDF reader that gets out of the way — then helps you keep what mattered. Highlights, a dictionary, spaced review and read aloud, all on your phone.
Free forever. Signed APK with a SHA-256 checksum on every release.
What vayana actually does.
12 featuresEPUB, PDF & paper
Import files, scan a folder, or use Open with. Duplicates caught on the way in; physical books tracked too.
A page set your way
Fonts (your own too), size, spacing, margins, hyphenation, tap zones, volume keys and two-column landscape.
Highlights that stay useful
Highlights, underlines, bookmarks and tagged notes. Import Kindle clippings, export Markdown, share quote cards.
A dictionary that works offline
Double-tap any word, save it to a review deck, and export vocabulary to Anki CSV or Markdown.
Highlights come back around
Review your passages on a spaced schedule — See soon, Got it or Know it well.
Read aloud that follows the text
Sentence by sentence, marked on the page, with any TTS voice, a sleep timer and lock-screen controls.
Library, shelves, read next
Currently Reading, shelves, series folders and a Read Next queue that respects series order.
Goodreads, when you ask
Preview, then apply covers, series, genres and descriptions. Popular quotes appear as dotted marks.
Search every word you kept
Full-text search across titles, tags, highlights and notes — keeping Malayalam and Indic words whole.
Stats computed on your phone
Reading time, sessions, streaks, daily and yearly goals, and how long each book took.
Sync without anyone’s server
A private GitHub repo you own; book files and covers encrypted with AES-GCM before upload.
Backups you don’t think about
Portable ZIP backups plus automatic daily, weekly or monthly backups to a folder you pick.
A real E-Ink mode, not a filter.
Pick E-Ink as the display profile and vayana changes how it behaves, not just how it looks — built for Boox and other paper-like Android screens.
Nothing that moves
No page-turn animation; a static progress squiggle; a clock that updates only on page turns.
Marks without colour
Highlight colours become solid black shapes — shaded, underlined, wavy, boxed.
Page keys everywhere
Hardware buttons turn pages in the reader and page through long screens elsewhere.
Screens, not scrolling
Library, Notes, Search and Settings move one screen at a time.
Clean refreshes
Clear ghosting every few pages, when the menu closes, and at each new chapter.
Ink-friendly type & covers
Bolder text, high-contrast greyscale covers, and solid borders instead of faint tints.
Honest scope: the E-Ink profile uses portable Android behaviour, so it works across devices. Vendor-specific refresh modes such as the Onyx Boox SDK aren’t integrated yet.
Your books, your device.
No account, no ads, nothing leaves the device on its own. The dictionary is bundled, stats are local, backups are plain ZIPs. Sync goes only to a private GitHub repo you own, with books and covers encrypted.
Make it yours.
Light, dark, true black or Material You. Paper, sepia, mint, sky and rose reader themes with warm-light controls. Bionic reading, bolder text, fullscreen and keep-awake — on phone, tablet or E-Ink.
“A good book asks for your whole attention. Vayana just makes room for it.”
വായന — Malayalam for reading.
