--- READ WITHOUT FRICTION ---
The real problem is not reading.
It is everything that interrupts it: wrong format, awkward import, lost progress.
UniReader exists to remove that friction.
Open it, read, and pick up exactly where you left off.

Comfortable reading

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
What's New 1.10.0
- Identify your books online: look a document up in Open Library and Crossref from its details, compare the proposals - cover, publisher, year, ISBN - and accept the right one.
- The details sheet now carries ISBN, summary and language.
- DjVu, CHM and MOBI open faster, the app is 45 MB lighter, and Microsoft Reader (LIT) books finally open.
- A reading position coming from the desktop app is restored properly - it used to reopen the book at the first page.
- DjVu: the page's text can now be selected as in a PDF - long-press a word, drag the handles, then copy, highlight or look it up. Zooming stays sharp and keeps its place.
- Word, FB2 and MOBI books open with their chapters and their table of contents.
- Fit to width now fills the screen edge to edge, dark pages no longer have a white band around them, and a text file reopens where you left it.
- Fixed a crash when opening some malformed EPUB files.
