UniReader 1.16.2 UniReader opens what other apps refuse. PDF, EPUB, DjVu, CHM, MOBI, AZW3, PRC, FB2, LIT, CBZ/CBR, DOC, DOCX, RTF, TXT and Markdown: 15 formats in one library. No more juggling apps. --- READ WITHOUT FRICTION --- The real problem isn't reading. It's everything that interrupts it: the wrong format, an awkward import, a lost page. UniReader exists to remove that friction. Open. Read. Pick up exactly where you left off. --- WHAT YOU GET --- A real library 20 books or 20,000: the library stays fast and organized. Grid or list, covers, folders, collections, search. Filter by format and import over your local network. Comfortable reading Light, Night, Sepia and Paper themes; adjustable fonts and margins. EPUB in two columns, PDF full screen, your exact place restored. Markdown, read and written Markdown files open fully formatted: headings, tables, task lists, syntax-highlighted code, footnotes and formulas, in your reading theme. Create a new document in any folder and write it in the app. Serious annotations Highlights, bookmarks, handwritten notes, export to PDF or PNG. Optional cloud sync for your progress and bookmarks. Catalogs and import OPDS catalogs (Gutenberg, Wikisource and more), import from a browser on the same Wi-Fi network. Shortcuts actions, and your books show up in system search. --- WHO IT IS FOR --- For anyone with hundreds of books in ten formats who just wants to read them. For the person who annotates technical manuals in the morning and novels at night, and refuses to run two separate apps. For researchers, students and avid readers: anyone who reads seriously and wants a tool that keeps up. --- ACCESS --- Free plan DRM-free PDF, EPUB and TXT reading, plus the first 7 pages of FB2 books, with the essential library tools. Free forever: try it with no commitment. Premium Every format, cloud sync, advanced annotations, reading statistics and sync with UniReader on your computer. Try Premium free for 10 days: you won't be charged when the trial ends. --- PRIVACY --- Your documents stay on your device. No account required, no server. No tracking, no analytics, no data collection. UniReader doesn't know what you read. By design. Less friction. More reading.
