UniReader
Read full descriptionHide full description
UniReader 1.15.0 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 and EPUB reading, 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.

Eluna Reader

No subscription. No ads. No account. No AI. Eluna Reader opens almost any book or document — over 20 formats — and keeps every page, note and bookmark on your own device. Most reading apps rent you your own library. Eluna never does: reading is free, the only purchase is a one-time tip that unlocks nothing, and anything you write stays yours. READS 20+ FORMATS EPUB (2 & 3), FB2, FB3, MOBI, AZW3, PRC, PDF, DjVu, DOC, DOCX, ODT, RTF, TXT, Markdown, HTML, CHM, UMD and comics (CBZ, CBR, CBT) — even books inside ZIP archives. One shelf for novels, manga, manhwa, textbooks and PDFs alike. READ-ALOUD & REAL PAGE NUMBERS Listen to any book with the built-in read-aloud voice, the current sentence highlighted as it speaks. See real page numbers — "page 128 of 512" — not just a percentage, in a status bar you assemble yourself. TYPESET IT YOUR WAY Paged mode with slide, fade and 3D page-turn animations, or a smooth continuous scroll. Portrait or landscape, two-page spread on a tablet. 5 bundled fonts including OpenDyslexic, or import your own TTF/OTF. Fractional font size, four independent margins, line and paragraph spacing, hyphenation. Keep the publisher's own CSS, or force your own styling on top. NOTES THAT LEAVE THE APP Highlight in many colors, tag notes with hashtags, pin and group them into a second brain. Export the whole library to Markdown, Obsidian, Readwise, JSON or CSV — and import it back. Your annotations belong to you, not to a database. SYNC WITHOUT AN ACCOUNT Reading position, highlights, notes and reading statistics stay in step across iPhone and iPad through your own iCloud — encrypted end to end, no server, no sign-up. Speak KOReader's sync protocol (KOSync) or point it at your own WebDAV folder to plug into Kavita, Komga or Calibre-Web. FIND ANYTHING Full-text search across every book, inside PDF pages, and through all of your notes at once. On-device OCR reads scanned PDFs so even they become searchable — nothing is ever uploaded. BUILT FOR LONG READING Automatic day and night, sepia, OLED-black and e-ink themes. Blue-light filter, on-screen reading ruler, brightness control and auto-scroll. Remap tap zones, swipes and the volume keys. Dictionary and translation on any word — strictly opt-in. Browse OPDS catalogs and your own servers. PRIVATE BY DEFAULT Works fully offline. No trackers, no telemetry, and no AI trained on your books. Optional Face ID / Touch ID lock and screenshot protection. Every connection the app can make is listed on a single screen. 61 LANGUAGES, 63 BADGES The whole app is translated into 61 languages. Reading statistics, daily streaks and 63 achievement badges keep the habit going. Eluna Reader — a power reader that respects your library and your privacy.
