Sutra — eBook Reader

Sutra is the best way to read your books and comics — all of them, in one beautifully simple app.

Drop in your own EPUB, PDF, CBZ, or MOBI files — no server, no setup, no account. Or connect Kavita, Calibre, Komga, any OPDS catalog, Project Gutenberg's 75,000+ free classics, or Standard Ebooks' curated collection. However your books and comics reach your phone, Sutra reads them all beautifully, panel by panel where it counts, with everything backed up and synced along the way.

READ COMICS PANEL BY PANEL • Sutra detects each comic page's individual panels and reads them one panel at a time — a tap or page-flip advances to the next panel instead of jumping the whole page at once, so every close-up and every punchline lands exactly the way the artist drew it • Works on CBZ, PDF, and fixed-layout comic EPUB/MOBI • Falls back gracefully to the full page on any page where no panels are detected, so nothing is ever unreadable • Panel Mode itself is completely free for everyone — no purchase required

JUST YOUR FILES — NO SERVER REQUIRED • Already have a folder of EPUBs, PDFs, comics, or MOBI files? Import them straight from the Files app — no self-hosted server, no account, no internet connection needed • Import a whole folder at once, covers and all — Sutra pulls real cover art and metadata straight from each file automatically • Everything lives right on your device, ready to read anywhere, anytime

THE READING EXPERIENCE YOU DESERVE • Gorgeous EPUB and PDF reading with an authentic page-curl you can tap or drag like turning a real book • Rich typography control: fonts, size, line spacing, alignment, bold text • Four carefully-designed reading themes to match your mood • Bookmarks, in-book search, and color-coded highlights that sync via iCloud • Full-screen reading, offline downloads, and progress syncing across devices

MARK YOUR PASSAGES • Select text and highlight it in four colors — all synchronized via iCloud • Search your highlights across all books from Settings or the reader • Change colors or delete anytime — highlights stay in sync everywhere

EVERYTHING IN SYNC • Kavita and Komga libraries: page-accurate progress syncs both ways with your server • iCloud: reading position, bookmarks, highlights, and looked-up words all sync automatically across iPhone and iPad • Automatic: no setup needed, no manual backups, works offline

PERSONALIZED READING • Day, Night, or System appearance — a real dark theme for the whole app • Left-Handed Page Turns for comfortable one-handed reading • Reduce Motion support and accessibility-first design • Favorites, collections, and smart sorting (by series, date read, title) • Storage manager to free space with one tap

BUILT FOR SELF-HOSTERS TOO • Connect any OPDS server: Kavita, Calibre, Komga, Grimmory, Booklore, or your own • Series from Kavita or Calibre auto-group into browsable Collections — perfect for long fantasy or sci-fi runs • Works with local network servers — no cloud storage, no middleman • Search all your libraries at once or narrow down to one

SUTRA PRO — UNLOCK THE FULL COLLECTION (optional, one-time purchase) • Komga libraries with native, page-accurate progress sync — read your comics and manga collection panel by panel, right where it's hosted • CBZ comic reading in a fixed-layout, zoomable page reader, panel by panel • DRM-free MOBI books — import your existing library (no DRM) straight from the Files app and read it in Sutra • One purchase, yours forever — no subscription, ever, no strings attached
