Sutra — the app to read all your DRM-free content. Connect your Kavita, Calibre, Komga, or WebDAV server, any OPDS catalog, or Project Gutenberg's full public-domain library. Load local files, read manga and comics panel by panel, track your reading stats, and auto-scroll through long reads.
Connect Kavita, Calibre, Komga, Grimmory, or any OPDS server, plus WebDAV hosts like Synology. Everything works on your local network with no cloud middleman, and self-signed certificates need only a one-time trust prompt.
Project Gutenberg's 75,000+ public-domain classics and Standard Ebooks' typeset collection, no server required. Gutenberg is offered right in first-run setup, and search is more reliable, with duplicates removed. Patrons Circle sign-in unlocks the full Standard Ebooks catalog.
Sort by Recently Read, Title, Author, or Date Added. Books with no artwork get a clean title-and-author cover instead of a blank tile.
Series appear as grid tiles, and books from the same series stack with a count. Collections open in a consistent grid, and you can rename your own. Favorites is built in, always first, with its own heart-marked card.
Authentic page-curl, rich typography controls, five reading themes including high-contrast Contrast, and in-book search. There's a two-panel facing-page spread on iPad, and you can dim just the reader from the Aa menu without touching system brightness.
Sutra reads panels one at a time, with full right-to-left manga mode. CBZ streams straight from Komga and Kavita, and upcoming pages are prepared ahead of time, so page turns feel instant. Switch any book between Regular and Manga from the Aa menu.
Set your pace and let the page flow. Swipe up or down to adjust speed on the fly, or tap to pause and resume. Perfect for hands-free reading.
Open EPUB, PDF, CBZ, and MOBI files from your Files app, AirDrop, or any share sheet. No server required.
Highlight in color and double-tap a word to define it. Tap a footnote and it opens in a sheet, so you never lose your place. Highlights and lookups sync via iCloud.
iCloud syncs position, bookmarks, and highlights across your devices. Kavita and Komga sync is page-accurate, and finishing a book syncs back to your server too.
A Stats tab tracks time read, your streak, a swipeable activity chart, and progress across your library. Time-remaining estimates learn your reading speed for each format.
Every CBZ comic and comic-shaped MOBI book opens with a free 7-page preview — read the first 7 pages of anything in your library before deciding whether to unlock Sutra Pro.
Sutra works with files you own outright — no DRM, no lock-in. We've put together a curated list of stores and publishers that sell ebooks the right way: you pay, you download, you keep the file forever.
