With self hosted Kavita and the two way progress sync its incredible. Setup was super easy and I’ve had zero issues thus far. I can only assume most of the issues people will have is not due to this app but with whatever server they’re trying to connect to. Love the app, highly recommend. ### 5/5 — Read more books. *2026-08-28* I tried a fair dozen different reader apps. Sutra was the hands down winner. From ease of connecting to servers to the visual presentation of individual books: high marks all around. Easy choice to pay for the full Monty; gimme those comics, yes please! ### 4/5 — Display of pdf *2026-08-18* Another comment: for pdf richely designed, i.e. with pictures, frames, etc. there should be an option to display the original pdf as-is, without rendering it’s text independently from the original design. Comment because some pdf aren’t really readable because of this rich design which is difficult to handle **Developer response:** Thanks for the feedback! I'll look into full white characters for a dark theme as an option. To your other question, I'm trying to create an option for users to open a couple of cbz files as a part of the free offering so that they can test out the feature as a part of the 2.1 release ### 1/5 — Calibre web support broken *2026-08-08* I have tried several times now to get my Calibre web library working but it just hangs. I’ve done so much troubleshooting on my server to try and diagnose why it doesn’t work. I can put in my server details and it recognizes my library but just never returns. If I ever get it working maybe I can see how well it actually works as an OPDS client. Komga support is also welcome and interesting but I’m not paying money if I can’t get the basic functionality working. **Developer response:** Sorry to hear that! I would appreciate it if you could submit feedback here with your specific issue, and I will take a look to see how we can fix it - https://sutra-reader.com/feedback.html ### 5/5 — Amazing reading experience *2026-08-06* This is a solution for all your e reading problems. Loving the ability to link to Kavita and Gutenberg. And the reading experience has been fantastic. Takes a bit to load my library, but is great after that. ### 5/5 — Smooth *2026-08-04* I like that it is easy in use. Also that it is free. Thanks to the app I did setup my own calibre( i will test it for 1-2 weeks and definitely support. Even if I don't need that extra options). Maybe we can get a Google translator. ### 4/5 — Handling of epub full pages should be improved *2026-08-04* The application is great, in particular it’s ability to connect to Calibre and Kavita servers. However, the display of epub pages is weak and could be improved. The page does not fully occupy the full display of an iPad Furthermore when you choose a dark theme full white characters could be enabled to enhance contrast You should also allow one import of cbz file so that one can test your display of a comic, before buying the pro version **Developer response:** Thanks for the feedback! I'll look into full white characters for a dark theme as an option. To your other question, I'm trying to create an option for users to open a couple of cbz files as a part of the free offering so that they can test out the feature as a part of the 2.1 release ### 5/5 — Finally got https running *2026-07-17* https was incredibly hard to figure out but once the setting were ther this app works like a charm 5 stars **Developer response:** Thank you!! ### 5/5 — Very nice *2026-07-14* Very good app, I can't wait to see how it evolves. The developer is responsive and very nice, the update with the page curl animation is lovely. Thank you ! **Developer response:** Thank you!! ### 5/5 — Very good *2026-07-14* Great integration with kavita. It is the only OPDS app Ive seen that will load in my epub comics **Developer response:** Glad to hear that. Thanks for your review! ## Frequently asked questions about Sutra ### What is Sutra?

Reading Statistics A new Stats tab: time read, streak, a swipeable activity chart, and your reading progress across every book in one place. WebDAV Server Support Browse and download EPUB/PDF files straight from a WebDAV server — Synology, and any other WebDAV host — with self-signed certificates supported via a one-time trust prompt. Manga Support Read comics right-to-left, top-to-bottom — tap left to advance, tap right to go back, and panel order flows top-right to bottom-left. Switch any comic between Regular and Manga from the reader's Aa menu; it's remembered per book. Comic panel detection now has dedicated tuning for manga-style pages, on top of general improvements to how accurately panels are cropped for every comic. Tons of Fixes and Improvements Smoother, more accurate continuous scrolling that reliably resumes exactly where you stopped, easier connectivity to self-hosted servers without HTTPS configured (with clearer guidance for Tailscale and similar VPN setups), faster and more reliable loading for large libraries, more accurate comic panel detection across the board, and a fix for books occasionally opening to a blank page.

Here's what's new in Sutra: Read Comics Panel by Panel A brand new way to read comics: Sutra detects each page's individual panels, and a tap or page-flip advances panel by panel instead of jumping the whole page at once — every close-up lands exactly where the artist intended. Works on CBZ, PDF, and fixed-layout comic EPUB/MOBI, and it's free for everyone, no purchase required. Just Your Files — No Server Needed Already have a folder of books or comics? Import EPUB, PDF, CBZ, or MOBI files straight from the Files app — no self-hosted server, no account, no setup. Import a whole folder at once and Sutra grabs real covers and metadata automatically. Komga Support Komga is now a first-class server type alongside Kavita and Calibre, with the same page-accurate two-way progress sync Kavita users already love — read your Komga comics and manga panel by panel too. CBZ Comics Open .cbz comic archives in a fixed-layout, zoomable page reader — and read them panel by panel just like everything else. DRM-Free MOBI Support Import your .mobi files straight from the Files app and read them right in Sutra. Sutra Pro A friendly one-time purchase — no subscription, ever — that unlocks Komga libraries, CBZ comic reading, and DRM-free MOBI books. EPUB, PDF, local file imports, and Panel Mode itself stay free forever, as always. Thanks for reading with Sutra — happy reading! ### 1.3.0 — 2026-07-16 Mark Your Books with Color-Coded Highlights Select any passage in EPUB or PDF, choose a color, and it highlights persistently while reading. Every highlight auto-saves to Settings → Text Highlights and syncs via iCloud to all your devices. Tap a highlight to change its color or delete it. Browse all highlights for a book directly in the reader's Bookmarks sheet. Improved Definition Lookup No more automatic pop-ups when you select text. Now you control what happens: tap Define for the definition, Highlight to mark it, Copy to save it, or Search the library — all in one convenient menu bar. Your Series, Organized Automatically If your Kavita or Calibre server has series metadata, Sutra groups your books by series in the Collections shelf — so you can browse and pick up the next book without losing your place in a sequence. ### 1.2.0 — 2026-07-10 A big update: a real page-curl animation for turning pages, a full dark theme (Day, Night, or follow System), and Left-Handed Page Turns for one-handed reading — all new in Settings. Series information now comes through from Kavita libraries, with a proper Series sort. Standard Ebooks connects with your Patrons Circle email. Plus a wide pass of reliability fixes: more accurate cross-device and Kavita progress sync, large self-hosted libraries no longer silently losing books from search, and a range of smaller fixes across search, downloads, and the reader. ## Related topics [sutra](https://appshunter.io/ios/topics/sutra) · [kavita](https://appshunter.io/ios/topics/kavita) · [decimal reader](https://appshunter.io/ios/topics/decimal-reader) · [kopi 8 port charge current reader](https://appshunter.io/ios/topics/kopi-8-port-charge-current-reader) · [automatic reader](https://appshunter.io/ios/topics/automatic-reader) · [opds](https://appshunter.io/ios/topics/opds) · [gazzetta reader](https://appshunter.io/ios/topics/gazzetta-reader) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
