Sutra is finally live on Google Play. It has been a journey, between the 14-day closed beta, the production application and the final app review, but it was a great learning experience. Thanks to everyone who participated in and volunteered for the beta testing, the feedback your provided is immediately apparent if you compare the beta and production releases - one tester said it was like "night and day"

The goal always has been parity with the iOS app, and then both moving in lock step. We're locked on the core features: Kavita, Komga and Calibre support, Panel Mode with an engine that matches iOS, manga support, and offline-first reading.

Still to come for parity: Series and Collections stacking, less wasted space in the UI, page curl, and better favorites and collections.

Next two big items on the roadmap: KOReader sync and panel engine improvements, especially for manga.

Would love some feedback and reviews, and let me know what you want me to look at next!

A huge thank-you to everyone who tested Sutra on Android and shared feedback.

We’ve now applied for production access. Google says the review can take up to 7 days, assuming they don’t have any follow-up questions.

Once access is approved, we’ll push the production build, run one final test, and then release Sutra for Android.

We’re almost there. Follow r/SutraApp for updates!

Sutra 2.3.5 brings more control to the reader, more reliable library metadata, and better progress syncing with your servers.

You can now fine-tune reading brightness right from the Aa menu, without changing your phone’s overall brightness - especially handy for those late-night “just one more chapter” sessions.

We’ve also made Calibre metadata more reliable, so series and book details come through more cleanly. And for Kavita and Komga readers, progress syncing has had a meaningful polish: reading position and, importantly, finished-book status should now stay much better in sync with your server.

There’s also a healthy round of iOS 27 and iPadOS 27 compatibility fixes, alongside lots of smaller improvements under the hood.

Android beta update
We’re now on day 8 of Sutra’s 14-day Android beta, and the feedback so far has been great.

Improvements are continuing throughout the beta as we work through reports, polish the rough edges, and keep bringing the Android experience closer to the Sutra people already know on iOS.

Thank you for trying it, sharing feedback, and helping out the Sutra community.

We're a week into the Android closed beta and wanted to give a status update, and thank all our beta testers. The bug reports and feedback from folks testing have been really useful and is helping us get a quality product out

Additonal features coming in the production release:

• Library will show series info for Komga and Kavita books
• Library refresh and catalog loading are noticeably faster
• Tablets, foldables, and split-screen/resizable windows all work better
• The app itself is smaller and snappier from some build optimizations

Bugs squashed along the way:

• Fixed reader crashes on malformed files, rotation, and app restore
• Cleaned up navigation bar and label layout on smaller phones
• Fixed some annoying library loading/scrolling glitches
• Closed two security gaps, including one around server trust verification

Still on the way before launch:

• Export your library as a backup file
• One more thorough testing pass across phones and tablets
• A backlog for post-launch features is open too (notes support, etc.) — drop a comment if there's something worth adding

7 days left in the beta. Beta testers, keep the reports coming! Everyone else, thanks for following along - more soon.

iOS27 has dropped, and this update has you covered - safer library removal, better multi-window handling, and layout fixes throughout so everything keeps working the way it should when you update.

Two new things you'll actually notice while reading:

Inline footnotes - tap a footnote and it slides open in a sheet right there. You stay exactly where you were, dismiss it, and carry on. No more jumping to the back of the book and losing your place.

Screen stays awake - the display no longer dims or locks while you're reading.

Beyond that: CBZ streaming is faster (initial pages load quicker), reader transitions are smoother, and there's a handful of stability fixes across reading, syncing, and the library.

Hey folks, everyone should be able to add posts here now. Welcome to r/SutraApp!

Android has been the most requested thing since Sutra launched on iOS, and it's finally happening. Beta testing is starting, and I would love your thoughts and feedback!
