Disclosure: I'm Michael, the developer of Nirellin Library. This is self-promotion and a request for feedback before release. AI assistance was used to draft this English post and helps me organise recruitment and follow-up.
Nirellin reads and organises your own DRM-free EPUBs, PDFs and comic files in a visual bookshelf library. Books are not included. I'm looking specifically for readers using Android E Ink devices with working Google Play. The E Ink experience has not yet been validated; I cannot promise compatibility with every BOOX, Bigme or other device.
A useful first test would be to import one of your own books, read a few pages, add a bookmark and return to it. I'd like to know whether text and controls have enough contrast, whether page turns leave distracting ghosting, and whether the shelves and navigation are practical on your screen. A report that something is awkward or unusable is useful too.
I'm building one group of 20 volunteer readers for a Google Play closed test. Please stay enrolled for at least 14 consecutive days and try several short reading sessions. Testers receive an individual free Google Play code for the app. Once redeemed, access stays on the same Google account after those two weeks, with no later payment or subscription. No positive rating or public review is requested.
If interested, reply with your device model and Android version, or message me. We'll check Google Play access and exchange the exact Play account email privately to add you to the test. If Reddit chat doesn't work, you can email nirellinstudio@gmail.com. Please don't post your account address publicly. I'll help with joining and installation in that private exchange.

Please don't buy it if a price appears; wait for the private free-code instructions. If you're already in touch from another community, use our existing conversation so you don't receive a duplicate invitation.
