A reliable reader and library manager that keeps DRM?-free books, classifications, downloads, and reading progress consistent across phones, tablets, and computers.

Medium opportunity (73%)
Readers with large personal libraries cannot reliably control which files appear, distinguish books from comics and documents, or keep books and reading positions synchronized across devices. Freezing, disappearing downloads, unwanted folder scanning, and broken progress records force users to reorganize files, search for their last page, or repeatedly download books. The evidence supports an independent workflow for DRM?-free personal libraries, although it does not establish access to protected Kindle purchases.
Build a local-first ebook library that imports DRM?-free EPUB?, PDF?, and comic files from explicitly selected folders, preserves user-defined categories, and synchronizes files and reading state across devices. Start with an Android reader and a desktop companion that provide deterministic folder inclusion rules, offline storage, exportable metadata, and conflict-safe progress synchronization. Do not promise migration of protected Kindle purchases; support user-owned files and authorized exports.
Readers increasingly use several devices while incumbent reading applications bind library management and synchronization to closed ecosystems. Repeated complaints about basic reliability create an opening for a narrowly scoped, portable library product whose data can be inspected, backed up, and exported.

I used the free version for about 6 months before I purchased the premium version. The free version did everything I needed it to, and more. The paid features are nice to have, but really the core functionality is not missing at all in the free version (no ads!) The books are editable by name, author's name, series name and book number in that series, file name, and the description. It also has tags (collections), favorites, read status and lots of setti
Everything an app should be. Small, full featured, no ads. And no problems so far. I can sync devices through Drive, etc. But I'll probably go premium just to support development
this is a good app but , yall should incorporate an option to create an account and sync books across devices. I don't want to have to download 200+ files on a different device everytime I don't have access to my phone. it doesn't help that the backup does not restore files just titles (not even covers smh)
Go beyond the grade and inspect the evidence behind this opportunity.
