Bibliomemo — Android PDF/EPUB reader that turns highlights into flashcards

[check2boxes]

Hi everyone,

We're a small independent team from Austria, and we've built an Android reader called Bibliomemo. The idea came from a simple frustration: we highlighted a lot while reading, and forgot almost all of it a few weeks later.

What it does:
- Reads PDF and EPUB (TOC, bookmarks, night mode; font, size and spacing for EPUB)
- Highlights in four colours and notes on any passage, chapter or book; all notes in one place, exportable as Markdown
- Turns any passage into a flashcard (Q&A or fill in the blank), reviewed with spaced repetition (FSRS)
- Reads PDF and EPUB aloud with natural offline voices, word by word (EN, DE, ES, IT, FR)

Privacy: no account, no server, no ads, no tracking. Books and notes stay on the phone; backup goes to a file you keep.

Limitations, honestly:
- Android only for now
- No DjVu, MOBI or comics; no Calibre or OPDS sync
- Five books are free; unlimited books are a one-time purchase (no subscription)

We'd really value honest feedback from people who read a lot — what's missing, what's annoying, what would make you switch. Happy to answer any questions here.
