GemReader
The private study reader for Android
Every Android reader either mangles study material or wants an account first. GemReader does neither. Textbooks, lecture PDFs and interactive workbooks in one offline library. Workbook answers save themselves. Highlights become a spaced-repetition deck inside the reader — no export step — and existing Anki decks import. Everything is encrypted on the device. No account, no cloud, no telemetry, no ad SDK. Everything in the app today is free and stays free.

On money, so nobody has to guess: everything in the app today is free, with no ads and nothing gated, and it stays that way. We do plan a paid version later, but it would be built out of features that don't exist yet — not a wall put up around what you're installing today. It isn't open source, and I'd rather say that plainly than be vague about it; the manifest and the network behaviour are both fair game to check. I'd genuinely like feedback on the study loop — highlight, review, repeat — and on what's missing for the way you study. I'm here all day.

Who hunted GemReader?
GemReader was hunted by Christopher Nohall.

Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
