FanWiki. BookTracker. Library
Free · Designed for iPad. Not verified for macOS.
Finally a spoiler-free, chapter-by-chapter Fan-Wiki! Reading sessions with music, a library to organize your books, a calendar, and a reading goal to chase down your TBR.
That moment when a quick online search about a character spoils the whole plot of your book. That pain is why we built BookBubble. A fan-powered and spoiler-free Wiki that only unlocks, what you’ve actually read so far.
