iPhone
Browse your OPDS library, download EPUB books, and send them directly to Kindle in seconds. The easiest way to access your self-hosted ebook collection.
Your self-hosted library is packed with thousands of worlds, but getting them onto your Kindle shouldn’t feel like fighting ancient technology. If you are tired of messy email setups, clunky USB cables, and formatting errors that ruin your reading immersion, you aren't alone.
BookBridge is the ultimate, elegant command center built for book lovers, self-hosters, and power readers. Whether you manage a sprawling private server (Calibre, Kavita, Ubooquity) via OPDS or just have loose files scattered across your phone, BookBridge turns your digital chaos into a flawless, premium reading experience. In exactly one tap, BookBridge converts, optimizes, and beams any book from your personal collection directly to your e-reader.
But BookBridge does something far deeper than just move files, it transforms how you curate your reading life. Finding your next great read shouldn’t depend on generic, mainstream algorithms. BookBridge deconstructs books down to their genetic code, extracting core story elements, pacing, prose styles, and micro-tropes so you can accurately hunt down books that perfectly match your specific mood.
It’s a complete, beautiful digital bookshelf right on your iPhone.
