At BookFusion, we are passionate about providing the very best reading experience regardless of content type or formats. Our mission is to revolutionize the way we read and interact with eBooks, audiobooks and articles by building a platform that allows readers to obtain, organize, read, share and derive value from content regardless of whether they are reading to learn, for work or for pleasure. 

After over 400 years ago since the Gutenberg printing press, reading has still remained just a flat representation of print even in the digital age. We are building a platform that provides the reading experience of the future but delivered today by adding interactivity, integrating natural language processing & machine learning and cutting edge technologies.

  • Seamlessly sync data between the iOS app and backend services while keeping the UI smooth and responsive.
