Kamikura: PDF Bookshelf

Turn scattered PDFs into your personal bookshelf. Pick up reading right where you left off.

Kamikura is a PDF bookshelf app for iPhone and iPad. Instead of just storing and opening PDFs from Files or the cloud, Kamikura lets you arrange them on shelves, organize them for easy browsing, and treat them like a library you can actually enjoy reading from.

Books that are not yet on your device can be downloaded only when you need them. Save storage space while keeping the books you want ready to open anytime.

From manga and technical books to academic papers and reference materials, the more PDFs you collect, the more common the frustrations become: not knowing where a book is, seeing different shelf orders on different devices, or wanting books available only when you need them. Kamikura is designed to solve those problems through a better bookshelf experience.

Great for people who want to:

manage PDFs more like a real bookshelf use the same shelf order, reading progress, and bookmarks on both iPhone and iPad save device storage while keeping books easy to access read manga and documents comfortably in one app
