bookiboo

Manage your library. Never buy a book twice. Know which books you own but have not read yet.

With bookiboo you can look at your library at one place. It does not matter if you own the book physically or have it in any of the big book apps out there. You can create groups like 'Favorite Books'. A book can have different read states: In Wishlist, Not read, In progress, Read. You can filter books and search them really quick.
