Tsundoku Tower

Tsundoku Tower turns unread books into a physical-looking 3D tower. Add titles, authors, ISBN numbers, page counts, formats, and notes. The app estimates tower height, unread pages, finished books, recent progress, and how many years it may take to finish your unread pile at your reading pace. ISBN scanning is local barcode reading only. There are no ads, analytics, external book APIs, or developer servers.
