Shelfpad is a flat, 2D bookshelf you arrange by hand. It is not a reader for your comic files, it does not sync with a library server, and it is not a 3D room or a reading network. Your pictures and notes are never uploaded.
Shelfpad is a flat wall of shelves where you stand the books you own and arrange them by hand, by cover picture or a drawn spine with name and volume. Drag books into order or sort a shelf by series, hearts, artist or title, and switch between spines and covers.
No sign-up: shelves and pictures stay in this browser on this device. It is not a comic reader and syncs with no library server. Only with ISBN lookup turned on in Settings is the typed ISBN sent to Open Library; it starts off.
Example: add volumes 1 to 12 of a series at once, then keep a JSON backup with every picture.
