The moment
The book rings a bell. You hesitate, you buy it, you already had it.
Back row, a box, the guest room. An hour of searching, or buying it again.
You can’t remember who has it. You don’t dare ask for it back.
How it works
No form between two books. Add first, shelve afterwards.
The camera stays open. Each barcode adds a book, the counter goes up, the pile grows.

Publisher, year, pages, category: Aldus cross-checks the BnF, Google Books and Open Library. When no source knows, the field stays empty. Never a made-up fact.

Open a shelf, tap “Shelve here” and scan what you put on it. Every book now has an address.

Features
Room, bookcase, shelf, box. Even in the back row. Shelves shows you your home, bookcase by bookcase.

Scan the book on the shop shelf: you have it, in this edition or another one, or not at all.

Who has it, since when, and a reminder if you want one. When it comes back, Aldus tells you where it goes.

Aldus tells them apart, and tells you before you buy a third.
Aldus knows the book’s category and suggests the shelf where you already keep the same kind.
Aldus follows your phone, by day and by night.

Backed up from the first book, back on a new phone, exportable as CSV at any time, with places and loans. No ads, no trackers.
