Collector's Logbook

Collector's Logbook — what you have of a series, what's missing and what you have twice.

For everyone collecting manga volumes, stickers, trading cards, records or figures who wants to know in three seconds at the shop: do I already have volume 87?

WHAT YOU CAN DO
• Create collections with series inside – numbered (“Manga series, volumes 1 to 112”) or by name (“Albums”)
• Tile grid per series: one tap switches missing → have → duplicate
• Keep duplicates as a count – with three copies you can swap two
• Read your progress: “97 of 112 · Missing: 15 · Duplicates: 3”
• “Missing” filter as your shopping list; extend a series with one button when a new volume appears
• Share a swap list as text – via Discord, Signal or e-mail, without giving out your phone number: “Wanted: 3, 7, 45-48 / Have duplicates: 12, 19”
• Photo per item: for photocards and trading cards the series shows a picture grid
• Your own background image from the gallery
• Search across everything: “87” looks it up in every series whose range contains the number
• Per item, optionally: condition 1–5, purchase date, purchase price, storage location, note
• CSV backup via Android share – and back in, without duplicates
• Everything offline and local on your device

NOTE
The app contains no catalogue and fetches no titles, covers or prices. You set up your own series – so nothing goes stale and your data never leaves the device. The app does not estimate value; it counts what is missing. The app is a tool and does not replace professional advice; check results before you rely on them.
