Logbook: OPTCG Card Scanner

Photograph a card. Logbook tells you which printing you pulled, base, parallel, alt art or manga rare, and what it is worth this morning at Cardmarket prices.

"Which printing" is the part most collection apps get wrong. A single card number can exist as four or five different prints, and the gap between them is often a hundred euros. Logbook shows you every printing that shares the number and lets you pick the one in your hand, so your collection is right at the level where the value actually sits.

HOW THE SCAN WORKS One photo. The recogniser runs entirely on your iPhone using Apple's Vision framework, so no picture is uploaded, no server ever sees your cards, and it works with no signal. It reads the code printed in the corner of the card, which means Japanese, English and French prints all resolve to the same entry. If a card is too worn or too glossy to read, type the code in yourself.

WHAT IS IN IT

• 2,900 cards and 5,300 printings, from OP01 through the current set, plus 498 sealed products
• Cardmarket's price guide, in euros, refreshed every morning
• Set completion for every set, counted printing by printing
• A wishlist pinned to the exact printing you want, which clears itself the moment you scan that card
• Sealed boxes, decks and cases in the same portfolio as your singles, with the price you paid and what they are worth now
• Multiple copies per card, and a running total for everything you own

ABOUT THE PRICES They come from Cardmarket, the European marketplace, and they are shown in euros. They are a market indication, not an offer and not financial advice. What a card really sells for depends on its condition, its grading and its language. Where a printing cannot be matched to a Cardmarket product, the figure is marked as approximate rather than invented.

WHAT IT COSTS Everything in Logbook is free up to 10 items. Not a trimmed version: the prices, the printings, the sets, the wishlist and the sealed products are all there. Past 10 items Logbook is a subscription, and what the subscription buys is the removal of that ceiling. There is nothing else behind it. Identifying a card is part of the app, so past 10 items you subscribe to keep scanning.

Weekly, monthly and yearly plans. No free trial. Cancel any time from your Apple ID settings. If you stop, anything past your first 10 items is hidden until you resume.

WHO IT IS FOR Collectors and investors, not deck builders. There is no deck editor, no meta report, no tier list and no tournament tooling. Logbook does one job: it knows what you own, down to the printing, and what it is worth this morning.

A free account is required, so that your collection survives a lost phone and follows you to the next one.
