Nocturne: Card Value Scanner

iPhone app by Kamal Nasir

Nocturne is a card value scanner for iPhone that identifies Pokémon, Magic and One Piece cards, grades their condition and shows what they are worth.

What it does

• Point the camera at a Pokémon, Magic: The Gathering or One Piece card and it is identified on the iPhone, offline, or import a photo of the card instead
• Digital condition grading from your photos, with centering, corners, edges and surface sub-scores and a defect map showing where the wear is
• Market prices for English printings based on TCGplayer and Cardmarket data, with a link from every card to eBay sold listings for current numbers
• Every English One Piece Card Game set, with alternate arts and reprints priced as their own printings, told apart by the printed card number
• Teach Mode learns a rare promo, a misprint or an unknown card from a single photo, and you can add fully custom cards to your catalog
• Collections with quantities, set completion, and an offline catalog of over 165,000 cards across more than 1,600 sets
• Portfolio tools: cost basis, profit and loss, recorded sales, a shareable poster of your collection and CSV export, with no account and no ads

Questions people ask

How do I find out what my Pokémon cards are worth?

Identify the exact card and printing, then look at recent sold prices for it. A scanner app such as Nocturne identifies the card from a photo and shows a market price based on TCGplayer and Cardmarket data, with a link to eBay sold listings for current numbers.

Can an app grade a trading card's condition?

An app can estimate condition from photos. Nocturne scores centering, corners, edges and surface and marks where the wear is, but the grade is a guide for buying and selling, not a substitute for official grading services.

Is there an app that scans One Piece cards?

Yes. Nocturne scans One Piece Card Game cards along with Pokémon and Magic: The Gathering, covers every English One Piece set, and reads the printed card number to tell an alternate art from its base card.
