Foilio is an independent, unofficial app and online hub for trading card collectors and sellers. It helps users scan cards to identify them, check reference values, organize collections, and follow market activity. The platform covers Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Lorcana, and other card games, with tools including a card scanner, market index, price comparisons, trade checker, deck-cost guides, and more.

Foilio also lets users create a free shop with a personal link to list cards and collectibles. Sellers can upload cards without a stated limit and share their shop wherever they already connect with buyers. Interested buyers message the seller and pay them directly; Foilio says it charges no fees or commission and does not handle the money. Users can browse shop listings or search for cards in stock.

Foilio’s prices are independent reference estimates drawn from attributed card catalogs and sources such as Cardmarket data, Scryfall, and YGOPRODeck. They are not sale records, appraisals, or financial advice.
