Dex is a digital collection-management platform for Pokémon Trading Card Game collectors, available on iOS, Android, and the web. Trusted by collectors since 2021, it helps users organize their cards, monitor collection value, and discover what they still need. Its scanning tool identifies cards and variants from a camera image, and can add a whole stack directly to a collection or folder, reducing manual entry.

Dex covers Pokémon TCG expansions across international, Japanese, and Simplified Chinese releases. Collectors can track individual printings—including first editions, shadowless cards, jumbo cards, and stamped promos—alongside market prices from TCGplayer, Cardmarket, CardTrader, and eBay, converted to their currency. Collection insights summarize card counts, estimated value, rarity breakdowns, and notable cards. Users can also create folders, wishlists, trade lists, decks, and custom collecting goals, fill out a Pokédex-style view of Pokémon cards, and connect with friends to compare collections and identify potential trades. With search, reviews, pricing information, news, and help resources, Dex brings practical tools for building and managing a Pokémon card collection together in one service.
