Arca TCG is a mobile app designed to help Pokémon Trading Card Game collectors catalog, organize, and track the value of their collections. Available for iPhone and Android, it identifies cards by camera scan, displaying details such as set, card number, and value without requiring manual searches. Collectors can add cards by variant, quantity, and grade, browse English and Japanese sets, monitor set completion, and track their progress through a digital Pokédex.

The app provides daily market prices from TCGplayer and Cardmarket in a preferred currency, along with price history charts covering periods from seven days to six months. Users can also view their collection’s estimated total value and follow changes over time. Arca is free to download and use, requires no account to get started, and offers a Pro upgrade with graded prices, full price history, and higher collection limits. Signing in enables collection backup and syncing across devices.
