Pokémon TCG Card Dex is a new app for Android and iOS from the the Pokémon Company, and it’s available for download right now. Its function is to help you catalogue your collection of Pokémon cards. The app allows you to scan any cards released since Sun & Moon, and then the app will instantly record that card in its records for you.
I’m looking at early Android reviews right now, and they’re quite positive, saying the interface is “very easy to use” and “straightforward.” If you’re a fan of Pokémon TCG, there’s not much reason not to grab this app. It’s a bummer that Pokémon TCG Card Dex can’t yet scan cards from all the earlier generations though. Maybe in a future update!
