DeckBox is an unofficial, fan-made deck-building app for creating and managing your Pokémon TCG decks. It supports all the major expansions and sets, so you can build and experiment with any deck. You can import and export decklists in a format that is compatible with most games, so you don't need to create an account or log in. The app allows you to edit your decks on your own device and also export them to your online game.

This is an important update as we have made the app open source. Now, anyone can modify the app, build their own decks, and share them with the community. We have added the option to add your own images as cards and we have made some other updates and changes to the app.

We hope that you will enjoy using this app and that you will find it helpful. If you have any questions or comments about it, please let us know.
