Cardfight Vanguard Database is a free app for Android devices that allows players to access details of all the officially released English cards, plus English versions of many Japanese cards that have not been released in English. The app can be used to build lists and create custom decks, just like in the game.

There is a search function that works like the built-in card search function, and you can also search through all the sets that have been released in the game. There is an English set name, release date, and list price function that will allow you to get all the English cards from a certain set, and you can also get all the sets in a certain period, such as the current set.
