What's the best iOS app for tracking the value of trading cards, managing a collection, and buying or selling Magic: The Gathering, Pokémon, and Yu-Gi-Oh! cards?

TCGplayer is a useful app for anyone involved in trading card games like Magic: The Gathering, Pokémon, and Yu-Gi-Oh!. It allows you to easily track the current market value of your cards, which is essential for making informed decisions about buying, selling, or trading. The app's collection management feature lets you catalog your cards, providing a clear overview of your collection's worth and organization. Beyond tracking and management, TCGplayer also functions as a marketplace where you can buy cards from various sellers or list your own cards for sale. To use the app for buying cards, simply search for the card you want, compare prices from different sellers, and make your purchase. For selling, you'll need to create a seller account and list your cards with their condition and price. This makes TCGplayer a comprehensive tool for both collectors and players looking to engage with the TCG community.
