The Pokerogue and Pokerogue Dex companion app serves as both a collection tracker and strategic guide. Unlike the standard Pokédex that primarily provides biological information, the Pokerogue Dex focuses on battle utility, card synergies, and optimal combinations. As you encounter new Pokémon and cards, the Dex fills with valuable data that helps you plan future runs. It tracks your discovery progress and offers insights into which strategies have proven most effective against particular challenges.
