Leveling up with KRDZ
The starting point
Pokémon, Magic, Yu-Gi-Oh!, One Piece and Lorcana collectors juggle several websites to identify and price their cards. KRDZ wanted to bring it all together in one app.
The challenge
Aggregate very different data and pricing sources behind a common model, while keeping holographic effects smooth and camera recognition reliable.
Challenge met
Collectors scan a card, see its value, add it to their collection and track the total value day by day, across 18 games.
