YieldStack's answer

DarkDex.app's answer:
DarkDex began as a personal tool. A Pokémon collector wanted to know what his collection was really worth and got tired of English-only, near-mint-only prices and checking values by hand. It grew into a full web app and is now open to everyone, still shaped by feedback from the collector community.
