Just as the name suggests, the service works by matching singles for -- you guessed it -- playing Pokémon Go together on dates in their cities. Here's how the company describes it, per the release:
"'PokeDates' are curated dates where singles are matched based on their questionnaire preferences and a mutual desire to play Pokemon Go. PokeDates coordinates all the details, from selecting the match to finding a time based on members' provided availability, to selecting a convenient PokeGym or PokeStop meeting point."
However, just like advancing to high levels in the game, you're going to have to pay up to advance to a second "PokeDate" and beyond, each of which costs $20 after the free introductory "PokeDate" (because people need to cash in on the Pokémon insanity). To sign up for the service, you have to answer a few questions and share when you're free for said dates. With any luck, and perhaps a few Great Balls, you'll match up with another trainer, confirm a "PokeDate," and set off into the Rattata-infested wild of your neighborhood together.
