Currently, Pokedates is only available via your desktop, but if you're looking for a mobile Pokémon Go dating service, an app called Pokematch also launched this week on the Google Play store (the iOS version is on the way), according to a press release. Judging from the app's description, it sounds quite a bit like Tinder... but with Pokémon.
"The concept is simple, you are shown different people, who you then 'catch' by swiping right," the press release states. "Once you both catch each other, you will be matched in a chat conversion, where you can find a public Pokestop to meet up and start hunting Pokemon together."
You can always add your Pokémon Go to your Tinder profile bio and see what happens, too. Anyway, the fact that there are already at least two Pokémon Go-themed dating apps this soon after the game launched is probably a good indication that they'll be as plentiful as Pidgeys pretty soon.
