If you’re having a tough time finding certain pokémon in Pokémon Go, PokéVision uses the Niantic API to show you their actual locations, and how long they’ll be there.
There are a lot of Pokémon Go maps out there, but most of them, like the popular app Poke Radar, rely on the Pokémon Go community to post pokémon locations. Because PokéVision uses the Niantic API, however, it can show you exactly where every pokémon is at the present moment, and for how long it’s going to be there before it disappears. I thought it sounded too good to be true, so I tried it out this morning. Sure enough, I was able to catch a Dratini in my area that had been evading me since launch. The downsides are you can’t filter by pokémon type (yet), and there’s no app available for iOS or Android. You can only run it in a browser (but mobile browser seems to work fine). It’s hard to imagine Niantic wanting a service like this to exist, though, so who knows how long it will last. And personally, relying on a tool like this takes a lot of the fun out of Pokémon Go, so use at your own risk. If you want to check it out for yourself, head to the link below.
