Right now, the Web—not apps—appear to be the best way to find rare Pokémon in Pokémon Go.
Gotta Catch Em All is probably the best Pokemon Go map out there, though it's restricted to Boston for the moment.
If you ve been wondering how to find Pikachu, Scyther, Electabuzz, or any other rare Pokémon, you might not have to wait much longer: new crowdsourced Pokémon Go maps are teaching players how to find Pokémon in Pokémon Go.
At least four Pokémon Go maps are available: the first, at Pokecrew.com, zeroes in on your location and begins showing what Pokémon might be nearby.
Each player can capture a Pokémon using a Pokéball, then train it at a local gym.
Special items, such as incense and lures, are used to attract new Pokémon to the player.
