People around the world are trying to catch all Nintendo animals in Pokemon Go game. This may look crazy, but it is very addictive game. Currently the Pokemon tracking feature does not work, so this task is difficult. However, there are several websites which may help you to catch them all. As far, the Niantic API is not encrypted, so you can slightly bend the rules of the game.
PokeVision
In my opinion, this is one of the best Pokemon Go locator service. You can select any location and it will show you all Nintendo animals in this area. The best feature is that PokeVision shows also appearance time.
PokeCrew
This service does not get the real-data from Niantic service. PokeCrew will show you where and when Pokemons are spewing in your area. Generally, it is very helpful if you want to catch the specific Pokemon. PokeCrew will tell you where you should look for.
Pokemapper
This website has very nice looking design. This does not display Pokemon icons which are very unreadable on the map. Pokemapper uses colorized dots which reflect Pokemon type. For an example, blue dots represent water Pokemons etc.
PoketScan
This application was designed by developers from Cloud Technologies. This is not official product of this company, but it is an additional project of its employees. PoketScan uses the API to Naintic servers and is able to show the exact location of wild Pokemon in your area. Of course, a lot of Pokemon Go players use this website, so it sometimes doe not work because of huge load.
PokeFind
This website will help you to catch the selected Pokemon. It has also very useful evolve calculator which may help you to select the best Pokemon to evolve. It shows also locations of PokeStops and Gyms. PokeFind show also Lures in the real-time.
New York City Pokemap
This is customized Google map for New York residents. It does not show the location of Nintendo animals, but it is focused on PokeStops and Gyms. Therefore, it should be very useful if you do not know where you can get a lot of Poke Balls or join Lure party.
