The webapp
This is a brand new web app that allows you to set your location and find the Pokemon near you! It uses Niantic API's so it's quit accurate.
So go hunt these pokemons:
Confirmation
Rumors say that it only works in USA, but I tried it in Oslo, Norway!
I can verify that it works! I opened up the app, looked at the nearby grid, then there was a Cubone nearby.
I ran over to the Cubone location based on the pokevision location, and POW, the Cubone popped up in my Pokemon map. I caught it!

I am not the creator of this webapp, but I thought that this community should see this awesome new app!
