There have been quite a few third party websites/apps that have been created to allow you to locate specific Pokemon in Pokemon Go at a faster rate.
The new website in question is called PokeVision and you can check it out by clicking here. It is supposed to tell you where specific Pokemon will be in Pokemon Go in real time. It’s helpful to use if you are sick of seeing the same Pokemon.
Here’s a description of Pokevision’s tool: “Pokevision is a Pokemon tracker/locator for the mobile game Pokemon Go. It uses the Niantic API to grab the location of all Pokemon near your (or your selected location) and display them on the map in real-time; this means if it is displayed on the map, you can go out and catch them! Note: Rarer pokemons have a shorter appearance time so they might despawn; make sure to be quick and keep an eye on their timers!”
There are downsides to this website and that’s because it’s reliant on Pokemon Go’s own servers. Not to mention the accuracy of the website is affected because of this. However, people that have used it so far feel that it has been helpful when the servers are working. Just search for the area you live in by using the search bar at the top.
