6.3.0

PokéTrack is a real-time tracker for Pokemon GO, and it serves a single purpose, and that is to tell users when a rare Pokemon is nearby. Read more about PokéTrack  

One of the shticks of Pokemon GO is that users have to work very hard to find all the Pokemon that are out there, and the work gets so much more challenging when you have to catch one of the rare ones.
PokéTrack is one of the solutions that’s been developed by the community. Basically, players have access to the map and some pretty powerful scanning tools, which can help people identify the locations of Pokemon and Gyms.
The interesting part about this application is that it can also work in the background, so users will receive notifications about rare Pokemon even if they are not actively searching for them.
Of course, this is somewhat related to cheating, and it’s possible to get banned from using this app. Be warned!
