PokeTrack for Pokemon GO is an app that allows you to place and track your Pokemon, Gym, and PokeStop hotspots on a map for quickly retrieving them with a single tap.
The information is kept private so no one can see your secret locations for finding the most rare Pokemon! Build your own private location map without worrying about other people marking false Pokemon locations.
The app also has a Guide & Tips section that explains many of the discovered rules and tips in Pokemon GO.
