Quite helpful!

This app is super helpful because you can scope out portals that are out of range of your scanner. It also helps with planning larger links and fields!

This is a definite must have for people playing the game on a large scale BD

Cons:
The interface is a little cumbersome to use, but you get used to it.

The portals are a little laggy to load.

Expensive for the full app.
