Has anyone downloaded the Hover App? It had way better reviews than b4ufly app but I had a question, I know the red is no fly zones because of airports or stadiums or natl parks,but what is the blue shaded images for?

Might be TFR areas but they do not appear to be up to date according to B4ufky info

I really like the hover app, but I don't use it to replace B4UFly.  Mostly, I use it to check for winds and weather.  There are areas that I KNOW are "action required" that Hover doesn't pick up on.  It's more of a companion for B4
