Not easy to use, not recommended
I bought this app for a recent trip to Missoula and Livingston and found it hard to use, so much so that I gave up. For reasons I don’t understand, it divides Montana into sectors which you have to select, then drill down, after which you are presented with dozens of icons and you have to click on each to know what they say. Maybe I just didn’t get it, but that’s a failure of usability design.
