Worst Nav app ever!

I tried it out because of the good reviews. Maybe it works in Europe, but not in the USA. I see that they now have a N American version. From this experience they have a lot of work to do!
I used it for the first time, and it was the worst navigation app Ive ever used! It loses its place, cant recalculate if you deviate from the route it chose. Finally it just stopped responding. We then switched to Apple Maps, what a difference! It new instantly where we were and recalculated if we took a different route.
I want my money back! What a waste! I will give it a 1 star review in ITunes.
