Poor App with Poor Support

They offer a premium version which I have tried twice now to purchase. First they offer a price in the wrong currency, and by the time they respond to my inquiry the sale is over and they wont honour the advertised price even though they apologize for their mistake.

So I wait for the next "sale" of "premium". I try to buy it and they say to select "offline maps" in order to take advantage of their special price. Absolutely nothing shows up in order to upgrade to "premium". So, I write them about about this and no one responds. And when they do, no doubt the "sale" will be over.

Based on my experience so far this whole "premium" thing is equivalent to a scam.
