Customer Reviews

So bad it is dangerous! (1 star)
I just got finished trying to use this app on a backpacking trip and to say it is beyond terrible is an understatement. The maps are out of date and incomplete, the app crashes continuously with out a data connection, and it switches map modes for no reason and won't let you switch back. This is a bad app and should only be used when navigating a major city or to and from a mall, no one should ever take it into the woods with them ever! A

Don't waste your money... (1 star)
App constantly crashed. Interacting with the map (zoom and pan) was awful. Tracks were lost when the app crashed. I've never felt misled and like a refund was warranted, but this product did it for me. It's awful and should be pulled from the store.
