Very good.

Always use it while hiking or just wandering in a city that I dont know much.

2016 Updates
No longer works on my iphone6 with IOS 8.1.2. Contacted support. Was told the only solution was for me to upgrade to the latest ios version which i am very reluctant to do. It is a shame that i thought it was one of the greatest app i purchased. Now they are not even bother to fix the compatibility issue.
So, if you are on an old ios, do not update the app.
