Choppy in iOS 9
Have loved this app, but it is almost unusable for me in iOS 9. The location stops updating, and this effects all mapping apps. I was routing in Maps the other day with FoW running in the background and my position icon kept jumping around, causing it to recalculate my route every block or so. Once I quit FoW Maps started working properly again.
