Great app works well
Works very well against my digital system in my auto. A friend has about the same system on his new iPhone 6 Plus S. This app works about the same. I will be using it on my bike weekly trips, when we bike between 35 and 50 miles a day. So this app states the speed and distance. The best in my app selection.
