This is the most useful app I have ever used for navigation. Waypoints, distance, and record and auto follow work great! Then go back and see exactly where youve been and your speed throughout! Highly accurate charts and charts for all you needs. I have it both on my iPhone and iPad. Handheld GPS for those foggy days cant be beat anywhere for the price! Highly recommended!
