After 6 rides the Motion X app on my iPhone (iPhone GPS) works very well providing the tracking information I want. The next problem to tackle was battery life. For $59 I purchased a Brunton Inspire power pack. It claims to be able to fully charge a smartphone 2 to 3 times. Brunton makes larger power packs as well if you like spending money. On my first ride with the iPhone/Brunton setup it kept my iPhone at 100% battery life while using the Motion X GPS for 2 1/2 hours of riding. A the end of the ride all four blue lights on the Brunton were still shining indicating between 75% and 100% battery life remaining on the Brunton.
