What's Your Favorite App, Jeff Corwin?

JC:  Google Earth, Hi Tide, and Nike Running. Google Earth, because I can find out where the heck I am this time. Besides, being able to send my wife a photo of my exact location, so that she can come and rescue me, is a bonus. Hi Tide, because we live on an island, and our lives are ruled by the tides. Really. Nike Running is pretty awesome too, since it tracks the pace and distance of my runs, and compares them to my earlier ones.
