Get it now! This app is great. I've used this a lot. It's great for knowing your heading if you are lost, but I like it for the altitude info. Granted GPS isn't 100% when it comes to altitude, it's better at LAT and LONG, but it's close enough. I used it while in an airplane at 30,000 feet going 500MPH, how did I know? This app told me. I used it while at Rainbow Curve on Trail Ridge Road in Rocky Mountain National Park in Colorado. 10,800ft above sea level. This made fact gathering fun!
