This app works great until it crashes. Out of the first four attempts to record a track, three quit unexpectedly, losing all of my track up until the point of the crash. I havent yet determined what causes the app to simply quit. The interface and options are great though. :) Hopefully this app will get fixed because I really like it when it works. v2.2 - Ouch! Now it doesnt work right at all. Track points skip all over the world. Then attempting to save the bogus track crashed the app. iPhone 4s
