Seriously love this app!! Very accurate and reliable. Track log showing elevation, distance, and time/date stamps is really nice. You can easily email/share track logs....just tried it today. Great for tracking distance traveled and for visually seeing your track on the map. I also use it to capture/create waypoints and view current location on the map...flawless. This app pretty much does what my $500 Garmin does...in terms of what I primarily use it for. I use his Mac GPSPro software on Mac OSX and absolutely love it! And this guy is as good as it gets when it comes to responsiveness and support... I cannot emphasize this enough...see for yourself. No affiliation....just a very satisfied outdoor enthusiast!
