Works sometimes
Ive used this app for over a year now. It works most of the time, but its buggy, crashes often, and its far too easy to erase an entire trip without it being saved permanently. Also the newest version (as of oct 12 2014) for ios 8 crashes constantly when viewing your routes. By the time you scroll down to see the route on the map, it freezes. I highly suggest you get the "myTracks" app instead.
