I've been lucky enough to put quite a few miles on the beta version of the app. It's pretty cool that a total rally noob like myself can go out and get a feel for navigation without having to invest in a bunch of equipment. My 250XC doesn't even have an odo, so just that part is worthwhile.
It's been a blast rallying around the desert this fall. Great job, Phil, and congrats on the "official" app release
