John,
In order to use these apps, I assume you can't put your phone in airplane mode, correct?
I've found that my iPhone is pretty much useless for tracking, since he batteries run out so fast if it isn't in airplane mode. I miss my android phone. It actually tracked well and had decent battery life. I used to put it in airplane mode, then turn on the GPS.
Please let us know your experience with it. Since we're somewhat local to each other, I would love to check it out in person sometime, if we happen to be interested in doing the same hike at some point. I'm also very interested in your UL gear.
