Hi Andrew,

I like it. My 2 cents:

1) Once i read your statement below I understand the app. I think you should make it plainly obvious that the app is for hiking (if that is your target market)

2) (This is based off the assumption that the target is hikers) The people who will use this are outdoors people. The app gui should be geared towards the market. I feel the app & web layout is geared for the high tech crew. Look at some legendary brands' color schemes (http://www.coleman.com/). Maybe partner up with a casing designer to provide rugged iphone cases (they'll be taking their iphone outdoors).

3) Why are you better than GPS motionx?

Cool app and I hope you can give me your feedback when our (phone halo) app releases.
