Hey CGH,
Thanks for your comments. I've thought about each of these issues:
1 & 2) We want to market the app to anyone who wants to take a track. It being for hikers is a nice bonus, but in our experience, the market isn't big enough. We have a fairly successful app called TrailBehind just for hikers, but we hope people use this for cars, road-biking, etc.
Note that we did have art for this app that was for hikers - just like www.trailbehind.com - but we changed it for a broader appeal.
3. We are better than Motion X for the following reasons:
- we have MyTopo maps
- we have far more complete waypoint search
- I would argue our GUI is simpler
- on things like track accuracy and batter consumption, we are equal if not better
