there is an app called ski tracks, don't know if you've heard of it. Basically what it does is it tracks how far you've rode, how much vertical ft. you have rode, your fastest speed and average speed, and how much runs you've done. It would be really cool if you could find a way to add all those features into your app, it would be like the ultimate snowboarders app.
Guys like me use a different GPS tracking app that applies to all sports I do. So I wouldn't want a snowboarding tracking app, then switch to a different one for another sport.
I guess it would make sense to have it all in one if snowboarding is the only thing you'd want to track...
