Press the menu key on all the pages. It has cool functions.
DropDB - Delete all stats.
Toggle GPS - Turn on Tracking.
(Inside altitude graph)
Confirm Horizontal line - Choose a line that passes through all your runs.
Delete to the right - Cut off data to the right of selected point, for getting rid of stats after you've gotten into the car, etc.
Turn on this app, leave it in your pocket, and it'll track your snowboarding or skiing stats throughout the day. No more fumbling with your phone at the start and end of each run!
