Ever wanted to know how much time you're hanging in the air with your snowboard?
AirTime can tell you, so you can tell others.
This application makes use of internal motion sensors of the iPhone and the iPod Touch. It detects and visualizes your snowboarding activities by applying tracking algorithms on the fly. A scrollable plot shows the past activities: flight duration and body motion.
Just start the application, put the iPhone/iPod Touch in your pocket, and go riding.
