iPhone Giveaway of the Day - Gravatron

This is the EARLY ACCESS version of Gravatron.

Gravatron records your adventure sports experience and gives you feedback in real time.

Record your airtime, jumps, speed, distance, elevation. No extra technology needed.
Your rides get saved to the Gravatron Webapp at http://app.gravatron.com

Continued use of GPS running in the background can dramatically decrease battery life.
