Vail Resorts Inc.'s EpicMix application changed the industry in 2010 by using radio-frequency ID tags in lift tickets and passes to communicate with scanners on lifts to tally riders' vertical feet and runs. 

Now the company Active Network has developed a smartphone app to count a skier or snowboarder's jumps, spins and other hill stats, like average hang time. 

It works with the help of a motion sensor made by Golden, Colo.-based Mosoro that is based on Bluetooth LE technology. 

The app will likely come out early next year. The app will probably be free, while the sensor is around $100.
