We received an interesting email from Ripxx this morning, stating that due to an unprecedented outpouring of comments on our previous post for its sports GPS, the company's gone and developed its very own iPhone app. That's right, instead of planning your ski trips around a piece of dedicated hardware, you can now do it on the same device you use to read Texts From Last Night while sitting on the loo. The Ripxx iPhone Ski App, as it's called, features trail maps from over 200 North American ski resorts, Google Maps integration, the ability to track time, speed, distance, and vertical drop for your various trips down the mountain. Whatever that means. But hey -- it's only five bucks! And it's available now. Video after the break.
