The blurb below from their website…

Always see where your friends are on the slopes
Because it is often hard to find your friends on the slopes when you decide to split up.

Phone calls and text messages are easily missed and when you get a response 45 minutes later, the question where they were is no longer relevant.

Wouldn’t it be great if you could see where your friends are on the slopes?

With Snowciety you can do just that!

See your route and all the important stats of your day on the slopes
So how do we do that?

When you open Snowciety in the morning and start a recording, we begin to track your location, speed, distance, etc and share that with your friends in real-time.

We also store all that information, so you have an overview of your days on the slopes. But not only your runs, but also those of your friends!

Share your skiing with your friends on Snowciety or with the world on Facebook and Twitter
We automatically share your tracks with your friends on Snowciety. You can like and comment on them and compare your stats with your friends.

You can also choose to share your tracks on Facebook and Twitter, to share them with the rest of the world.

There is no better way to track your skiing!
