Unfortunately I cannot test such innovate Android applications like SatSki daily. But I am sure, that many of my ski and snowboard enthusiastic readers will love this program, too!
What is it?
To get started, select your desired ski resort. Choose from over 100 ski resorts (18x Canada, 42x USA). Including Vail, Banff, Stowe, Mont Tremblant and Aspen... The complete list is linked at "other". 
Afterwards your have access to extensive statistic functions. This includes information about speeds and distances that can be replayed on your PC (Google Earth), when you're back home. 
In addition, SatSki can give you detailed information on restaurants, bars, doctors, ski rental shops and schools - even in offline use. If your data plan works (abroad), you can also use "live services". This shows, for example where your friends (who also use SatSki) are on the map and provides current information from your resort. 
Perhaps the most interesting function is navigation: did you ever try to find the best route to some Ski Hut? This app will help you out by suggesting a configurable (red / black runs) route (see screenshots). Should you ever be in the unfortunate position of an emergency, SatSki can show the local emergency phone number next to your GPS coordinates. 
Finally, the only drawback: licensing seems too complicated. There are 3 "versions":

• Bronze: 1 Resort for 2 weeks (7.90 USD)
• Silver: 1 Resort for 12 months (13.00 USD)
• Gold: Unlimited Resorts for 12 months (15.50 USD)

But what are 16 bucks (for a year) in comparison with your ski pass? Everyone interested in winter sports,should really download the free "SatSki Lite" version from Android Market and play bit with the demo resort.
