First Tracks
Alarms are great if you're looking to be among the first to hit the slopes in the morning — but there's something disappointing about waking with the sun only to find out that last night's fresh snow has already been befouled. Keep that from happening with First Tracks. This app from cold weather outfitter Helly Hansen uses your location and local weather information to wake you up at your designated time if nothing's changed, but earlier than expected if there's fresh powder to be had. It's as close as you can come to having a snow sensor in your pocket.
