Im a NY-based skier and downloaded this app for my vacation. Its almost identical to the app I have for Hunter Mountain. The snow reports are good, and the tracking feature works well. I could do without the blue status bar indicating that the app is using my location; I already know that and it interferes with the display of my phone. The battery drainage didnt seem to be as significant to me as others indicated, but I have a backup pack. Finally, I wish it would stop asking me to turn on "beacon", whatever that is. Overall, its decent but needs some refinement to the UI and notifications.
