The past couple of months I have been working on an app called Snowcast. It will use HTML5 Geo to grab a users location and return resorts nearby. The UI is extremely simple and clean. That was the goal from day one. Yes, there are other snow conditions apps out there, but the sites are way to complicated and this focus on:
What is the information you want and need to see before you head out in the AM to the mountains?
I am using large icons to showcase the pieces of information, so you can relate to which icon corresponds with what piece of data (New snow, open trails, open lifts). I will be posting some quick shots of it later this week. You can check out the landing page at www.snowcastapp.com
I am also looking in to Backbone.js to rebuild the app upon instead of JS files and a HTML file. I feel it will allow for easier scalability.
