Replying to Making a Powder finding app

I'm thinking about developing a mobile(iOS) Ski/Snowboard social network called PowHunter. The basic idea is that it displays information about resorts, snow conditions, and other basic weather features, but then it starts to get more social. Users would be able to post pictures or status about mountain conditions or create "Powder Patches", places where snow is good, like off-piste runs, or backcountry areas. Powder Patches would have a lot of data associated with them from when you make them like snow conditions, rocks, traffic, and using that data we could start to analyze those areas. When you arrive at a resort the current best area would be displayed to you at the top of the feed and it would update as areas start to get skied out. Because I know that sometimes you want areas to be a secret, Powder Patches can be saved to your account only, and would also be taken into account, or shared with friends who are other users. PowHunter would also have other basic features like lift status, run traffic, lodge traffic and more, and it if we continue development, it should be available by at latest the end of this upcoming season. It should sell for either $0.99 or $1.99 because I don't really want to add ads. Let me know what you think or if you think of any other features that you think would be cool to be added.
