Sounds like a neat idea, but there are already things out there comparable to this. Personally, I'll stick to my DHC site for good 'ol talk (doesn't take any longer getting here from my bookmarks than an app does) and I use Mossy Oak Hunting Weather App. This app does everything your last point says and then some.
Good luck, nonetheless
