I had not seen this free Weather app before. It’s not bad, it is free and shows a banner ad along the bottom (also no retina graphics). The reason I am linking to it though, is because I think it makes decent use of the space provided by the iPad. It’s not the best use, but it doesn’t feel like the app is trying to cram information in because there is room to cram information in.
That said the banner ad is a deal breaker — not to mention the app is pretty sluggish.
(Be sure to pinch on the forecast data to move between views — nice touch.)
Again I don’t think this is a great app, but I do think it is one of the better ones — especially for a free app.
