iOS Weather App

Doe any have any suggestions of a good weather app for the iOS? I have the iPhone 5 and iOS 6 so it should work with that. Would like the app to be free. If it is a paid app it needs to Weather Watcher Live or better. Thanks.

For general weather, I use WeatherBug or Weather Underground’s app. For rain alerts, I like Dark Sky. I also have RainAware, but don’t use it often.
