A. CARROT is, without a doubt, the best weather app out there. With a clean interface, a funny weather assistant with witty commentary and a freemium option, Carrot is one fun weather app to try out. AccuWeather is another excellent all-rounder app with accurate data presented using a clean, minimalist UI. If you'd want the data from the source, Met Office is the best free app for Android and iOS. Among the paid apps, there are several apps like the Weather Channel for Android & iOS, both (premium) and Dark Sky for iPhone.
