Weather app

There are many, many weather apps out there, but for something truly alternative in every sense of the word, try Carrot Weather (Android/iOS). Not only does it give you a wealth of useful weather information, it presents it all in a way that’s entertaining and engaging.
You get detailed forecasts for the coming days, together with a text commentary and visual guide, plus radar maps on iOS (in the pipeline for Android, apparently). Paying $5 a month for a subscription gives you a bunch of extras, including decades of meteorological history.
