Can anyone recommend a good weather app for iPhone? I find the Yahoo one installed to be a bit lacking with a lot of inaccurate info. at times.
Welcome to the forum Simon. In a word...Accuweather. Very nice layout, very accurate, and lots of detail if you want to drill down a bit deeper. It's not free but it's one of the few apps I check daily and feel the 4 bucks is well justified.
There is also Weather Line? It gets a bit beyond current temperature and seems to do a godd job of forecasting. (Data comes from forecast.io)
Basically...its Dark Sky + machine learning = pretty looking weather interface. There are minute-by-minute updates and an army of widgets that make it pretty easy to check weather at a glance for locations around the world. It's very visual.
