Which weather app for my mobile phone?

[LookItsMeAgain]

I have downloaded Accuweather and there is the default Weather app that came with my iPhone but I'm wondering if I should pay for the full version of Accuweather or not.

What apps do you use to check the weather in your area and is it good/bad/indifferent? Do you pay for it and if you do, is it expensive per year or not?

I use my iPhone's default and think it's pretty accurate

WTF. What The Forecast?!!

It's a comedy app, with swearing, but it's weirdly the most accurate I've found.

I shop around until I find the most sunny optimistic forecast and stick with that.

Using the Met Office free app which I find to be accurate - having ditched the BBC weather app after they stopped using the Met Office for their weather data, and found their predictions to be very variable.
