In reply to TheDrunkenBakers:
That's a proper 'D'oh!' moment. In my defence, my first seach for such an app brought up something authored by a chap called Leon Calcutt so I thought perhaps there wasn't such a thing, just third party apps using Met Office data.
The fact that the proper Met Office app isn't compatible with my tablet is a secondary issue, but it's now sitting happily on my phone.
Sheesh, what am I like, I'd be dangerous if I had a working brain, etc.
