Not at all worthwhile.

I have been comparing this against other weather apps. It looked promising at the start, but the explanation of the composite view is exceedingly poor. Also, I have now driven through two large rain which it indicated as clear sky. Speaking if clear, this is clearly a bad app. I have found both Canweather, Weather Track & The Weather Network to be far superior.
