I'd like to find a good Weather app but I just don't think that WeatherBugg cuts it. First of all, it's European coverage is terrible - so, I expect that the people that love it live in America. Secondly, it's interface is really badly designed. It doesn't tell me what it's doing (when it's fetching data), so I don't know if the app has hung or not... it doesn't have any obvious 'click here' for more info buttons/icons, etc.
Overall, I find it a very amateur effort... IMHO
Have you tried the Accuweather App? I find it works much better than Weatherbugg. It has a great radar feature too that animates the clouds and storms.
