Annoyingly, some free iPad weather apps refuse to believe that the UK has any weather (or that the country exists), so AccuWeather gets props for merely working. Happily, AccuWeather also proves to be a decent – if quirky – weather app. The interface is odd (but fun) and there's a 'lifestyle' page that determines how your current local conditions might affect over 20 activities, including dog-walking and stargazing.
