"On its own, Weather or Not is a very nice weather app with beautiful animated graphics. You get the temperature, wind and humidity at whatever locations you set, as well the chance of precipitation. As you swipe your finger on the screen, an animated sun or moon moves to show you predictions for future times. The best part is that the app accesses your calendar and gives you a forecast for future events. You'll get weather seven days ahead; In addition, the app provides you with daily weather reports and forecasts for any upcoming events you have on the calendar, and the app provides a Today extension."
