It is often said that people talk about the weather but no one does anything about it. Well now you can do something about the weather with this app! You can change humidity, dew point, air temperature, and other factors at will. You can create rain, fog, snow, hail, and even a tornado. Dont worry if you are not sure about what you are doing. You will be getting help along the way. This app contains no ads or in app purchases. As a teacher, I can tell you this app correlates well with material typically taught in grades 4 to 9 here in Virginia, USA. But younger children and even adults will enjoy this playful app. This app runs on iPod 5, iPhone 5, iPhone 6, iPhone 6 Plus, iPad 2 and later models of iPads that use IOS 7, 8, and 9. Do not use this app on earlier models of the iPhone, iPad, or iPod.
