The app is great and accurate, along with the radar information. I normally use two or three app to compare the difference. When compared to Weather Live and the iPhones native Yahoo! Weather, it is about 4 degrees off using Accuweather as a data source.
I know that weather is measured at different spot, therefore temperature should be different as well.
I guess Ill be using this for a while and see its accuracy. For now, Im upgrading it to a 4-star rating
