It has potential, but crashes all the time. Usually get a notification that it's crashing while stuff is loading. Slow response. Weather is never accurate, should've started snowing more than an hour ago. It's got nice features, just needs to be fixed.

This app keeps crashing will not load properly. Also it continues to run in the back ground draining my cell phone battery. The weather forecast and maintenance of highways are always off in reporting the correct weather.
