Used to work great


I got this app for winter driving information. Ever since the last update that is the information I cannot get on the app. Some of the time the option is available in layers but if you click on any other option (like plow information) it disappears and you have to completely reload the app to get it back. The app is useless if you can’t get the information you need when you need it most.

Difficult to find winter driving


Like the other reviewer said, it’s hard to find winter driving. This is the main reason to use the app. Also the pop ups confirming if I’m a driver or not are annoying. Take a note from Waze and use the accelerometer to determine if I’m actually moving or not.

I love this app. Just wish it had cameras to low flooding areas. Where the Raccoon and Des Moines river meet. Along the Des Moines river and Raccoon river. Walnut Creek, South Skunk George Flagg Road, Water Works Park, Fluer Drive, Merle Hay Road and Johnston. Airport, etc
