Customer Reviews

Poor accuracy is new-- what gives?

I have used this app successfully for a couple of years. Until recently it wasn't perfect but certainly got the job done. Over the last few months it's consistently wrong! Since it's a recent development I have to assume they are no longer getting reports from the same sources, but for all of us that makes it pretty much useless. FWIW, I am in South Orange County, so that's where I'm seeking info. Perhaps it is better in other regions?


The app worked well the first few months, but then started behaving erratically, such as not responding when I tapped on it to view incident details, or showing yellow/light orange for roads that are basically a parking lot. It's become flaky and totally unreliable.

Almost always wrong

I rely on traffic apps for my commute. It's almost always wrong. It says there is traffic when the road is wide open. And there are supposedly updates quite frequently but I don't get it. I'm deleting the app. - Live traffic reports
