Crash, lack alerts, but…

I agree, the latest version crashes a lot. Not sure how much this program will be of help. Waze seems to be more "live" while one is driving & give warnings ahead as one is driving. I thought this program was to send alerts (email) regarding daily routes.
One benefit to this program, is that it does give explanation to some of the sig alerts…

I know before I go, now!

I love checking this app out before I leave my house, or wherever I am! If there is traffic on my regular commute route, I go another way to save time and gas.

It also helped me find a park and ride where I could meet up with coworkers to carpool!

I even added IE511 on Twitter and Facebook. I want ALL the information this service has to offer.

Thanks for real time travel info

I have used this app daily since I downloaded it. The information and maps provided are accurate, clear and simple to use. And IE511 is the ONLY traffic info in Southern CA that has a great graphic for chain control in the mountain communities - finally!!!!
