Waze is a community-based traffic and navigation app. I had used Waze before but it was not so useful in earlier days as not many people were using it in India. But now Waze is quite active in India.
Using Waze you know what’s happening on the road. Even if you know the way, Waze tells you about traffic, construction, police, crashes, and more in real-time. If traffic is bad on your route, Waze will change it to save you time.
I am loving it and now it is becoming my navigator replaced by Google Maps. I think that itself tells a lot about the quality of Waza.
You can download it for Android from https://play.google.com/store/apps/details?id=com.waze
