Traffic shows car traffic information around you (via GPS) in just one click. By default, app tracks your position so it's great navigation assistant.
There is an option to turn OFF tracking, so user can look at other places around the world to check the traffic info.
It uses Google Traffic map layer, so traffic info is available for United States, United Kingdom, Ireland, Taiwan, Shangai, Beijing, Austria, Belgium, Czech Republic, Denmark, Germany, Ireland, Israel, Luxembourg, Netherlands, Poland, Slovakia, Spain, Switzerland, Sweden, and more.
The app has ultimately plain and simple UI, leaving all the screen for the map.
