This app is a great way to learn all the Indian road signs. It's a good way to practice before you get your drivers license, but it is also good for tourists and other people who want to learn more about the road signs.
The layout is simple with a quiz as the main object. Take the quiz and see how much you know. There's also a good summary at the end, so you can see how much you got correct and wrong, and you can also see what specific answer you gave.
There's also a statistics page where you can see how many questions you answered, how many you answered correctly and your average score.
