This is a very nice app which gives you for doing nothing, just surf the web as you did it earlier. The only change is that you have to do it in another browser named mCent browser.
This browser gives recharge instantly. You will get rupees 1 for just 10 clicks per day, which you might do in just a minute.
I am using this app for about 10-15 days and already earned 30 rupees.
The only thing bad is its work space is very small.
