Used it for a week. Installed apps and everything was going well, I was getting 2-3Rs for every app. The minimum withdrawal limit is Rs20. And then the thing happened. At Rs18 it stopped. Not paying single penny even after downloading further 8 apps. And also, no money was credited for referring my friend, they pays Rs20 per referral. But there is no credit in my wallet even after my friend downloaded from my sent referral link. And the cache saved in your phone for this app is of no use because everytime you open this app, it starts building new cache overlaying the previously saved, eating up more of your data usage.
