MCent app is an app from that, real money can earn. It gives some apps, when install these apps. They give money within 24 hours when a task is completed. It also ask to refer a friend to earn extra money. I also use this app from last 3 months. I install all apps. But they does not give more apps. When I install mCent they give good amount of money, but now they give only small amount of money which is not enough.
