I have sent invite to many of my friends and they installed this app.
First, It is hard to earn money from installing 2 apps in this app . You have to install 5-6 apps for this.
Second, Many times You didn’t receive any money even your friends account credited with 2 apps successful. If you would refer multiple friend then you would get 1-2 friends referral.
Third, If your referral earn money next day by installing 2 apps. You would not get any money.
Fourth, You have to keep watching on this app. Because most part of earning, you would earn after a week and It is very hard. If you missed to complete task on exact date you would lose that money.
If things goes fine(and you have to be lucky for this) you would earn money. But I would not recommend anyone this app.
If you have enough free time and free internet, You could earn 30 paytm rupees after struggling half an hour.
