Well I don’t know about fake apps but recieved Rs.1 in my account by oneAD. Just you have to make your own network and speard this app in air so you may have a strong network and they will give you money on various tasks.
Although you need contact number and strong relationships with people so they can download your refer app.
I tried but I was not successful to build a network. So I just uninstall the app but I recieved money in my paytm and they charge some money from OneAD wallet to paytm.
So try this app and if you have patience must tried. And can earn upto Rs. 300 per day.
