OneAd is not a preferable app to earn some money. It is very hard to earn money in this app. Its concept is that you have to refer as many people as possible to earn money. Whenever you refer anyone you get some money and if your referred friend refers someone then you also get some money, so it is too hard and time consuming. Its layout and design is not good. It is very hard to understand that. Its features and functions are that if you want to earn money you have to refer friends. I dont think this app is usefull.
