Every earning app’s content is the same… Wanna know what??? Rubbish!
Again for every earning app, it is Rubbish!
So, you think yourself superior than other developers here???
Grow up, man! We are living in 21st century.
Accordingly to me an Earning App is an app which is made by 
people like you who actually can’t think beyond money.
BTW, can I know how much you have earned from these apps till date?
