Grapper is application which is make for online earning. It is not complicated for using and I have no question about this. But it is only usefull for new users which can eran only upto 50-60 rupees hardly. Its design are average not attract peoples to itself.
The developers gives updates to attract people but nothing affect. They divide many portion so that users can easliy use them. It is not usefull for old members, becuse it does not pay anymore. It gives small portion of money at insatllation of application and ask use it for some days then we will give you money. I use alo but it does not pay for it. They pay only small amount of money for only installation not for days.
