Google opinion rewards are highest paying app for survey. I started using this app from last 10 days only and I earned 62rs from 10 days.
The survey comes in every nearly 4-5 days and they pay nearly 10rs for just only 3-4 question. As I last gives answer for 5 questions only and they gives me 19rs.
The money will in the form of google play credit which we can use to buy anything from Google play store.
The one thing is not good fpr this app is survey comes in Every 4-5 days or more than that so that we always have to wait for survey.
