Normally there are many apps to earn reward or Money by filling submitting some surways.
Basically this app GOOGLE OPINION REWARDS is also same app like that. But there are no surways to complete.
Nearly a year ago this app was launched and at that time I installed and registered this app , and completed one surway and that is profile section. From that time till now there are no special or other surways to complete . I installed this app today and tried. this app is not updated or I can this app is useless.
If You not believe in me just try this app by downloading it from play store and one thing is that this is a Google app. that was the not believing thing.
