Google Opinion Rewards app is a survey platform. Users can earn Google Play credits or money by answering quick surveys provided by the Google team.
Earn money in fragmented time. Offer your opinions and advice, and help Google to improve its products and services.
Now users can link their Gmail accounts to the Google Opinion Rewards app. Users can share their receipts to their Gmail address and earn more money.
You can redeem your credit by tapping the "Play Store" button on the home screen of the app. You can also directly shop with the credits in the Google Play store.
Maybe you buy items with credits instead of money in the Google Play store. Please check your transaction records in the Google Play store. It is also possible that your credits expire. The credits received will expire one year from the date you get them.
