Google Opinion Rewards is a loyalty program developed by Google. It was initially launched as a survey mobile app for Android and iOS developed by Google. The app allows users to answer surveys and earn rewards. On Android, users earn Google Play credits which can be redeemed by buying paid apps from Google Play. On iOS, users are paid via PayPal. Users in the available countries who are over 18 years old are eligible. Google Opinion Rewards works with Google Surveys, market researchers make the survey through Google Surveys and answers are received through Google Opinion Rewards by app users. This process provides surveyors with a large pool of surveyees quickly. This "fast and easy" surveying process has been criticized due to contention over the validity of results as well as concern over the privacy and security of the app users' data.
