Google Opinion Rewards is an app that credits you with money you can spend on Google Play, for answering a few questions every couple of days.
Answer quick surveys and earn Google Play credits with Google Opinion Rewards, an app created by Google Consumer Surveys.
Getting started is easy. Download the app and answer basic questions about yourself. We'll then send you surveys around once a week, although it may be more or less frequent. You'll get a notification on your phone when a short and relevant survey is ready for you, and can receive up to £0.60 in Play credits for completing it. Questions can range from, "Which logo is best?" and "Which promotion is most compelling?" to "When do you plan on traveling next?"
For example, I have £15 in Google Play credits after 4 months, and getting a handful of questions perhaps 2 or 3 times per week.
