There are many apps on Google app store that you would like to have, but you are not sure if they are worth your money. For that purpose, Google introduced an app that can help you get paid apps for free – the Google Opinion Rewards.
With Google Opinion Rewards, you can get credits and earn money that you can spend in their Play Store. The concept is simple: using the app, Google will send you questions regarding your purchasing habits. Every answer you give Google will earn you credit with a maximum of $1 per answered question.
After first launching the app, you would have to answer few questions about you. Then, Google will start sending you survey questions occasionally, at least once a week, sometimes more, sometime less.
The Google Opinion Rewards app is, of course free, and it is available, of course, only for Android users.
I don’t see why you wouldn’t give this app a try. First, you can get the apps you want – for free! With questions ranging from “Which of these logos you like the best” to “When are you next planning to go on holiday”, there’s nothing much to lose. The only thing you can gain is free credits for your favourite apps!
