Google Play Store is the best place to get apps, games, books, music, videos and more for your Android phone or tablet. Thousands of them are free. For some of them with premium features or ad-free version you need to buy a paid app or games. Buying books or renting movie also cost you money. So, you need to have Google Play credit or fund your account with debit / credit card to be able to buy. Google added PayPal as a payment support for Play Store contents to involve more users.
Don’t have Google Play credit in your account? No problem. Google released a free app called “Google Opinion Rewards” in the Play Store. This is one of the nice Google apps available in Play Store for Android. This app asks you to answer some short surveys in your phone or tablet and offers a small amount of free Google Play credit. You will get around a year to spend it before the balance expires.
The surveys are not always available. When there is a new survey available the app will notify you. Unfortunately, the Google Opinion Rewards app does NOT work in every country. e.g. Hungary
Using the app is very easy. You just need to install Google Opinion Rewards app from Play Store and answer some basic question about yourself. Then, connect your Google Wallet account with this app. The app is small, only 1.89MB and has been downloaded more than 500,000+ times. The latest version released on 28th of August 2014.
I have used this app for few months and got merely few pounds as reward. And, the surveys are not that hard or long. Some of them comes with YES or NO answer. Based on the survey and your answer you receive some free Google Play credit to spend in Play Store. Why not try the app and get some free Google Play credit if it is available in your country.
