With Windows Phone 8.1, Bing Rewards are integrated into the built-in search app. You can earn Bing Rewards for all the searches you do on your Windows Phone device. However, there is no way to manage the Bing Rewards you earned in a convenient way. Today, Microsoft released the Bing Rewards app for Windows Phone devices.
Use the Bing Rewards app to manage your account, earn and redeem credits, enter sweepstakes, and find new ways to earn every day.
Pin the Bing Rewards app to your start screen to track your available credits and complete daily offers. Redeem credits for great rewards from Amazon.com, Starbucks, Xbox, and many more. Check your current status and find out how to get to the next level.
Download it here from Windows Phone Store for free.
