Microsoft announced Microsoft Rewards app for Microsoft Reward program on Xbox. The app is currently available for Preview Alpha. It can be downloaded from your Xbox One Insider Hub on your Xbox One console by joining the beta through the Insider Content page. If you don’t see anything as such you should hold your breath for little more as Microsoft still is the process of rolling this to more Xbox Insiders in coming weeks.
The app is currently available in the United States only albeit Microsoft confirmed that they are working to make the app available to all the countries where Microsoft Rewards is available.
The app will simply show Store gift cards, points you have earned from searches with Bing and several Microsoft product purchases. If you are already a member of Microsoft Rewards program then all you need to do is log in to the app with your Microsoft account. Those who are not a part of Xbox Rewards obviously need to become a member of the program.
As we all know that Microsoft will migrate Xbox Live Rewards account to Microsoft Rewards sometimes in June or July. The company clarifies that the migration or Xbox Live Rewards account will remain intact even if you join the beta programme and create an account. All your achievements will be added to Microsoft Rewards account on completion of the migration.
