Microsoft launches Bing Rewards for Android and iOS, Windows Phone version on the horizon
What’s Bing Rewards? It is Microsoft’s way of thanking you for using Bing search - which, as you may know, isn’t immensely popular, not even among Windows Phone users (who have Bing as the default search app). Bing Rewards allows you to earn credits just by searching with Bing. These credits can be redeemed for gift cards (from Xbox, Amazon, Skype, Dominos or Fandango), or they can be donated “to a local school or charity of your choice.”
At the moment, Bing Rewards is available only in select markets (including, of course, the US). To start using it on your Android or iOS phone / tablet, point your mobile browser to the first source link below (you can sign in using your Microsoft or Facebook account).
