Bing may not be the top choice you, like a search engine, but there is no doubt that it has some of the most beautiful wallpapers. Microsoft recently released a Windows application that will allow you to use these wallpapers in surface work you.
As of today, there is also an application for Android.
To date, the Google Play Store has only unofficial Bing wallpapers. However, this new application brings the official Bing gallery with extra features.
The application will show you a new image every day that you can set as wallpaper. You can also set the image to change automatically every week or every month.
It also has a section that allows you to explore wallpapers of different categories. You can search by color, country and category.
The application seems to be available in selected countries at the moment, but apparently it is also available for Greece.
Hopefully the company will add more soon functions in practice. Those interested can download it from Google Play Store:
