Microsoft has a TwinsOrNot app for Windows Phone devices

Microsoft's been big on facial recognition lately. After promising that the technology can be used as a log-in option for Windows 10, it launched a website that guesses your age based on your features ( and another that takes a stab at whether the people in two different photos are twins ( More recently, the company has launched a mobile app version of TwinsOrNot for Windows Phone devices. You know, for those times when you quickly need to know if your power brows really make you look like Cara Delevingne. Or if you and your BFF are slowly morphing into a single person like Zooey Deschanel and Katy Perry in the image above.

Just like the website, the app allows you to upload your own pics straight from your device or to search Bing, in case you're specifically looking for celebrity photos. TwinsOrNot was built using a set of APIs under Project Oxford within just a few hours to prove that it's easy to incorporate machine learning into apps. It was designed to get better the more you use it, so long as you allow it to keep the photos you upload, but you can always choose to have it delete your images after use.
