Instagram is frequently mentioned as one of the many common apps yet to make its way to Microsoft's Windows Phone platform, but as users continue to wait for the Facebook-owned app to make its way to the Windows Phone Store, several competitors have emerged looking to offer snap happy WP users a way of sharing snaps with friends and family. Joining the likes of Eye 'Em in the ranks of so-called 'Instagram killers' comes Photoplay, a relatively new app was published to the Windows Phone Store little under a week ago. Compatible only with the newer breed of Windows Phone (8) at this point, a version for the older WP7.x is currently in the works, and with its clean, sleek interface fitting in rather nicely with the look and feel of the Redmond company's mobile OS, it certainly has great potential.
