Sharing is cool. We all love to share things, whether it be what we're currently up to on Twitter, or by publishing photos to Facebook from our Windows Phone, it walks hand-in-hand with being intrigued by what our friends are up to. Square, by Lawrence Gripper (the developer behind the BBC News Mobile app), Chris Sienkiewicz and Dave Crawford, is a new solution to contact and image sharing between platforms using QR codes. It's a fairly simple concept, but ingeniously executed.
Square will enable the user to grab an image from the Pictures Hub (providing choice of camera roll, SkyDrive or Facebook albums) and share it to another device with a generic QR code scanner. Not only that, but contacts on the Windows Phone can also be shared to another device with a scanner (and support for vCards). If you're one who detests carrying around business cards as much as I, Square also sports a contact card option for yourself (basically choosing "you" from your contact list to import your details), which can be pinned to the home screen for quick access and turns your contact information into a handy QR code (in vCard format).
Of course, the app wouldn't be complete without a scanner. Square comes kitted out with the tools to scan QR codes and import images and contacts. It all works flawlessly, and the UI (although there's not much depth) is simply gorgeous. When will we see Square on the Marketplace? In the next couple of weeks. To see the app in action, head on past the break for a quick demonstration.
