Frontback started with a great idea: why not make a photo app that takes a snap from your phone's front and back cameras at the same time?
That way you can share what's happening and your reaction. But great ideas aren't enough, and despite attracting two million users over two years in operation, Frontback is shutting down.
The idea won't be dead, as the phone developers will be adding Frontback (such as Sasmung) stylized option to their cameras.
