Snapchat has a checkered history on Windows Phone with its fans on the platform enduring, then finding immense frustration. There has never been an official app for Snapchat on Windows Phone and that doesn't look to be changing any time soon despite the outcry from the community.
Until recently, Snapchatters on Windows Phone had third-party solutions to choose from, such as the excellent 6Snap. But after Snapchat clamped down on unofficial clients hooking into their systems, all third-party apps were removed. And so the situation is now one of no apps and a lot of frustrated users.
