Unfortunately, this app may seem to be the research experiment made by Microsoft Research and it doesn't scream privacy anyway and therefore, it is nothing competitive. Even if you have used this app on Windows Phone, there is still room needed for improvement and at the same time, it has the number of features that perform similarly to the ones from Snapchat. Sure, there was some FTC ruling done against Snapchat and Facebook over privacy violations the last time but it may seem that Facebook is an even worse offender that you may want to bash on. I actually had something in my head about plans to bash on Facebook but then, there isn't anything appropriate so things are scrapped.
This app is for testing purposes and not said to be the core product from Microsoft and in the future, some rival of Snapchat may come up with their own app similar to that that has BETTER PRIVACY PROTECTION.! Certain Snapchat users were already not happy about the privacy violation the last time that they might have decided to ditch it completely in favor of other services but like Microsoft said, Windup for Windows Phone is part of the Microsoft Research experiment that those users can use Windup instead. Unlike Snapchat, the contents posted to Windup may be erased after some time.
