Microsoft has published its own 'ephemeral messaging' app WindUp, offering Windows Phone users its take on Snapchat.
Spotted by Neowin, Microsoft Research has released WindUp for Windows Phone 8 and 8.1, giving users pretty much the same time-capped messages that Snapchat has become famous for, but without the app's newer live video chat feature.

According to the app's description, the app lets Windows Phone users "create and share fun, temporary messages and media with friends", including pictures, videos, audio snippets, and text. Like Snapchat, the message expires according to a time limit set by the user.
