Microsoft is internally developing a new Windows Phone app called Revolve. According to the description on its store page, the app is being made to help people start conversations with others in a more meaningful way by delivering information about those they are about to get together with beforehand.
This is not a dating app; it's being made as a business application that combines elements of a calendar and contact manager. ZDNet's Mary Jo Foley reports that it was originally developed as an iOS app as part of the Microsoft Garage incubator program and is now apparently being ported to Windows Phone. So far, neither version has been publicly released.
Here's the official description from the Windows Phone Store page:
Revolve prepares you for every conversation in every meeting. It works in the background to find and display relevant insights about the people you're going to meet. Easily sidestep small talk and spark real conversations that matter.
