Molome is coming to Windows Phone 8. Molome is actually an app that is like Instagram with the added feature like badges. It is not a new app. It is actually available on other OSes like Android, BlackBerry, Symbian or Meego.
Initially, it was thought that it could be (again) a Nokia exclusive app because of this photo.
Now, it is made clear that Molome is available for all Windows Phone 8 devices. They may make one for Windows Phone 7.X devices but will concentrate on the latest OS first (according to the information from WPCentral).
Similar to Instagram, the Molome app enables users to share their photo on Facebook, Twitter, Tumblr and many more. It also has an additional “boasting” feature of badges. You can collect badges for “achievement”
There is no timeline on when it will arrive but I guess it will be soon.
