Perhaps the second most popular video sharing website, Vimeo, has released their Windows 8 application. With Google essentially ignoring Windows Phone and Windows 8 Vimeo has become a popular alternative.
The Windows 8 app allows users to not only watch videos, but also upload videos directly from the app. The app is beautifully designed, like everything Vimeo makes. You get access to everything you do on the site, including curated channels, and PlayTo integration. The app linked below is called “Vimeo for Samsung,” but if you do a search in the Store you should be able to find the right version for you.
