It just so happens that a fellow Visual Studio ALM MVP, Mike Douglas, has recently released TFS Agile Poker for Windows 8 that works with Microsoft’s Team Foundation Server (or Team Foundation Service).
TFS Agile Poker is a free cross-platform tool for distributed and co-located teams to point (i.e. estimate) your Team Foundation Server backlog. TFS Agile Poker can be used with Team Foundation Service or or your on-premises Team Foundation Server 2010 or 2012 installation using theTFS OData Services.
Microsoft’s Brian Keller selected TFS Agile Poker as his pick of the week in This Week On Channel 9 (starting at 14:14 in the video).
The app is free and is currently available for Windows 8 with plans for Windows Phone, Web/HTML5, Android, and iOS. Read more about this app here.
