Microsoft has released a new app in the Windows Store for x86, x64, and ARM devices that allow you to view Office 365 reports. Simply tag the reports in Office 365 and the reports will be available on your Windows tablet or other Windows 8 computers.
In addition to allowing you to view the Office 365-generated reports and tagging your favorites, you can also share reports with others using the sharing component built into Windows 8.
You can pick-up the Power BI app using the following link, or just searching the Windows Store for 'Microsoft Power BI.'
