As part of the latest build of SQL 2016, Microsoft has integrated the DataZen components they acquired into a new Mobile Report Publisher. This functionality is available in the latest SQL 2016 Build CTP 3.2 available for download here.
Using the Mobile Report Publisher, you can create mobile reports easily that render well both through web and native mobile user experiences.
The Power BI App will be the single app for SSRS and Power BI based reports. The support for SSRS mobile reports is now available in the latest build of the IPhone app with Android and Windows expected to follow.
