Microsoft’s Cortana app has been updated for the iPad, offering a native interface for Apple’s tablet device. While the design remains largely the same as the iPhone version, which was released over two years ago but received a UI facelift last fall, the release notes also indicate that the app has gained some performance improvements, launching 20 percent faster than before — an important boost for a third-party voice assistant app, since unlike Siri, Cortana can only receive commands when running in the foreground.
