Six months in, Google’s apps still don’t fully support iOS 9
Google updated its Docs and Sheets productivity apps on Tuesday to support the iPad Pro's larger screen resolution. As you might recall from our iPad Pro review, iOS apps that don't properly support Apple's guidelines for resolution-independent apps will look stretched out and slightly blurry on an iPad Pro, much like an iPhone 5 app would look larger and blurry on an iPhone 6.
The problem, as pointed out by MacStories and elsewhere, is that the apps still don't support the Split View multitasking features Apple introduced in iOS 9 when it was announced in June and released in September. This is especially noticeable because productivity apps are the best fit for Split View multitasking—it just makes it easier to grab text and other data from one place and paste it down in another place when your apps are side-by-side. And it's not just Docs and Sheets that still haven't gone all-in on iOS 9. Few of Google's apps support Split View, and the YouTube app doesn't support the Picture-in-Picture multitasking mode either.
