The apps, which are part of Microsoft's Office 365 productivity suite, currently hold the first through fourth spots in the most downloaded free apps charts as of Saturday afternoon. Microsoft Word is No. 1, while Excel, Powerpoint and OneNote round out top four.
That's a good sign for Microsoft, which has been working to bring the apps to Apple's tablets for years now. Especially when competing apps like Quip, Evernote and Apple's own office apps have been available on iPads for some time.
