An anonymous reader writes "After years of rumors and months of bickering with Apple over revenue splits, Microsoft has finally released an official iOS app for Office 365 subscribers, allowing people to use Word, Excel and PowerPoint on their iPhones and iPads. According to a hands-on report with the software, the Office app has basic functionality, but is missing some key productivity features. 'These include: font options, text alignment, bulleted lists and, again, more color choices, all of which you can find in, say, the Google Drive app.' They say it's a fairly useful addition for current subscribers, but certainly not enough to make it worth the Office 365 subscription fee on its own. 'We can't tell if Microsoft deliberately handicapped Office Mobile for iPhone, or if it's simply saving some features for a later update. (A company rep declined to comment on what we can expect from future versions.) We're willing to believe Microsoft still has some unfinished items on its to-do list, but even so, it's a shame that iPhone users waited this long for an Office app, only to get something with such a minimal feature set. All told, Office Mobile represents a good enough start for Microsoft, and in some ways it's better than Google Drive, particularly where spreadsheets are concerned. Still, it's miles behind other office apps for iOS, including Apple iWork.'"
