One of Google’s lower-profile apps, this has a lot of value for those who do a lot of work on mobile devices. The app differs from Google’s other major office productivity app, Google Drive, in some small but key ways. QuickOffice’s main appeal is that it works with Microsoft Office file formats, even if they’re not stored on Google Drive. So if you get an e-mail with a Microsoft Office file you want to edit, you can open it in QuickOffice right from the attachment. Using Google Drive, you can only read Office documents, even if they’re stored in your Google Drive.
QuickOffice also offers you a little more flexibility in general — it’s a stronger editor than Google Docs and has an easy interface that makes it simple to use. It’s not going to replace your computer for composing long documents, but it is a great tool for when you’re on the road. There are some, however, who will be disappointed with QuickOffice — namely those who used the product before Google acquired it. Since the acquisition, the app has lost some features, namely integration with services such as Dropbox. Free, for iOS and Android.
