Back in last December, Google Apps business subscribers got to play with Quickoffice for iPad for free. Now Google Apps users can use the Quickoffice app for editing Microsoft Office documents on iPhone and Android as well, and yes it’s available for free.
With the app you will be able to edit, create and view Word, Excel and PowerPoint documents and then save or share documents through your Google Drive account. Google Drive might become capable of natively opening those types of files and editing them in the future, but until then Quickoffice is what you will need.
If interested, Android users can download from here and the iOS version is available here. As for those of you who don’t have a Google Apps for Business account, you can check out Quickoffice Pro which is available as a paid app priced between $15 to $20. So, are you downloading it already?[Source]
