The Android app can now be downloaded for free from Google Play, providing the Android smartphone is running Android 4.0 Ice Cream Sandwich or later.
As with the recently launched Office for iPhone app, users must be subscribers to the cloud-based Office 365 in order to create and edit Word, Excel and PowerPoint documents, and then save these to SkyDrive.
Non-subscribers are able to open the app but it will find that it is almost useless. Unfortunately, there is no option to upgrade to Office 365 when in the app.
The bad news is that the Office app is only available on certain devices and in some regions. The application doesn’t currently support Android tablets and can only be downloaded by people living in the U.S. Microsoft expects to add more countries in the coming weeks.
Office 365 costs $100 a year and allows users to install Office apps on up to five devices, including PCs, Macs and smartphones. The cloud service is expected to come to Apple iPads and Android tablets at a later date.
