CloudOn, the mobile app for creating, editing and managing Microsoft Office and Adobe documents in the cloud, has today announced the launch of version4.0 of its productivity workspace, which sees it finally rolled out for Android smartphones.

Just to recap, CloudOn taps Dropbox, Box, Google Drive and – since December – SkyDrive integration, to deliver full Microsoft Office capabilities, transforming tablets and smartphones into mobile workspaces capable of accessing Office documents on the go. The app uses cloud technology to connect to Microsoft Office software on CloudOn’s servers, so in effect your device is used as a screen.

While it was already available for Android tablets, with this latest launch, CloudOn now lets users create and edit Word documents, Excel spreadsheets and PowerPoint presentations from their handheld Android device, and compatible handsets for the timebeing will be the Samsung Galaxy S III, Galaxy S II Skyrocket, Galaxy Nexus, Galaxy Note, Galaxy Note II and the Galaxy Nexus 4G LTE, though more will be added in due course.

The Android smartphone incarnation offers similar functionality to the version available on other platforms, and the look, feel and functionality will be familiar to anyone who uses Office on a regular basis.

The app also draws on an Android-customized Microsoft office ribbon, tailored so that touch-reliant functions such as changing the size of a font or enabling tracked changes are made easier.

With version 4,.0, CloudOn is also including landscape mode which, let’s face it, is particularly vital to minimize scrolling in smaller-screened devices.

In addition, the latest smartphone version includes CloudOn FileSpace, which is where users can add notes and view all their activity on a single file, including edits, for real-time updates on documents.

Back in June last year, CloudOn raised $16m in Series B funding to help it move beyond ‘Office for tablets’. This was announced a few weeks after it rolled out in fifteen countries across Europe and in Israel, and then landed in an additional 60 countries globally followed by 12 more in Latin America. To mark today’s launch, the Palo Alto-based company has also announced 3.5 million downloads to date.

The new Android app is live now.
