Until now, the iOS Drive application only allowed users to view Google Document word processing files. However, the new version adds the ability to create new word processing documents, edit existing ones, format their text and see edits being made by other users in real time.

Meanwhile, the Android application now lets users add and reply to comments, as well as view tables in Google word processing documents.

Also new in both the iOS and Android Drive applications are the ability to view Google Presentation files, as well as create folders, move files into them and upload files.

Next on the upgrade agenda is giving users of the Android and iOS applications the ability to edit and collaborate in real time on Google Spreadsheet files.

The Web-based version of Drive that can be accessed via Windows, Mac OS and Chrome OS computers has these and other features not yet available in the mobile applications.
