Documents To GoCompany: DataViz Inc.
If you need to view and edit office documents while on the move then Documents To Go is arguably the best option out there at the moment. The free version allows you to open and view Word and Excel documents, while the paid for version adds in the ability to edit existing documents or create new documents from scratch.
The interface is pretty straightforward and the editing options are good for a smartphone app. For example, you can track changes and there are good formatting options including the ability to add bullet points.
However, the software can be a little bit sluggish to use at times and currently it doesn’t support syncing with the cloud, but to be fair the later issue is due to be addressed in the next release.
Documents To Go is a powerful option for those who need to edit Office documents while on the move.
