Quickoffice emulates what we think of as an office suite on a desktop. While you probably won’t wish to constantly edit documents on the go, it is definitely an office suite that is robust enough to meet most users’ mobile needs.

In a couple of the cases I was genuinely surprised how well the software worked. Text that I could barely make out was interpreted perfectly. Conversely, perfectly legible text in standard fonts was not transferred at all.

Plus is definitely a worthwhile spreadsheet app. With it you can easily transfer Excel spreadsheets back and forth and edit and open them on both the PC/Mac and the iPhone. While it appears to be well worth its asking price, you still have to ask yourself if its limited support of Excel’s XML file format will be enough for you. If you need full MS Office compatibility, this will disappoint.

DataCase allows you to both store documents on your iPhone and view them on the go.
