The Google Drive App for iOS works well for creating, organizing, sharing, and collaborating on documents. I have used it extensively for working on documents in real-time and asynchronously with our faculty learning communities. Unfortunately, you don't always have the same editing and viewing capabilities as you would on a desktop machine or even via the Google Chrome browser on your iOS device. For example, tables don't display within Word docs. However, the app is easy to navigate and a great tool overall.
