Kabuki Vision’s DocsPortal 1.0 is an app designed to make it easy for you to browse, search and view files stored in a Google Docs account on your iPad. Files can also be e-mailed, imported and exported from within the app.
DocsPortal automatically downloads and stores Google Docs files right on your iPad, so that you can access them even without being connected to the internet. Whenever an internet connection is present though, DocsPortal will sync with Google Docs, so that the latest file updates are always available.

DocsPortal 1.0 can be downloaded from the Apple iTunes App Store for $3.99 in the Productivity category. In order to use the app, you must have a Google Docs account.
