Google has updated their Google Drive app on iOS today to include built-in document editing. The new app version also includes support for collaboration, so more than one user can be editing the document at one time. Users have access to formatting options from a prominent bar placed across the top of the screen.

One user of the new app notes that it seems to be a web interface as the keystrokes don't immediately appear on the screen. He also notes that the interface is very similar to Apple's Pages app, though the typing features that delay previously mentioned.

The iOS App page lists the following as changes:

• Edit Google documents with formatting and collaboration
• Edits to your Google documents appear to collaborators in seconds
• Richer Google presentations with animations and speaker notes

Having editing and collaboration directly in the app is an extremely useful feature, especially the collaboration part. Users can pick up the app for free from the Apple App Store.
