Google Docs provides you with access to all of your saved and shared documents, and it also gives you the ability to create new ones. Editing is also supported, and you can collaborate with other users on a single document simultaneously right from your phone.
Great interface: This app's interface is fluid and intuitive. All of your documents appear in a list, and when you select one to view or edit, it opens quickly. Each document has individual settings that let you determine whether you want to store it in the cloud or on your device, so it's available for offline editing. All of the editing tools you'll want are also readily available from the document's main page.
Sharing controls: When you share a document with someone else from Google Docs, you can decide what privileges they have. For instance, you may only want some users to be able to view the document, while others will need to be able to edit it or leave comments. This app makes it possible to customize sharing to accommodate these various needs.
Organizationally dependent: All of your Google Docs will show up in one long list in this app. If you have them organized into folders and want to be able to find them that way, you'll have to locate them in the Google Drive app first. Opening them through Google Drive will automatically open the Google Docs app, so you can view, edit, or comment.
This app provides a lot of functionality, including the ability to edit documents offline as long as you've downloaded them to your device. Its dependence on Google Drive is a bit of a drawback, but the apps work seamlessly together, so once you get used to it, you may not even notice the difference.
