Google Docs: Sync, Edit, Share
Google Docs is one of the most versatile apps you can have on your iPhone.
With Google Docs, you can create, import, or share Word documents in the cloud. You can start working on your homework, edit an important document on your computer, and then pick up where you left off on your iPhone while you’re on the go.
Moreover, you can share your files with pretty much anyone. They’ll be able to check the file and read it, or you can let them edit your files so it’s easier for them to make any changes they want — and keep track of those changes so you can see exactly what was done to your doc.
