If you're an iPhone user, you probably didn't know that Google Drive has a fairly usable, built-in document scanning feature.

Now, the feature's got even better. According to Google, the scanner now has a dedicated button in the lower right corner. It also has an automatic capture feature, helping you get the best scan faster. The camera viewfinder will help you to position your document for the best possible scan, and there's an option to import documents from your camera roll.
