Documents by Readdle is now available for the iPhone. Now a universal app, Documents lets you read Office documents, annotate PDFs, edit text files, listen to music, look at photos, and more. Across the bottom of the screen, there are four sections, along with access to the built-in web browser. Documents stores all of your files, from music to PDFs, and you can move files from Documents to iCloud by tapping the “Edit” button and selecting which files to move.
