Documents is one of the most popular productivity apps to land on the App Store in recent memory, and allows its users to open and edit all kinds of files ranging from PDFs and Word documents to music files. All in all, there’s little it couldn’t do, except it was iPad only. Today, Readdle dropped an iPhone-friendly version of its app on to the App Store by updating its previous iPad-only app to make it universal. Best news of all: it’s a free download. The app itself can pull in and manage files from Google Drive and Dropbox as well as sending documents to iCloud.
