I don't know about you, but I seem to be accumulating cloud drives. It all started with two free gigabytes of storage from Dropbox, then 5 from Google Drive, 50 gigabytes from Box, and then there was no stopping me. I currently have over 80 GB of storage spread over six cloud drives, and files stuffed everywhere.
I needed an app to combine all of those cloud drives. I found it. It's called "Documents by Readdle" and it's free for your iPad.
