Box for iPhone and iPad by Box, Inc.
This app is awesome because I was at the right place at the right time. I received 50 free GBs of cloud storage with this provider and it is awesome. That is the main reason that I use it.
I can store all of my pictures there and not worry about them. They made the best change to their service recently by allowing you to download the program and use it just like Dropbox now. Major improvement and I believe that move saved the company.
Just another way to keep our Life Organized, Simple and In-Sync.
