Box is similar to Dropbox in that it provides you with what it calls 5GB+Sync. It allows you to sync up to 5GB of data, making it easier to access and edit files, share content with coworkers, and stay connected while on the go. Updates to documents and spreadsheets are visible immediately through secure content sharing.
There are several iOS cloud storage apps available that help bridge the gap between your mobile devices and your data, among them Dropbox, Google Drive and MediaFire, which were discussed in our Android Productivity Apps slideshow last month. These are all cross-platform cloud storage apps that will work with multiple devices.
