Android: Instead of keeping a half-dozen apps on your phone to manage all of the free cloud storage you’ve signed up for, CloudCube is a single app that gives you complete control over all of them. The app supports two-way upload and download, automatic syncing, and more.
CloudCube is a bit like previously mentioned Cloudii, but CloudCube tries to give you both an overall picture of your total cloud storage space as well as the option to drill down to specific providers to see what you have stored on each. Since the app supports syncing, you can use it to keep files and folders on your Android device synchronized with your desktop, or upload and download entire folders at once. Each action is queued so you can manage it independently.
