Built on top of the company's proprietary Gravity Data Service platform, Cubby offers some flexibility missing from Dropbox, starting with its more generous free storage allowance of 5GB; Dropbox gives users 2GB.

Users can also synch data in P2P fashion between computers without impinging on their data limit, although this does mean that at least two of them have to be turned on at the same time.

Usefully, the application allows users to synchronise any folder to the Cubby cloud rather than having to save files to a designated folder containing pre-defined sub-folders, which allows it to work seamlessly as a cloud backup service.

Files saved into the designated folder or folders are sent to the cloud the instant they are saved, with the user being given a helpful visual notification that this is happening. Users decide which files are synched to which devices to avoid expense and bloat; Android, iPad, iPhone, and Mac applications are available.

As with Dropbox, the service allows sharing, including to individuals. The application itself is simple to set up and use and is in good shape. During testing, Techworld experienced no crashes or freezes.
