First app of 2013. I have been using this tool for a while now and it is rapidly becoming one of my favourite production apps. It turns your Dropbox, Google Drive and Box apps into more than mere viewers, it enables you to open any of the files that you hav on those services and edit them. Within CloudOn you have the ability to create new Word, Excel and PowerPoint documents which in turn can be saved to your Box, Google Drive and Dropbox folders for synchronisation back to your main computers or for sharing with other workers. In short this is an epic tool. The only drawback I can see is that to work it needs to be connected to the net. So if you are out of range of your networks, the app won't fly. But for a free app you should try it out and it is my app of the week.
