It works.

Before I got my head wrapped around how to access and see my files, I had a dozen Sugar sync duplicates loaded, with no way to delete the duplicates. I didn't even count the Dropbox dupes, had to delete the app and start over. The search feature was the key for me to see my clouds files. Hated this app at first, but its gaining acceptance. Oddly enough, I can't see in Rainbow a file that is on Drive that I just transferred but is not openable in Drive. It's a plaintext file. I'm thinking at this point in time its me, but maybe not. A higher caliber brain cell is needed to figure that one out.

Great cloud manager

I love the app easy to use once you know everything Is at easy file transferring between cloud services must have app if you have multiple cloud services

Had a problem with Dropbox but thanks to the quick response and yes the update fixed the problem.

I do wish I could hide the other cloud services that I dnt use and keep the ones that I use when I open the app

Developer Response ,


thank you for the rating. Currently you can change the order by dragging them. But, this is indeed a nice feature. Could you please sends an email so that we can further discuss this feature? Thank you

Rough around the edges but functional

This app is ugly. It is not pleasing to use BUT should be commended for the engineering and operations it performs. I can move, delete, and copy data between all of the services I use and because of that I don't even worry about getting all the other official apps. Get this person a UI designer.

That said, I did have issues signing into my Box account (took me to the App Store and then did nothing after I hit log in) but other accounts worked fine.
