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.

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 ,

My High Hopes Are dashed

I had high hopes when I read the description. See all cloud storage files in one app, transfer files from one cloud to another on my iPhone. Boo hiss. First of all, you can only have one account per cloud so if you have more than one Dropbox account, forget it. Then the app says to register for a free rainbow account. Sure, registration is free but doing anything with it costs. Essentially you’re just giving them a free mailing list by registering.
Disappointment. Delete and keep searching

Developer Response ,

What was the problem with connecting to a second (or third) Dropbox account?
When you create your Free Rainbow account you can share files with total size of 500MB (without that account is only 100MB).
We are sorry to see you leave, and we hope you return soon
