How many hours have you spend on searching for a file among the cloud services and their folders?

How difficult is to transfer your data from one cloud service to another?

The Rainbow application is a powerful tool to transfer data from one cloud service to another:
* While you browse your files / folders on any provider / account, you drag & drop those that you wish to transfer / share.
* Then, you select the target service and target folder that you would like the selected files to be transferred to

More importantly, the Rainbow application offers a simple interface to search for files. A powerful search engine will return all the files that match the key-word that you typed. Then, you can long press on a file to learn more info about that file or you can drag and drop that file to the file cabinet to transfer it. Finally, the Rainbow application supports multi-accounts

Rainbow supports the following thirteen cloud services:
- Box
- DropBox
- Egnyte
- Hubic
- Google Drive
- iDrive
- MediaFire
- ShareFile
- OneDrive (old SkyDrive)
- OneDrive for business
- Sugar Sync

With the Rainbow app, you can copy, move or delete files from one service to another service or from one folder to another folder on the same service.

- Passcode protect your data
- Create and edit text files (simple text editor)
- Use the camera or the photo library to take pictures

Ratings and Reviews

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.

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.

Needs some work.


Great idea, but it needs some work. I was able to get Dropbox and Google Drive accounts on board and functioning but the app would crash every time when signing up SkyDrive. I will continue to hang on to the app with hopes that it can be refined and made fully functional.

My only other qualm is with the packaging...I get the pun (rainbow to connect the clouds) but dislike the theme and the color scheme, and I'll leave it at that...
