App that integrates cloud storage services?

Is there an OS X app that integrates cloud storage services?

I have Dropbox, Google Drive, SkyDrive
I have looked at:
http://otixo.com - it is a service, not an app
http://cumulo.azurewebsites.net - it is for Win 8

Any ideas?

What kind of storage are you looking for? Some OS X programs integrate iCloud storage, but as far as I know that's largely Apple's own applications that do that.

Sorry, I didn't phrase the question very well.
I am looking for an app to manage multiple cloud storage services in one "dashboard" similar to the ones I mentioned.

I think I just found what I was Looking for:
