Welcome to Android Central! I don't think there's an app that will do what you're trying to do. Syncing app info across different devices and the cloud is dependent on those individual apps. For example, if you use Google Keep to write a few notes, then if you install Google Keep on another device (that is logged into the same Google account), you'll see those notes show up there as well. You will also be able to see those notes if you go to the Google Keep website on your computer (again, if you're logged in with the same Google account).
However, if you manually create a folder and place some photos there, you won't be able to automatically sync that folder to all of your other devices, because you created that folder on your own. On the other hand, if you used Google+ Photos to upload those photos, then they would be easily accessible on any of your other devices by accessing your Google+ Photos cloud albums.
