Android Candy: Cloud Bonding
Although the title might sound like some new-fangled tech jargon, I'm actually referring to a fairly simple Android app called "Unclouded." If you're a Dropbox user who also has things stored in Google Drive, Unclouded is a single interface to multiple file syncing backends. Sure, it's not horribly difficult to open multiple apps to work with your cloud-based files, but it can be inconvenient.
Unclouded also has some neat features like locating duplicate files taking up precious space in your cloud storage, and it can do previews for most media types. Unfortunately, the free version limits the number of accounts you can connect to, and it also disables useful things like sharing, moving, renaming and deleting files. Thankfully, the premium features are a few bucks at the most, and even without them, the app is elegant and useful. Check it out today at the Google Play Store: https://play.google.com/store/apps/details?id=com.cgollner.unclouded.
