Labelbox, a free iPhone app by Stepcase, has been quickly climbing up the App Store charts lately thanks to a neat functionality that enables you to apply colored tapes to your photos to make them prettier, and share them online with your friends.

Labelbox is free, but doesn’t have any sort of ads and comes with a polished interface to edit your photos. Once you’ve loaded a photo from the camera roll, or shot a new one directly within the app, you’ll be able to swipe on it to apply a “tape” that can also contains a written description with a custom font. So, say you want to add some style to your photos or a few words to better describe the subject, Labelbox has got you covered. You can choose from a variety of colored tapes (some are really cute), and even mix them to create a “frame” to place around your photo. To remove a tape you simply have to tap & hold, but you can shake your iPhone to clear the whole screen.

You can share your photo creations to Twitter, Facebook and tumblr through the Step.ly network. The best results are achieved when you combine the filters offered by an app like Instagram with the colored tapes of Labelbox.

The app is a free download in the App Store.
