Image via CrunchBaseCyCamera seem to be a slightly modified version of the stock Android Camera, optimized to upload to a Korean online service called CyWorld.
It has a few effects like LOMO and such that are already in other camera apps. Other than the integration with Cyworld there's really no reason to bother trying this camera app.
Rating: Skip it (unless you're a CyWorld member)
