Cloud Comp was built to provide designers a way to present comps to their clients inside of a realistic device shell. We make it easy by tying straight into CloudApp so there's nothing else to signup for or anywhere else to upload your images to, to get going.
Check out an example of a cloud shot inside of a device.
Note: The authentication in entirely done through CloudApp and nothing is stored on our end.
