Zero-True has a built in app mode. You can show or hide cells or the code for cells in each individual cell (by default cells and code are shown),

App Mode Preview

You can preview what your work would look like deployed as an application directly from your notebook. For users that have been moved off of our waitlist, you can also publish to a live URL directly from your notebook. When you publish an app users can interact with UI components and optionally view the code you’ve written.
