You can always copy an app. That option is under settings for the app, and then in App Management.
But the copy of the app is a separate app that has its own separate life. Obviously any changes you making a copy of app are just for testing purposes and would have to be re-implemented in the live app from scratch.
The sandbox feature is not widely used by my clients but in theory it does let you do your changes in the sandbox and then promote them to the live app.
