Create an access to your clients:

Before, you have to create access for your client to your admin panel and to his app.

Then, invite your client to login with the access you sent him. Once he is logged in the previewer app, he will see only his app, unlike you because when you log in to this previewer app with your credentials you are able to see ALL the apps you've created.
