You can see an example of this in action at the following URL: http://www.tmumc.org (active at the time of writing 05/10/17).
When you first go to the site, you will see an overlay that shows up, pointing them towards the App store app.
If you close this button, it sets a cookie on the users machine.
So then, if you refresh the page, the overlay will no longer show up for 24 hours.
