Mobile timer?

Question

JavaScript

Hello!
I have the following problem.
I'm making a simple timer at the end of which a sound appears. (on js). olga-marchenko.com.ua/timer
The problem is that when you minimize the application, the timer stops running and the sound does not play. Can you please tell me how to fix this? What are the options? For mobile phones I use this plugin, that is, the site is loaded from the desktop as an application. cubiq.org/add-to-home-screen
I would be very grateful for any help)
