Once you view the website over any PWA supported browsers you can see a prompt to add the web app into the homescreen
I managed to find the instructions on the PWA site and saved my site onto my phone’s Home screen, however when I reopened the app, there was no such prompt.
I’m currently using the Safari browser on an iPhone 6. I also have the back end of my WordPress site up on my desktop on which I’m using Google Chrome.
