Is there any way to detect if a user has added a web app to their home screen?

Question

I'm using an iOS springboard "Add to home screen" notification on a site, which appears depending on certain user information. I just don't want my popup to trigger if the user has already added the web app to their home screen.

Is there any way to detect this?

Answer 1

You should be able to see if fullscreen or in a browser using

if (navigator.standalone) {
    alert ('Running full screen');
} else {
    alert ('Running in a browser');
}

Or an alternative approach would be to look at the window size, to see if there are any chrome around.
