Not showing the UI prompt if the user has installed the web app

[gedw99]

I tested his on iOS using the test link.

if I do the install and then reopen the link it will proof me again.

is this by design ? Is there a way we can check if it’s already installed ?

If not, maybe we can add a Boolean into the session storage that is set to true when they do the install ? Just brainstorming this . Tough problem

The way to do this maybe to use a url scheme ?

hi @gedw99 thanks for posing this question.
If you open the bookmarked page, it will check it is installed and not show the dialog.
However, if you open the non-bookmarked page, it cannot check because the bookmarked and non-bookmarked pages use completely different caches. I believe this is the case you've encountered.
i've never found a way to check if its already installed in the non-bookmarked site, but if you have any ideas let me know!

as a heuristic, you can set maxModalDisplayCount = N so that the modal goes away after being shown N times

You got it exactly , bummer there is no common .

https://ntfy.sh/ has the same problem I noticed .

https://ntfy.sh/app Is where you can try it . It shows it’s state , about installed, in the top left of the menu .

crazy idea . Fingerprint the user and store the needed state on server . It’s aweful I know but best I can think of ..

Sorry couldn't find a better client side solution. Thanks for helping to discuss!
