How to check if an app is installed from a web-page on an iPhone?

Question

I want to create a web-page, a page that will redirect an iPhone to the app-store if the iPhone does not have the application installed, but if the iPhone has the app instal

As far as I know you can not, from a browser, check if an app is installed or not.

But you can try redirecting the phone to the app, and if nothing happens redirect the phone to a specified page, like this:

setTimeout(function () { window.location = "https://itunes.apple.com/appdir"; }, 25);
window.location = "appname://";

If the second line of code gives a result then the first row is never executed.

Hope this helps!
