How to find the ID / Program name of a phone app application in web form?-CodePudding

What I am doing

I am creating a web form that is being used as a QR code to open an application installed in an android / IOS phone. When the user scans the QR code the phone shall run the web form and the web form will check if the application is installed inside the phone, if the application is installed, the web form will open the application, if not it will open the google play store/app store web page based on which OS system is being used.

My problem

Right now my problem is that I do not know what is the name/id of the application to trigger/open it, the only thing I about the app know is that it is called Rymtime inside the setting and also the home screen. The application's google play store link is at

What I have tried

I have tried to put its name directly into the code:

window.location = "Rymtime://";

I have also tried to put the "id" thingy found inside its google play store website "www...id=com.time2clock.wai.timeemployee"

window.location = "com.time2clock.wai.timeemployee://";

My Code

I created my code based on this stack overflow question.

Below is my code:

<body>
...
            <button name="data1" type="button" onclick="getOS()">Click</button> //I use button to test out the function
...
</body>
     
<script type="text/javascript">
         function getOS() {
             var userAgent = window.navigator.userAgent,
                 platform = window.navigator.platform,
                 windowsPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE'], //as I do not own an Iphone I use this to test out the IOS part
                 iosPlatforms = ['iPhone', 'iPad', 'iPod'],
                 os = null;
             if (iosPlatforms.indexOf(platform) !== -1) {
                 ios();
             } else if (windowsPlatforms.indexOf(platform) !== -1) {
                 ios(); //as I do not own an Iphone I use this to test out the IOS part
             } else if (/Android/.test(userAgent)) {
                 android();
             }
    }
    function ios() {
        setTimeout(function () { window.location = "https://apps.apple.com/my/app/rymtime/id1447217174"; }, 25);
        window.location = "Rymtime://"; //I do not test this part because I do not own an Iphone an I am using window to see if the code is being executed, I only check if the website above is runned
    }
         function android() {
             setTimeout(function () { window.location = "https://play.google.com/store/apps/details?id=com.time2clock.wai.timeemployee"; }, 25);
             window.location = "Rymtime://"; //The application is not executed thus it redirect to the play store page.
             }
</script>

Btw is the location of an application installed inside a phone the same as the others? Like this:

somefile\somefile\packageName

Or something like this:

Username(differ)\somefile\somefile\packageName

Thanks.

I am not sure what it is for IOS but I found out that I can just add &launch=true at the end of the URL of the application's google play store page to launch the app if it is installed.
