How to open ios app using url?

Question

I want to open my ios app using URL schemes. I am able to open app using this. But I want if app is not installed then app store should be opened where user can download app. Is this possible? How can I do that?

EDIT Explaining question step wise:

1. I have a mail in my inbox with a url.
2. I click on URL then i. If app is installed in phone, app will launch. ii. Otherwise app store will be opened to download app.

Thank

I handled it via my server side code:

if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {
location.replace("com.myapp://");
setTimeout(function() {
                if (!document.webkitHidden) {
                    location.replace("https://itunes.apple.com/app/xxxxxxxx");
                }
            }, 25);}
else if ((navigator.userAgent.match(/android/i)) || (navigator.userAgent.match(/Android/i))) {
location.replace("https://play.google.com/store/apps/details?id=packagename&hl=en");}
else  {
location.replace("http://www.example.com");}

I put this in my www.mysite.com/download page & share this url via campaigns.
