I\'ve been looking for a way to open a native iOS app from the browser. I found a decent solution here: Is it possible to register a http+domain-based URL Scheme for iPhone

The right way to do this is to use Smart App Banners: https://developer.apple.com/library/ios/documentation/AppleApplications/Reference/SafariWebContent/PromotingAppswithAppBanners/PromotingAppswithAppBanners.html

If your app is not installed, the banner will let the user install it. If it is installed, it will open the app, and you have a way of specifying custom URL arguments to pass to the app.

Here is a solution that works for me:

var timeout;

function preventPopup() {
    clearTimeout(timeout);
    timeout = null;
    window.removeEventListener('pagehide', preventPopup);
}

function openApp() {    
    $('<iframe />')
    .attr('src', appurl)
    .attr('style', 'display:none;')
    .appendTo('body');

    timeout = setTimeout(function() {
            document.location = appstore;
    }, 500);
    window.addEventListener('pagehide', preventPopup);
}

For solving this and avoid no wanted iOS safari alert I've used a different approach handle also an iframe but without jquery and listener events. It works perfectly.

    var iframe = document.createElement("iframe");

    iframe.style.border = "none";
    iframe.style.width = "1px";
    iframe.style.height = "1px";
    iframe.onload = function () {
        document.location = alt;
    };
    iframe.src = nativeSchemaUrl; //iOS app schema url

    window.onload = function(){
        document.body.appendChild(iframe);
    }

    setTimeout(function(){
        window.location = fallbackUrl; //fallback url
    },300);

use iframe.
```
$('<iframe />').attr('src', "appname://").attr('style', 'display:none;').appendTo('body');
```

I'm using meta refresh as fallback because this works without javascript. This code works in iOS and Android.

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <meta http-equiv="refresh" content="1; url=http://www.facebook.com">
    <title>Redirecting..</title>
    <script>
    function tryOpenApp() {
                var iframe = document.createElement("iframe");
                iframe.style.border = "none";
                iframe.style.width = "1px";
                iframe.style.height = "1px";
                iframe.src = "fb://feed/";
                document.body.appendChild(iframe);
    }
    </script>
  </head>
  <body onload="tryOpenApp()">
  </body>
</html>

For me this does the job:
```
window.open(appLink, '_system')`

window.open(appstoreLink, '_system')
```
Works for android and ios. If the first one can't be opened the second one is called without alert or something. Otherwise it just opens the app.
