Inform website users about website app

[phpidz]

I have an android app for my website and I want to inform users who visit the site about it.

I have seen that :

http://m.thehindu.com/

give a very nice option to users who visit the site.

So far I can identify if the user is accessing the site through an android device using :

if( /Android/i.test(navigator.userAgent) ) {

var r=confirm("Dwd android app");

if (r==true)

{

alert("You want to dwd app!");

}


}

I will then use the setcookie() function to find out if this is the user's first visit and store the response.

What I require is an option better than the "plain confirm" I am using to ask users if they want to download the app.

I do not even need a confirm box, I just need to notify a new user that an app is available for the website and give the option of download or skip.
