iPhone apps: Can I detect whether a user has a certain app installed from a website?
<p>I'd like to use links with special schemes in a website that'll launch an iphone app for a user when clicked (see <a href="http://stackoverflow.com/questions/2095638/iphone-apps-can-i-open-an-app-from-a-link-in-a-website">my previous question</a> for reference).</p>

<p>Is there some way that I can detect, in this website, whether my app is installed? (as in, the app that'd handle my special scheme).
My idea is to decide whether to show a "install our app" link, or a "go to our app" link.</p>

<p>Is this possible?</p>

<p>Thanks!<br>
Daniel</p>
