title: iPhone/iPad. How do I launch an app from link in Safari?
body: <p>I have an app that I want to be launchable either explicitly when tapped or when a parameterized URL is clicked on on a webpage in Safari running on iPad or iPhone.</p>
  
  <p>Can someone sketch the approach for me and/or point me to the relevant docs? Thanks so much.</p>
  
  <p>Cheers,<br>
