title: Is it possible to have an iOS webapp call another regular app to open? Works with Mobile Safari.
body: <p>I am working with my web developers that are stuck on a problem with a Web-app we are creating. </p>
  
  <p>The webapp works great, you add the website to your home screen on the ipad, open it and use the website within the webapp interface outside of safari. </p>
  
  <p>The issue is that we have one function that doesnt work, where when clicking a URL link within mobile safari, it calls an external app (Optiscan- a qr code reader), and then when scanning the code, then returns you to Mobile safari. </p>
  
  <p>The question is - is there a way to call a URL that will open an external app, from within a webapp?  Similar to how it would work from mobile safari?</p>
  
  <p>If so - i am then wondering if an app can be written that calls the webapp to open.  For example if i needed the QR code reader to then re-open the web app and pass it the QR code. </p>
