title: how do I open a native app from a webpage
body: <p>Is it posible to open a native IOS app from a webpage. In my case I want to open <a href="https://itunes.apple.com/dk/app/barcode-scanners/id504201315?mt=8" rel="nofollow noreferrer">https://itunes.apple.com/dk/app/barcode-scanners/id504201315?mt=8</a></p>
