When you've installed a web page on your iOS homescreen using Safari, the website becomes a web-app when it utilizes the following meta keys:
<meta name="apple-touch-fullscreen" content="yes">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes"> <!-- this is the only required meta -->
<meta name="apple-mobile-web-app-status-bar-style" content="black">
Using the iosweblinks
code snippet, iOS won't open a new browser for every anchor you click in the 'web view' app.
bower install --save-dev stylr/iosweblinks
You can use this in combination with for example grunt-wiredep to install this package as a (development) dependency.
