iPhone and iPad Web App Startup Images

・1 min read

In order to avoid having a blank white screen when launching a web app, you can use a apple-touch-startup-image. This is displayed momentarily while the web app is loading.

There are a number of link tags to target all iPhone and iPad devices which you must use. But there’s also a very important thing to not do, and that is to not use width=device-width on the viewport meta tag because this will letterbox the viewport and it will not work.

Here is the gist (Update 28 Apr 2013: Added apple-touch-icons):

<!--iPhone and iPad Apple Touch Icons -->

<!-- iPhone Non-Retina -->
<link rel="apple-touch-icon-precomposed" sizes="57x57" href="apple-touch-icon-57x57.png">
<!-- iPhone Retina -->
<link rel="apple-touch-icon-precomposed" sizes="114x114" href="apple-touch-icon-114x114.png">

<!-- iPad Non-Retina -->
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-72x72.png" sizes="72x72">
<!-- iPad Retina -->
<link rel="apple-touch-icon-precomposed" sizes="144x144" href="apple-touch-icon-144x144.png">

<!-- Do NOT use width=device width because it will letterbox viewport. -->
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
