There are a series of meta tags you need to use depending on whether you are trying to view your app on a web browser or as an app icon within an operating system. Here are the versions I typically include in a web project. They typicallly cover most of my needs, but there are an extensive list of icons you can provide depending on the platform you are targeting.

rel="apple-touch-icon"

<link
rel="icon"
type="image/png"
