Apps: Basic Settings - Apple touch icon

The Apple touch icon is an icon that you can add on your iPhone or iPad to quickly go to the website. In Photoshop you create a file of 192x192 pixels with a resolution of 72px, you make the icon (without rounded corners) and save it as .png. You can upload it at Apps > Basic > Settings > Apple touch icon.

On the iPhone or iPad you go to the website and then click on the share button and click on 'add to home screen'. Your icon is now on the home screen of the iPhone or iPad.
