I have a web app that can be easily added to the Home Screen of an iOS device, with a fancy icon.
However, I've noticed that some applications can load what seems like a completely separate page when viewed from Safari before the user adds it to the Home Screen.
This "special" page instructs the user on how to add it to the Home Screen, and when they do, it's a different page.
Notibly, http://darksky.net used to do this before they made an actual app. The Workflows app does this when you add a Workflow to your Home Screen. See screen shot below.
Am I not understanding things correctly, or is there a way to have a different page load when viewed from Safari and another one when it's added to the Home Screen?
