What is the user-agent string for the Safari home screen?

Is there a unique user-agent string specifically for Safari on IOS that identifies it as being in "Home screen" or "app mode"? I've observed a bug on IOS8 where the browser window appears incorrectly, with the time and battery information overlapping the webpage content, and a black border appearing at the bottom. It seems like the top panel present in IOS7 was removed without proper testing, leading to this issue.

In order to address such problems in the future, it would be helpful to have a distinctive "App mode" user agent that could serve as a temporary fix. Is there a user-agent string designed for this purpose, or am I left without any workaround options?

I've noticed that this problem only occurs when the webpage is in "full screen". Interestingly, it doesn't manifest on sites like Stack Overflow but does occur on Slashdot.

Answer №1

Instead of sniffing the user agent, it is recommended to check the 'navigator.standalone' property for a more reliable method. This property will return 'true' when your web app is launched from the home screen.

Regarding the black bar at the bottom issue (which seems to be a bug), it would be wise to ensure that your content can adapt to the presence of a status bar, similar to how native apps handle such scenarios.

Answer №2

Presented below are 2 user-agent strings for IOS 8:

Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/538.34.9 (KHTML, like Gecko) Mobile/12A4265u

Mozilla/5.0 (iPad; CPU OS 8_0 like Mac OS X) AppleWebKit/538.34.9 (KHTML, like Gecko) Mobile/12A4265u

I trust this information will be useful.

Answer №3

When in HomeScreen mode, both iPad and iPhone omit "Safari" from their user-agent string.

For example, when viewing a page in the browser on an iPhone:

Mozilla/5.0 (iPhone; CPU iPhone OS 9_3_2 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13F69 Safari/601.1

But if the same phone is viewing the page in a WebApp:

Mozilla/5.0 (iPhone; CPU iPhone OS 9_3_2 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Mobile/13F69
