Can a webpage appear in iOS Safari without any Safari UI even if someone visits the URL in the browser? I have a web app added to the home screen of the iphone. is it possible to open this web apps added to the home screen if someone visits a URL in safari.

i'm aware that the web app added to the home screen is actually running in safari, but i want to open that web app .. is there any custom iphone specific URL to call a web app ?

Example : i bookmarked www.example.com on my iphone and the app has all the required META tags to run as a webapp. now if someone visits www.example.com in the browser, it should detect if the app has been added to the home screen and if it is, it should open it.

is this possible ?

The whole point is that i want to open the app without any Safari UI even if someone visits my URL in the browser.

P.S i know the use of window.navigator.standalone - but it does not help in Safari.
When you launch a web app by entering the URL in Safari it runs in the Safari app. But when you launch a web app from the springboard (home screen), it runs in different Safari app. Hence the lack of Safari UI in the that case. What you want isn't possible. And it's actually a good thing because the Safari UI offers option you might need to use ('mail link to this page', 'Tweet', 'Print', ...).

What you want to do may be possible through some kind of hack if you jailbreak, although I doubt it.
