There are tons of posts about installing webapps on the iOS (iPhone, iPad) though Safari, but none of them answers if it can be done though javascript or a html link with specific "rel".
The scenario is that I want to user browsing to the web site, to be able to simply click a huge install button in the middle of the screen, then iOS would of course ask for verification of some sort, and then the app will be installed...
Is this possible or I would have to force the user to click on the + sign?
