Official Add To Homescreen plugin displays a callout to mobile users inviting them to add the website to the home screen.
I think it's not working on IOS 8.
So far this is working well! I did notice a small bug that's throwing a notice on line 29 in /includes/public.php wherein you're trying to pass a $slug var to the constructor (which you're not using). Looks like something that was meant to be removed. :)
Have used the standalone version of this previously, so kudos to the developer for creating this helpful plugin!
One thing that would be handy is if it was possible to rename the title that shows under the icon on my iPad. At the moment it takes the site title, but that's long for SE purposes and ideally I'd just like to have a short title displayed. Is that possible? I don't know?
Either way, this is super-cool!
Just starting to play around with this plugin and everything is working great so far. I really like that it offers statistics too. I look forward to exploring the options further.
