Yah, the tricky bit is safari access. I'd love to put a bunch of time into using service workers, push notifications, and so on to make an app-like experience for my users (it's a forum / social network thingy for teachers), but mobile safari really puts a crimp in those plans. Instead I have my own homegrown cache and other hairy tricks that are nonstandard, but work on safari.
