Overleaf's fine, but lack of offline editing, and more crucially, trusting my main working copy to live only on somebody else's computer, is a bit of a non-starter for me.
Plus, call me an idealist, but it feels like a huge step back when a device requires a paid web service to do something that's completely free on a real computer. I don't know that "pay somebody else" should be hailed as the solution to "good software doesn't work on this device".
The Overleaf website is a bit painful to use on an iPad. Hopefully, this will change with the "desktop-grade" Safari announced for iOS 13. Maybe someone already running the beta could test this?
I imagine it will be identical to Safari running on desktop. The Beta also gives you things like page scaling that you have on desktop so you can play with sizing if you like too.
