The video on Help:Editing is relatively up-to-date, so it should look very similar to what the editor looks like for you when editing with a computer or laptop, and the visual editor will come up by default.

There are definitely likely to be some differences on an iPad, as well as other tablets and mobile devices. Unfortunately, I don't have an iPad so I'm not aware of what those differences might be specifically. Hopefully someone else can explain better.
