So I traditionally do Duolingo on a desktop because I don't like the app, but for Arabic I've been doing it on my phone because of the Arabic keyboard. I don't use the app and I have an iPhone. Anyway, I don't know how to make the slashes above the letters for "a" or below for "i". It leaves me having to write things like "wa" as "و" without the slash. Duolingo still counts it as correct, but I want to do it the right way. Any thoughts?
