Amusingly enough, Fastmail is a web app wrapped in WKWebview and Protonmail is a truly native app.

Based on comments over in /r/protonmail there's some redesigns coming for the apps that should hopefully improve on the creature comforts.

I hope this is true because I like the privacy aspect of protonmail and would pay for it in that case.
