Ask HN: Which progressive web apps (PWA) do you use, if any?

I really like the concept of PWAs, but I haven't used any in earnest, at least, not as an app. I've never installed a PWA or added one to my home screen, although I'm sure I've visited websites that support A2HS (Add To Home Screen).

I'm curious to hear from you if you use any. What am I missing out on, as a user? It's hard to justify the time spent to build PWA as an app if I don't even use them that way myself.
