Parent didn't pick a random app, they picked the "top showcase app". Since you don't want to discuss it, despite parent's attempt to select the best example, let's pick something you might discuss: what is your choice of showcase app that few would know it's not native? If it's $5 or less, I'll go download it even if it doesn't interest me. I'll state ahead of time that I've yet to see a non-native app on Android or iOS that wasn't obviously non-native, so I'll be viewing the chosen app with some degree of bias that I would try to keep to minimum. And, hey, if it's any good I'll be happy to rethink my stance, and probably go learn a new framework.
