Depends on the user’s expectations, I guess. The demo you linked does not feel close to native yet. Lots of reflows, small shifts, inconsistent rough animation… even for a web app it’s not smooth enough (iOS Safari)
You guys are technically correct, but also dead wrong with your outlook
They're trying to make a useful app for humans, not trying to win the HackerNews Award for Excellence in UX. If accepting a little unfixable edge case jank makes their goal way easier to attain, they're going to end up with a much better app overall
I am not trying to nitpick - just giving my honest feedback. This submission is not for a technological breakthrough that I would admire from a theoretical perspective.
This problem has been solved many times over the last decade or so. So claiming that _this_ is the future and not the more established (and smooth!) solution has to be supported by at least some evidence.
UX is a real thing. Any user that feel your app is crappy, slow, inconsistent, ugly, breaking OS paradigms, janky. Will just dump it, and just get another one (there are plenty) Users are the real judges giving you the Award of Excellence, any minute they keep using your app
If you care about UX, you should make native apps.
