We support iPad about as good as we can, with stylus pressure and some tricks to avoid slowdowns due to the high input rate. I actually did the ink in Excalidraw too, so it at least worked last time I touched it! But the difference between iPad Safari input latency and native latency is gigantic, really heart breaking to work on. Not sure if a native wrapper would improve things. If I did a native app, it would likely be a minimal drawing app for handwriting only. I recently started prototyping an Android app with the new low-latency jetpack ink APIs and they’re fantastic, beating perceived latency vs iPad even on a 60fps screen (Daylight).
