To be somewhat fair to the author, if the device's own setting app is slow and janky, you can't expect better from an application you download.

There are tablets out there, no name brands but also Lenovo branded ones, that are a complete waste of natural resources. I've had the displeasure of using a few of them in store demos and they couldn't even get video to play back at a consistent rate.

You're lucky to get an app working at all on that crapware, let alone at a smooth 60fps.

Strangely enough, I've had smoother experiences with some Chrome web apps on an old Android tablet than the native device UI is capable of providing. This thing was mid-range and outdated when I bought it years ago and it still runs Android 7 through LineageOS relatively well, but nobody is going to make that thing have a smooth experience. I'm hoping for the powervr video driver to be ported to postmarketOS so I can flash a lightweight Linux distro on there.

Sometimes, though, when the wind is just right and the stars align, Chrome is doing a smooth 60fps animation on that thing and I honestly can't figure out how they've manage to do it. It's impressive to see what modern web browsers are capable of squeezing out of slow hardware.

Total agree on all your other points. I don't think this stuff matters for this specific developer because of the nature of the application, but it's not great general advice.
