Your requirements are different from mine.

I AM fine with a native app that only works on a single OS. Cross-platform is not necessary, or even desired.

"Doesn't require any installation" doesn't even enter into my evaluation. The last time I cared about that was when my computer didn't have a hard drive.

The UI/UX of Boards is to my liking. Several design choices resonate with how my brain works.

That it stores its data in iCloud is to my liking.

That it doesn't require a browser is to my liking.
