FUTO keyboard does.

That’s the closest I’ve seen so far. It’d be perfect if it also hid checked items in sub groups without all sub items needing to be checked but I can definitely work with this. Thanks!

The one feature I’m still struggling to find in a notes app is the ability to automatically hide checked items in a list.

The option mentioned in this article wants to charge me to even consider getting any checkboxes so back to FUTO notes I go till I find something better.
