I love the idea of this and echo the comments on good UI, but would need to see more convenience for it to be worth switching from my existing system. I currently use Workflowy for this, which has web/native desktop apps for easily typing out lists that can be completed on the phone like this, crossing them off in the same way. Workflowy don't have an apple watch app yet though so you have an advantage there. Also I would change the "crossing out" action to work on clicking anywhere on the row, whereas now it only works on the radio button or label. That's a big pain for right handed people with one-word items.
