I created https://kidsclock.quaxio.com/ to help my kid learn to read analog clocks. He mastered the skill before I finished the app (works fine on desktop, not yet fully functional on mobile). I love to create these kinds of very simple webapps to keep kids busy at e.g. restaurants.

I bet there are tons of similar analog clock apps out there but mine is 100% free and open source (https://github.com/alokmenghrajani/kidsclock), without any tracking or ads.
