I see https://gladdendesign.com/collections/paper-apps at the top of http://hhn.domador.net/2025/02/06/07/ (snapshot courtesy of the HN snapshot tool). I’m sure this has been posted to Hacker News before, but I’m glad to see it surface again.

As much as I love paper and pen, web versions of these apps would be good, but I can see the appeal of the notepads.
