Agreed very much! I googled and found this tweet with a screenshot seemingly by OP when this was launched in Jan 2022:

This is a tweet thread that also has some more updates, screenshots and GIFs that show the tool in action. Satisfied my itch to know how the product looks/works (I dont have any iOS device so I am not going to use it in any way myself)

As I said in another comment, not sure what you mean, the landing page has a screenshot: https://sindresorhus.com/apps/one-thing/screenshot1.jpg

Are you perhaps blocking external images from loading, perhaps via an ad blocker?

Lack of screenshots is so common with cool stuff that is posted on Hacker News. I am a very visual person, so it completely blows my mind that someone wouldn't include one single screenshot for something they spent so much time building.

But, I have come to believe that most Hacker News users are NOT visual people -- they get that warm an fuzzy feeling about an idea simply from reading about it. That's great, but I'm writing this comment so they realize that there are other people who only get about half way there by reading about it and that screenshots are very important for the other half of the population that they're trying to get interested in their project.

I recently rewrote my website and product screenshots is still a todo. Just follow the App Store button for screenshots.
