Oh really? Is that what it says? Let's take a look:
> All I wanted was a way to click on things in a photo and have the number go up.
Those are the requirements. That's what the app is supposed to do.
I don't see "a tool for counting red dots" anywhere. The closest thing is this passage:
> It's stupidly simple: upload an image, click to drop a dot, and it tells you how many you've placed[…] But somehow, nothing like it existed.
You linked to an app that places its own markers (by way of ML) and then gives you a count of those—not a count of the ones that you put down. That so obviously fails the requirements.
Pass in your image with red dots, and the red dots will be counted by the ML-counting thing just fine. It's a minor variation in approach to solving the problem, and that's OK: When confronted with a problem, people often jump to specific solutions too quickly, and miss out on better or more general approaches. This is quite pertinent in this specific case, as well - you can ask the ML-counting thing to count the rectangles instead of the dots, and perhaps save yourself all the clicking in the first place.
