The issue is that your criticism is misguided and not very helpful. In your parent comment you totally miss the forest for the trees. Or, the reason why this app has been made in the first place.

Further, your suggestions are inactionable, and again, miss the point. It’s a low effort - “Lol, why don’t you just…”. No, the point is not to find skin cancer. The point is to show a bunch of pictures to people who are interested, and let them see if they can identify worrying skin lesions.
