Fun and potentially useful project, love it! When I tried it though, it was quite often hard to see whether the bounding box is "really" correct, as it hides what's underneath. Maybe some slight opaqueness could help.

Also, my first image had no bounding box at all. Being met by "Swipe right if the red shape is correctly outlining a building. If not swipe left", it felt like the wording or the UX could be improved by filtering for images that are guaranteed to have such a box.

FYI opaque means not transparent, so you probably meant slight transparency. Or I'm missing something

Positive about the general idea, I hope it works out.

Me too.

Rather confusing on a laptop which was showing "Correct" and "Incorrect" buttons.

Yeah, it's not always easy to see whether it's a building, and whether the outline is correct. Also: should I say it's correct when it's only roughly correct, or should it be perfect? I think you'll get a lot of noise from this.

But according to the presentation, they analyze that noise and manage to use it to improve the data.
