App to help you know if you have COVID19

So you can literally look at google pictures of skin diseases to find out what your skin condition is, and get an idea of what's wrong with you. I think this would save time and money. I've gotten skin conditions that are easy to fix, but then you go to the doctor and then have to wait for results and stuff like that. Note that Google pictures is not 100% accurate but this is just a fun idea.
