This is a great idea and I also need such an app. Thank you for your suggestion. I can’t allow mold to reappear and I’m glad that I can solve this problem with new technologies. In fact, I already had an unpleasant experience when we had mold in the garage. This is where my workshop is and I’m there every day. I know that this is very harmful to health, so I called a local mold removal company to get rid of the mold. This story ended well for me, but now I have to be more careful and monitor the correct humidity and temperature in the house and garage.
