What the fuck is a TellSpec?
It's a device (spectrometer) that you aim at food, or at a wall, or in the air, and it will tell you what's there. So if you're allergic to soy, you aim it at food on your plate, and it will send the information about the food's ingredients to your smartphone. Or if you're allergic to a specific type of mold, you can aim it at a wall and it will determine what's there.
