You must have a problem with this issue because I had to download an app to make it work. After work the accuracy needed to be calibrated and I'm still not sure if that's true. Cheap Chinese junk for 10 cents UPDATE: YES! complete garbage. this thing is everywhere with their testimony. It is packed in a refrigerator with dry items, the temperature and humidity of which I want to know, and the application is BS. I can't use Settings because it requires a Bluetooth connection. BUT IT WON'T CONNECT. Buy another brand.
