Written Guide

  1. Open the Kinsa app on your smartphone.
  2. Plug the Kinsa thermometer into your phone. It’s recommended that you use the extension cord that came with the Kinsa as it will likely help return a more accurate reading (and will be more comfortable).
  3. On the temperature tab, choose your method for taking a temperature (oral, underarm, or rectal).
  4. Place the thermometer according to your desired reading location (under the base of the tongue, in the bend of the armpit, or with only the silver tip placed in the rectum)
