The Kinsa QuickCare and Kinsa Smart Stick thermometers can both take oral, underarm and rectal temperature readings. However, despite these thermometers being very different from each other, they both rely on the same technique for getting good measurements.
The most common reason for problem readings is how they’re taken, so please follow these steps to get much better readings every time:
Important Tips for All Readings
- Don’t take any readings after eating, drinking or exercising.
- For QuickCare, always wait for three flashing lines on the display BEFORE putting the tip in your mouth, armpit, etc. Check for these three flashing lines before every reading.
- For mouth readings, always put the tip in your mouth’s heat pocket; under the tongue at the back of the mouth. The temperature in one spot of the mouth can be very different from another (see image below) so always put the tip in the same heat pocket.
- If you or your Kinsa were somewhere with a different temperature (like outside on a cold day) wait until you and your Kinsa are used to the new temperature before taking a reading.
For Oral Readings
For oral readings, always put the tip in your mouth’s heat pocket; under the tongue at the back of the mouth.
The temperature in one spot of the mouth can be very different from another (see picture below) so always put the tip in the same heat pocket for every reading.
For Underarm Readings
Make sure that no clothes are in the way, and that there has been no exercise or bathing in the 15 minutes before the reading is taken. Also, please note that underarm readings are typically 1°F lower than oral readings; this is perfectly normal.
The Kinsa app automatically takes underarm readings into account when calculating the severity of the fever, but it does not artificially add that 1°F to the temperature reading.
For Rectal Readings
Please see follow this post for some very useful information on how to take your baby's temperature rectally: How to Take a Baby's Rectal Temperature
NOTE If you're still getting inconsistent readings after following the Important Tips above, try following these steps:
- Check that your phone is compatible with your Kinsa thermometer by visiting KinsaHealth.com/phones
- If you have a Kinsa Smart Stick, make sure that you have the latest version of the Kinsa app, available for free from the Apple App Store and Google Play Store.
- Again, if you have the Kinsa Smart Stick, you may want to try recalibrating your Kinsa by following these guides for iPhones and Android smartphones.

Written Guide for Kinsa Smart Stick
- Open the Kinsa app on your smartphone.
- 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).
- On the temperature tab, choose your method for taking a temperature (oral, underarm, or rectal).
- 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)
