Fix the connection between Smart Ear and Kinsa Smart Stick app for iPhone

If the Kinsa Smart Stick app on your iPhone isn’t getting readings from your Smart Ear thermometer, don’t worry! This guide will fix that for you.

Before you begin, first check:

  • Have you tried restarting your iPhone? 
    • The old turn-it-off-and-on-again trick is still remarkably useful for fixing Bluetooth glitches.
  • Was the thermometer connected with any other mobile devices?
    • Kinsa thermometers can only connect with one device at a time. Before making a new connection, old connections should first be removed from other devices; both from the settings inside any Kinsa apps, and from the list of paired Bluetooth devices in the other devices' own Settings app.
  • Do you have the newer Kinsa app on any device? 
    • If yes, you’ll need to remove the Smart Ear from within that newer rKinsa app (you don't have to delete the app itself) to avoid interference with the Kinsa Smart Stick app on your own device.

If you made any changes after these checks, the problem might already be fixed. To test, open the Kinsa Smart Stick app first* then take a new thermometer reading. If the reading appears in the app, you’re all set! 

But if the reading doesn't appear, follow these steps:

  1. If the thermometer is on, hold down the round button to turn it off.
  2. Open your iPhone’s Settings app > Bluetooth > Turn on the Bluetooth switch.
  3. Below this switch, if you see a paired device starting with KS_ or AViTA > tap its button > Forget This Device
  4. Tap < Settings in the top left corner > wait a few seconds then scroll down and tap Kinsa Smart Stick > Turn on this Bluetooth switch too.
  5. Restart your iPhone. More details.
  6. Turn on Airplane Mode. More details.
  7. Open the Kinsa Smart Stick app > More > Smart Ear > Forget Thermometer > OK
  8. Force close the Kinsa Smart Stick app. More details.
  9. Reset the thermometer.
    • If the thermometer does not have a side button, remove and reinsert the batteries.
    • If the thermometer does have a side button, hold down both buttons until the Bluetooth symbol is flashing on the display. Then hold down the round button to power off.
  10. Turn off Airplane mode. More details
  11. Open the Kinsa Smart Stick app > More > ⨁ Add New Thermometer > Smart Ear
  12. At the New Kinsa app available alert, tap Later
  13. When asked, push the round button on the thermometer.
  14. On the next alert, tap Connect thermometer

You’re done! The connection between the thermometer and the app has now been fixed. Test again by opening the Kinsa app first*  then taking a new thermometer reading.

But if your iPhone still isn’t receiving readings from your Smart Ear thermometer, we're so sorry and we're here to make it right. Please tell our Customer Happiness team that you’ve already followed this "iPhone to Smart Ear troubleshooting guide" and we’ll take care of the rest!


* If the thermometer is within range (about 10 feet) and the Kinsa app is open before a new thermometer reading is taken, that reading will appear in the app immediately. But if the app is not open before new readings are taken, those readings will be sent to the app every 10 to 15 minutes to save the thermometer's battery life.
