Fixing the connection between Smart Ear and Android

If you are having trouble connecting your Kinsa Smart Ear, don’t worry!  There are just a few simple steps to getting you on track.


1. Make sure your Kinsa app is logged into your Kinsa account

If you are not logged into your Kinsa app, you won't be able to follow the steps below.

2. Get latest version of the Kinsa app

On your phone's web browser, go to

3. Restart your phone

Note: This is different from turning your phone's display off and on.

4. Turn on Airplane mode

5. Remove your Kinsa Smart Ear from the Kinsa app

  • Open the Kinsa app
  • Tap the ⚙︎ Settings gear button in the top right corner
  • Under Thermometers, tap Smart Ear
  • Tap Forget Thermometer

6. Force close the Kinsa app

7. Reset your Kinsa Smart Ear thermometer

The reset steps are different depending on whether or not your Kinsa has a side button:

  • If your Kinsa has a side button and a large round button on top, hold down both buttons for about 10 seconds. When you see the Bluetooth symbol flashing on the display, wait for your Kinsa to power off by itself, then push the round button to power on and complete the reset. Repeat 1 more time. Open phone bluetooth settings. Find and unpair device with a name starting with "KS_".
  • If your Kinsa does not have a side button and just one large round button on top, remove the batteries, wait 10 seconds, then put the batteries back in.

8. Turn off Airplane mode

9.  Remove your Kinsa Smart Ear from your phone's Bluetooth settings

  • Open your phone's Bluetooth Settings.
  • Turn the Bluetooth switch on (if it isn’t already).
  • On this same screen under devices, look for a name starting with KS_ or AViTA and unpair it.

10. Connect your Smart Ear with your phone

  • Open the Kinsa app
  • Tap the ⚙︎ Settings gear button in the top right corner
  • Under Thermometers, tap Add New Thermometer
  • Follow the on-screen instructions. For best results, choose these options:
  • Enable location services 

Note: The Android operating system, not the Kinsa app, requires location permissions before it will allow the phone to connect with any Bluetooth Low Energy (BLE) device - including Kinsa thermometers. For more details, including the relevant section of the official Android documentation on this topic, please see

  • Then tap Allow only while using the app to give Kinsa access to location information so the Kinsa app can detect when the thermometer is nearby.
  • If your Smart Ear has turned off, press the round button to turn it back on
  • On the Kinsa Thermometer Found alert, tap Allow
  • If you see a Bluetooth Pairing Request alert, tap Pair. Some Android OS versions might show this prompt as a push notification in a status bar.

And you're done! Now you’re ready to take a temperature reading with your Kinsa Smart Ear
