Smart Stick: Setup or Reading errors on iPhone

If you have a newer iPhone without a headphone jack, you may just need to connect the pieces in a particular order instead of following the steps listed below.

First, please make sure you are connecting the pieces in the EXACT order laid here:

How to use the Smart Stick on an iPhone with no headphone jack 


But if the problem persists, follow the steps below:

There are a few issues that can interfere with the setup or temperature reading of your Kinsa Stick thermometer on an iOS device, but don’t worry – we will take you through each possibility until you’re ready to go.

Using about 3 minutes of your time, this is what we will check for:

  • Physical device connections
  • iOS music settings:
    • EQ – Not “Late Night”
    • Volume Limit – Off
  • Audio Settings
    • Mono Audio – Off
    • Audio Balance – centered
  • Update to the latest Kinsa app
  • Recalibrate Smart Stick
  • Reboot smartphone

By checking each of these, we can almost guarantee that your problem will get solved - and stay solved! So let’s begin.


For iPhones without a headphone jack (7, 8, X, XR, XS)

Since your phone doesn't have a built-in headphone jack, please make sure you are connecting all the necessary pieces in this EXACT order before continuing on with the steps below.


Connection Problems

Sometimes connection problems happen between the app and the thermometer. To be sure there aren’t any, the following tips should be applied.

  1. On your iPhone, double-tap the home button.
  2. Swipe the Kinsa app up to close it.
  3. Next be sure the headphone jack is clear of lint. You can clean the headphone jack by gently using a toothpick to clear it out.
  4. Finally make sure you listen for a ‘click’ when you use any of these combinations of plugging your:
    • Kinsa into the black adapter (setup only)
    • Black adapter into the phone (or Lightning adapter iP: iPhone 7) ((setup only))
    • Kinsa into the phone
    • Kinsa into the extension cord
    • Extension cord into the phone (or Lightning adapter: iPhone 7) 

Audio Settings

Now that everything is clean and connected, let’s check some of your smartphone's audio settings as these can cause setup and temperature reading issues as well.

NOTE: We will be calibrating / setting up the thermometer after checking these settings. If setup was completed once before, don’t worry. Calibrating the thermometer a second time can only help with temperature reading accuracy.

  1. Open your iOS Settings.
  2. Scroll down and tap on Music.
  3. If “EQ” is set to “Late Night”, tap on it and switch it to anything else. You can change this back after the Kinsa setup.
  4. Go back to Music. If “Volume Limit” shows that it is “On”, tap on it and drag the slider as far to the right as it will go. This will turn it to “Off”. You can change this back after the Kinsa setup.
  5. Go back to Settings, and then navigate to General > Accessibility.
  6. Scroll down to “Mono Audio”. If turned on, switch it to off.
  7. Next scroll to the audio volume balance slider (or tap “Audio Balance” to access it).
  8. Move the audio balance slider to the far left and release it.
  9. Move the slider back to center. It should snap into place once you're close enough. Make sure the slider is completely centered. If it is even slightly off like the first image below you’ll need to try again. The second image is centered.

NOTE: In order for Kinsa to work every time you take a temperature reading:

  • “Mono Audio” needs to be off
  • Audio balance needs to be centered


Update the Kinsa App

Finally let’s update the app in case it is an older version (skip these steps if you just installed the app).

  1. On your phone, go the App Store.
  2. Tap on “Updates” (lower right).
  3. Scroll down to “Kinsa” (if shown) and accept the update if available.


Recalibrate your Kinsa Smart Stick thermometer

Open the Kinsa app, navigate to More > “Add a New Thermometer”. Do not touch the volume during setup.

If the app doesn’t appear to sense the adapter/thermometer, make sure the flat side of the thermometer is even with the surface it is resting on. You can even give the adapter and thermometer a quarter or half turn each. Turning the audio plug(s) may help the phone detect the connection and initiate setup.

If still an issue, restart your phone and try setup once more (leaving volume untouched).

After set up completes, try a reading but:

  • Avoid eating or drinking any liquids, exercising, taking showers or baths, or smoking for 15 minutes prior to use, as these activities can cause mild elevations in temperature.
  • Leave the thermometer still while you take a temperature.
  • Don’t change the phone volume.
  • Wait about 30 seconds between readings. Kinsa takes its best readings from room temperature, so back to back readings can confuse it.


Reboot Smartphone

Lastly, we recommend rebooting or restarting your smartphone to clear out any junk settings or glitches which may be causing trouble.

This should resolve your setup or reading issue. If not, please contact us by Submitting This Form and we’ll be happy to help!
