Great Temperature Device and Phone App


I bought this Thermometer last year when my husband and I had the flu and all of my Battery Thermometers had dead batteries. Problem is, today when I needed to use it, I realized that it requires a headphone port and my newly updated iPhone 8 doesn’t have a headphone port. I had an IPhone 6 when I bought the Kensa Thermometer.
I did some internet searching and learned that an adapter came with my new iPhone 8 and sure enough I found it still in the box that the phone came in. Now I’m back to using this Thermometer and it’s working beautifully. Maybe this info will help someone else with an updated iPhone. I think IPhone 7 also has no headphone jack. Not sure if it included the adapter though.

I tell everyone about this thermometer! I love it. The fact that it has profiles for the whole family, I can keep track of everything in one place, when the doctor asks when something happened or symptoms started I can actually be confident that I’m giving an accurate answer 👍 (even when loopy from lack of sleep 😴)
Never need to worry about the batteries in the thermometer again 🤗🤗
I have been frustrated on a couple of occasions with not being able to get an accurate reading on the first, or second, attempt. Which is maddening when trying to care for a sick infant. 😠
Overall though this is by far my favorite new baby gadget.

Smart ear stopped syncing temperature to device.


The app was OK at the beginning. Everything worked as advertised, and it was syncing nicely with HealthKit.

As far as accuracy goes, this thermometer is about 2°F warmer than any of my other thermometers, both oral and ear types. Even the Kinsa Stick shows about 2 degrees lower.

I can’t say for sure if it’s inaccurate, maybe all the other thermometers I own have drifted too much. But the fact that it stopped working with the app after 1 day is a deal breaker. The whole point of the smart thermometer is to automatically log your vitals so you don’t have to remember. I’ve had a low-grade fever for 6 months, my doctors want me to track them. Since the ear thermometer appears to be inaccurate and the quality control of both the ear and app seem to be suspect, I can not recommend any Kinsa product.

I’ve tried it on multiple devices and platforms and followed all the instructions on re-syncing the device. The app sees that the device is connected, but it never sensed or logs the readings. After one day, this “smart thermometer” is just an inaccurate $40 ear thermometer.


Save your money, ask your doctor for a recommendation for a cheap and accurate thermometer, and log it the old fashioned way.
