After acing these life-saving features, now smartwatch companies are focusing on adding a temperature-monitoring feature to the watch.

Reportedly many big companies are working on this feature and we are already seeing this feature in many of the new smartwatches.

So, If you are interested in getting a smartwatch with a temperature monitoring feature, this guide is for you.

Here is an article that I have written about Best 10 Sports Apps For Smartwatch To Get Live Games Score In 2023.

In this comprehensive guide, I’ll the smartwatches which can track your skin and body temperature. Let’s get started.

Can A Smartwatch Tell Your Temperature?

If you have asked me this question a couple of years back, it wasn’t possible but in 2023, we have many capable smartwatches which can effectively track your skin and body temperature.

The basic tech for monitoring temperature varies from company to company but it all started with the legendary Fitbit Sense. This watch was launched as a health smartwatch and it comes with a built-in EDA sensor which basically tells the body about skin temperature changes. The watch uses for stress tracking and sleep tracking.

The second generation of Fitbit Sense has been launched recently but it doesn’t mention the EDA Sensor. It’s quite possible that the watch might be still rocking the EDA sensor underneath but it’s also possible that the company might have switched to other sensors. 

While I can’t tell you specifically about the type of sensors they are using, I can definitely tell you about the smartwatches which can monitor your temperature.

How Does Temperature Monitoring Work In Smartwatches?

When it comes to smartwatches, they use special sensors which basically record the thermal activity on the skin level. 

It’s worth mentioning here that these watches work very similarly to thermometers and both types of devices check the skin temperature of your body.

However, when it comes to smartwatches, you can’t check your skin temperature the way you check your heart rate. The technology hasn’t reached that level of maturity yet but soon we will be able to check our skin temperature using a smartwatch on demand. 

For now, these smartwatches use these skin temperature monitoring sensors for stress tracking and sleep tracking. It’s still a very useful feature and it can give you a lot of useful insights about your body.

Top 5 Smartwatches With Temperature Monitoring

Now that you know how smartwatches track your temperature, Let’s have a look at the smartwatches which can track your skin temperature.

1. Fitbit Sense 2

Let’s start with Fitbit Sense 2 which is one of the best smartwatches that comes with a temperature monitoring feature.

The skin temperature monitoring feature was originally available only on Fitbit Sense but now many Fitbits including Fitbit Sense 2 come with the skin temperature monitoring.

The watch tracks your skin temperature when you sleep and it’s currently only available for sleep and stress monitoring. When you sleep, the watch will take a sample of your skin temperature and set it as a baseline. After it set up the baseline, the watch will show the variation from your baseline skin temperature on the Fitbit App.

If we look at the other features of Fitbit Sense 2, you get useful features such as ECG, EDA Scan for stress management, AFib detection, Heart-rate tracking, and other promising features.

So, if you want a full-fledged health smartwatch with tons of useful features, Fitbit Sense 2 is a solid option.

2. Samsung Galaxy Watch 5 Pro

Samsung Galaxy Watch 5 Pro is the newest smartwatch in the Galaxy Watch collection and it’s also one of the very few smartwatches that come with temperature monitoring sensors.

Like Fitbit Sense 2, Galaxy Watch 5 pro also uses skin temperature monitoring sensors for sleep tracking and it provides the temperature variation along with the sleep stats.

In terms of other features, the Galaxy Watch 5 Pro comes with other promising features such as BIA sensors which can read your skeletal muscle, body fat, body water, and other metrics. Similarly, it’s also equipped with an ECG feature which you can use to do an ECG test directly on your wrist.

So, if you want a premium smartwatch with a temperature monitoring feature, Galaxy Watch 5 Pro is a solid option.

3. Apple Watch Series 8

Apple Watch 8 is the newest Apple Watch and it comes with many promising features including a temperature monitoring function.

Like other smartwatches on the list, Apple Watch Series 8 also establishes a baseline temperature of your skin, and then it tracks the variation from your baseline temperature when you sleep. It’s important to note here that the Apple Watch 8 will take 5 days to determine your baseline temperature and once it determines, it will start showing the baseline temperature variation on the app. 

The Apple Watch 8 is also equipped with other useful features such as crash detection, fall detection, ECG, Heart-rate monitoring, advanced sleep tracking, workout modes, and more.

So, if you are an iPhone user and you want a watch that can monitor your temperature, Apple Watch Series 8 is an ideal option for you.

4. Fitbit Versa 4

Fitbit Versa 4 is another premium smartwatch that comes with a skin temperature monitoring function. In terms of features, Versa 4 is not as feature-rich as Sense 2 but it covers the basics well and offers a decent set of features.

One of the major differences between the Versa 4 and Sense 2 is that the former doesn’t come with a dedicated EDA Sensor. However, the watch uses other sensors of the app to provide the skin temperature variation when you sleep.

Another difference between both watches is that the Versa 4 doesn’t have the ECG feature which means that it won’t alert you for AFib and other heart-related problems. 

However, it comes with other regular features such as stress management, sleep tracking, heart-rate monitoring, workout tracking, SPO2 sensors, and more. 

So, if you don’t want to spend a lot of money and want a decent smartwatch under $200, you should consider Fitbit Versa 4.

 5. Apple Watch Ultra

Apple Watch Ultra is the first premium rugged smartwatch by the company and the company has aced almost every aspect of it. The watch comes with a rugged build and tons of useful features including temperature monitoring.

When it comes to the overall mechanism of monitoring body temperature, it’s similar to what you get in the Apple Watch Series 8. The only major difference here will be the set of features. In Apple Watch Ultra, along with the regular features, you get a bigger and brightest display, titanium case, and 36 hours of battery life.

So, if you are interested in getting a rugged smartwatch with body temperature monitoring, you can’t go wrong with Apple Watch Ultra.

Can I Check My Body Temperature From A Smartwatch On Demand?

Like Heart-rate or ECG, you can’t check your body temperature on demand because this feature is still in the early stages and for now it only operates passively. However, I’m very confident that it will change in the future and we will be able to check our body temperature from our smartwatches on demand.

Can Apple Watch tell your Temperature?

Apple Watch Series 8 and Apple Watch Ultra come with two dedicated temperature sensors which regularly take temperature samples when you sleep and provide you with temperature variation from your baseline temperature. Temperature monitoring is currently only available in the newer versions and old versions such as Apple Watch 7 and earlier don’t have this feature.

Can Galaxy Watch Tell Your Temperature?

Samsung Galaxy Watch 5 and Galaxy Watch 5 pro come with a temperature monitoring function that allows you to check your body temperature variation in your sleep. Like Apple Watch, temperature monitoring is passive and you can’t check your body temperature on demand.

Can Oura Ring Tell Your Temperature?

Oura Ring 3 comes with a dedicated temperature sensor that notes your skin temperature every minute and provides you with detailed insights into your temperature. It’s the only wearable other than smartwatches, that can tell your body temperature.

Can I Tell My Body Temperature Using Ticwris GTS?

Ticwris GTS is a relatively less popular smartwatch that claims to detect the body temperature in real-time. For this purpose, the watch uses the temperature monitoring device (thermistor). I did some quick research on the thermistor and found that it’s the type of resistor that can detect the change in Temperature.

I also checked the reviews of Ticwris GTS users on various platforms and many users were satisfied with the ability of the watch to measure Temperature. Some users also voiced their concerns about the watch, but the number of them was lower.


Temperature monitoring is a great feature and I’m pretty sure that we will great improvement in it over the next few years.

In this guide, I’ve shared the top 5 smartwatches that can tell your temperature. I hope that you found the guide useful and if you have any questions, please let me know in the comments.
