Can the apple watch check the body temperature?

Does the Apple Watch offer the possibility to measure body temperature? Unfortunately no! Discover why and how to get access to this data somehow.


Last updated on Dec 11, 2022

This article was first written in 2021, and, at that time, measuring the body temperature with the Apple Watch was still impossible. The unveiling of the Apple Watch Series 8 and Apple Watch Ultra in September 2022 has somehow changed it. The long-awaited feature is now available. Do not expect to obtain a measure of your body core temperature at all times and whenever you feel a bit feverish. Just like the Fitbit Sense Series, the Apple Watch Series 8 and Ultra will only detect your temperature when you sleep after establishing a baseline for a couple of days. Once the baseline is established, you will get the variations from this baseline. Measuring body temperature is tricky, and Apple rely on two sensors to detect your wrist temperature and the temperature of the environment you sleep in. One step at a time, smartwatches are getting smarter, and we welcome this new temperature analysis feature to the Apple Watch family. We found that this addition was one of the key innovations as long as sensors and wearables are concerned for 2022.

The Apple Watch is considered the most advanced smartwatch in today’s market. A lot of people opt for it for good reasons. This is because it comes with various advanced health tracking features like heart rate monitoring, blood oxygen level monitoring, electrocardiogram (ECG) App, and so much more.

But can the apple watch measure the body temperature as well? That’s what we’ll be talking about in this article so that you’ll be able to get a definite answer to that question.

Can the Apple Watch Measure Temperature?

The honest answer is NO. The Apple Watch can’t track or take body temperature by itself since it doesn’t have a dedicated thermo-sensor. However, many people may agree that it’d be an excellent addition if Apple decides to add this much-needed feature to the latest smartwatch, the Apple Watch Series 6.

Not that this is impossible or technically complex. For example, the Fitbit Sense includes this feature and other important health metrics like an FDA-cleared ECG, heart rate, blood oxygen saturation, stress level, etc. Unfortunately, the temperature is not instantaneous but is the average of the measures recorded while you sleep.

If you are an Apple Watch user looking for the ECG Smartwatch or to measure your blood oxygen levels, then Apple Watch Series 6 can be the right and the most optimal option for you, but if you want to measure your body temperature on the go, then we recommend that you look for another option.

The iPhone can not measure the temperature independently either. Somehow be used to track the temperature measurements obtained with other devices. For example, many Apple Watch apps are available in an iOS store that can monitor the temperature. But note that none of these apps can automatically record the body temperature. They all have to be paired with an external device to provide accurate results.

You may use Apps such as ThermoWatch+ to record the temperature readings manually into a smartwatch so that you may check it later.

How About The iPhone? Can You Take The Temperature With It?

As we mentioned, the Apple phone can’t take the body temperature, but you may pair it with a compatible digital thermometer to record the body temperature directly on the iPhone. It can be convenient for those looking for an easy way to monitor their health or the evolution of a fever.

Once the data is entered, you can view the data for a specific period of time. Additionally, it displays temperature data in a graphical format so that you or your doctor can see a temperature trend over a particular period.

If you’re looking for a digital thermometer for an iPhone, then the Kinsa Smart Thermometer can be the one you should consider. We ranked it as our overall best smart thermometer for 2021. Taking your temperature and synchronizing the data with your phone can become quite addictive and be part of your quantified life’s daily routine.


In short, the Apple Smartwatch can’t automatically detect body temperature. Instead, you may couple it with a compatible digital thermometer so that you can record the body temperature automatically.

Smartwatches will not replace Thermometers anytime soon, even though some now offer the possibility to measure the skin temperature. Among them, we can mention the TicWatch GTH, the Amazfit GTR 2e, or the Fitbit Sense.

For tracking your fertile days, the Ava device allows the recording of the temperature while asleep. When combined with other parameters, your fertile days will be estimated with a high degree of accuracy.
