Smartwatches are no longer pricey step counters. Instead, most of the most recent ones can record blood pressure, blood oxygen level, sleep monitoring, and even identify stress via electrodermal activity (EDA) sensors that detect changes in perspiration levels.
Temperature monitoring may appear to be a simple add-on, yet respected manufacturers such as Apple do not include skin temperature measurement on its Apple Watch Series. Even though this feature is long-awaited and was the subject of much discussion before the grand reveal of the newest Apple Watch Series 7.
Other companies, such as Fitbit, can measure temperature, but only when sleeping and not in real-time. This post will go over smartwatches including a temperature sensor that can accurately measure body temperature.
This feature is unfortunately quite rare. None of the devices offering temperature analysis have an FDA-approved temperature sensor, which may appear strange as this application is less complex than detecting Atrial Fibrillation. There is little question that in the following years, such a feature will be as common as heart rate analysis, but it is currently a rarity in the world of smartwatches.
Best overall: Fitbit Sense
Fitbit’s flagship watch is the Sense for a reason. It has everything. The watch is a capable fitness watch with several health-related functions, including FDA-Cleared ECG, Heart Rate, Blood Oxygen Saturation, Heart Rate Variability, Stress, and Sleep Tracking, and, of course, Temperature tracking.
The only health-related measure currently unavailable is blood pressure, which we believe will be added soon. Fitbit is presently conducting clinical trials using its Photopletysmographic sensor and the Pulse Arrival Time logic.
Both the Fitbit Sense Sense and the Fitbit Versa allow you to enter core temperature data. This is essential since most smartwatches record skin temperature, which varies based on the outside environment. For example, consider going outside in the winter or summer. The temperature of your skin will vary greatly depending on the weather. That is why, in the cold, we wear gloves.
The Sense and Versa will continue to track your skin temperature if you add a reference point straight into the Fitbit App. Nonetheless, they will be able to connect the changes in skin temperature with those in core temperature using their algorithms.
This is particularly beneficial for detecting a fever during the ovulation phase. The average core temperature (temperature inside the body) ranges from 97°F to 99°F (36°C to 37°C); these modest temperature variations aid in predicting ovulation (the core temperature increases slightly during the ovulation.) We do not advocate using this approach just for contraception. There are many newborns in the world whose parents relied too much on the traditional “temperature technique.”
Expect to obtain an accurate temperature measured on the spot, as Fitbit smartwatches will only monitor your skin temperature when you sleep at night. The core temperature is at its lowest point of the day throughout the night, indicating a controlled environment that aids in the production of accurate findings. Day-to-day activities can also raise core temperature. One of the primary reasons for sweating when exercising is to reduce body temperature.
As a result, measuring temperature change is a reliable technique to identify physiological status for ovulation or health monitoring.

Best Temperature Fitness Tracker: Fitbit Charge 5
The Fitbit Charge 5 is our pick for the best fitness tracker in 2024. It has everything you’d expect from a monitoring gadget as well as many of Fitbit Sense’s health-related functions at a fraction of the price.
The Fitbit Charge 5 is still missing a couple of healthcare updates, including the long-awaited electrocardiogram (ECG app) and the Daily Readiness Score, which uses activity, heart rate variability, and sleep to calculate a score that tells you whether you should prioritize recovery over fitness daily.
The Fitbit Sense and Fitbit Charge 5 will monitor skin temperature changes at night but will not allow you to set a reference core temperature manually. This, in our perspective, is a disadvantage.
In any case, just the fluctuations are reported. Thus a change in skin temperature above might indicate either the ovulation period or a possible illness.
For less than $200, the Fitbit Charge 5 will monitor not only your exercise but also your health.

- For thorough sleep monitoring, a Fitbit Premium membership is required
Best for battery life: Amazfit GTS 2e
The Amazfit GTS 2e can measure skin temperature continuously and not only at night. This is a big plus when compared to the other products currently on the market.
The GTS features a form reminiscent of the Apple Watch Series.
The GTS 2e has a battery life of 14 days which is one of the longest for a smartwatch. It also comes with wifi transmission capabilities. Its twin brother, the Amazfit GTR 2e has the same core features but only synchronizes via Bluetooth. Amazfit claims that it offers up to 28 days of battery life which is truly exceptional but has been reported slightly exaggerated by most of the users.
As we mentioned, one of the key differentiation points of the Amazfit GTS 2e the temperature is monitored continually rather than only at night. This function is unique and enables more accurate detection of temperature fluctuations.
Thus, it will potentially ease the detection of an infection or the accurate monitoring of the ovulation period.

Best for Price: TicWatch GTH
The TicWatch GTH is a bit of an outlier. It resembles a clone of the Apple Watch even if the built quality, for one-quarter of the price, can not be compared of course.
When it comes to feature, the list is long and impressive. For less than $90, you will get a smartwatch with the ability to monitor skin temperature continuously, a 24 hours monitoring of the blood oxygen levels, and of course 24/7 heart rate monitoring and sleep tracking.
When we add the possibility to analyze 14 different sports activities, up to 10 days of battery life, and the remote control of your music. All of that in a fully waterproof (5 ATM) case, the TicWatch GTH is a serious watch to consider that will not break the bank.

- Continuous Temperature Monitoring
- Great price point
- Value for money
- No temperature
- Built quality could be better
To wrap up
It is now possible to purchase a smartwatch equipped with a temperature sensor that will not yet monitor the actual core temperature but will assist in detecting a potential illness or tracking the ovulation time.
None of these devices are FDA-approved, and they are unlikely to replace a regular digital infrared or buccal thermometer. Our favorite digital thermometer is the Kinsa Quick Scan, which costs only $20. Smartwatches should only be used for information. They have the potential to take one step closer to the ideal health wristwatch.
