Fitbit recently renewed its catalogue of wearables with the Fitbit Versa 3 and Sense, two models of smartwatches that are currently ranked as the most advanced of the same, since the first has been presented as the successor version of the Versa 2, which until little was the flagship watch of the brand, while the second comes as the first in a series that is superimposed on the Versa, for being of better performance. Given the above, we compare these two smartwatches, to determine how much difference there is between them and give a verdict on which is the best for you, based on your budget.

Although there are several differences at the level of internal characteristics and functions in both and which we will highlight in detail below and through their respective technical sheets, what is curious is that they are practically identical, as far as appearance is concerned. Here the company has not wanted to bet on different designs, something that does not fall badly, but it would have been more interesting if that were the case, although this is something that is typical of personal taste.

We are facing two smartwatches that maintain the same line that we find in the Versa 2, so we find square screen formats, but with slightly smoother and rounded corners and finishes, which is why both the Versa 3 like the Sense, present a more premium hand and wrist feel, something that can also be seen with the naked eye.

In terms of screens, there are no big differences in the panels of one and the other. Both boast an AMOLED technology screen that has a 1.58-inch diagonal and produces a resolution of 336 x 336 pixels. Of course, it is tactile and full color, in addition to being protected by a resistant glass (Corning Gorilla Glass 3, in the case of the Fitbit Sense. They also present a high image quality, although their pixel density per inch is not defined. (dpi), and excellent brightness that can be adjusted automatically thanks to the ambient light sensor, and there is no need for the Always-on Display function.

Regarding activity and sports tracking, the Fitbit Sense has more to offer, as it has a heart rate monitor that comes with the ECG function, which is not yet enabled due to awaiting clearance from the FDA and others. The Fitbit Versa 3 only makes use of a heart rate monitor which, although advanced and very accurate, does not offer ECG functions since we are only talking about a heart rate monitor in this case.

On the other hand, Fitbit Sense also makes use of an EDA sensor, which is capable of measuring stress through the reading of factors such as skin moisture (sweating), heart rate variability (HRV) and body temperature, among others. This advanced monitor is not available on the Versa 3, but one that is also capable of collecting stress metrics is.

Something that both smartwatches do share is asleep quality monitor, body temperature sensor (helps stop fever), 3-axis accelerometer, altimeter, relative SpO2 sensor for measuring oxygen saturation in the blood and a gyroscope, sensors that are available to obtain various metrics such as calories consumed, distance travelled and steps are taken. There is also a female function that includes tracking the menstrual cycle.

When we talk about connectivity, both boast of having an integrated GPS module that relies on GLONASS, Bluetooth 5.0 connectivity, Wi-Fi 802.11 b / g / n and an NFC chip for making contactless payments to Through the brand’s Fitbit Pay payment system, which is already widespread in several countries, but not around the world, as a fact to take into account.

Both are compatible with smartphones with Android and iOS operating system. In turn, they come with a water resistance of 5 ATM (50 meters), they are built-in plastic and aluminium alloy, and the straps that come by default are silicone. Other features include music control and a pre-installed Spotify app (Fitbit Sense only).

The manufacturer did not define the battery capacity of these two smartwatches but did reveal that they promise an autonomy of up to 6 days, which surely is not many hours if the GPS is activated and running. Something very good is that they have support for fast charging technology.

The Fitbit Versa 3 comes with the voice assistant Google Assistant, at the same time in which the Fitbit Sense integrates, in addition to the aforementioned, Amazon from AlexaM; here you can choose between one and the other. In the end, the first model will also feature the latter, but later through a software update. This is thanks to the fact that they both implement a microphone and speaker.

To begin with, we are looking at two smartwatches that are aesthetically identical, which is why in this section we do not find a superior selling point of one over the other. We aim the same on the subject of screens, because the panels they boast about are the same.

However, when we touch the sensors section, we see that the Fitbit Sense, having an ECG monitor and a more advanced stress monitor, is superior. In turn, the fact that it offers two smart assistants and a Spotify app also makes it a more interesting option.

On the other hand, the price is something that must be taken into account to determine if the Fitbit Sense is actually a better purchase option. And there is no doubt that it is, but perhaps not for everyone. Here you must ask yourself if you have enough money to buy it and, if so, if you really need everything that it offers more because, if you do not, the Versa 3 is your option to choose. All things considered, this latest model is just as good and only slightly inferior.
