Fitbit Sense 2: the most powerful of the range
The Fitbit Sense 2 is lighter (by 15%) and thinner (by 10%) than the Fitbit Sense. The strap anchors have been renewed to make it more comfortable to wear and the center of gravity has been moved lower to make it more ergonomic. Beyond that, and the button, which once again makes an appearance, the differences from the previous model are on the inside.
The device is equipped with the latest version of Fitbit Os, which features a new tile-based design. Fitbit, furthermore, claims that its fluidity of it has been improved. The watch features heart rate analysis, electrocardiogram, activity level, SpO2, automatic sports detection, sleep analysis, and stress tracking.
Stress is undoubtedly one of the points that Fitbit has placed the most emphasis on with Sense 2. The company has implemented a continuous electrodermal activity analysis (cEDA) sensor that analyzes the body’s response throughout the day to help us manage those peaks.
This sensor uses heart rate, heart rate variability, and skin temperature to help us, according to Fitbit, to “detect stressful situations in advance”. The watch will then make personalized suggestions for managing stress and guide us in creating a routine.
Sleep has also been improved, adding an option called “Sleep Profile”. Using this feature, the device analyzes the past month’s sleep patterns to detect trends. Our “trend” is represented by a “bio-animal” that gives us information about how we sleep and how they change over time. It is, of course, a premium (paid) feature.
The watch additionally supports Alexa and supports Bluetooth calls, as well as notifications that can be answered. It is appreciated that Google is getting its hands on its OS, as Google Wallet (to pay without going through Fitbit Pay) and Google Maps with turn-by-turn alerts are also coming soon.
It also has an integrated GPS chip, vibration engine, and battery capacity not determined, but with which Fitbit promises up to six days of autonomy. In addition, the company has implemented a fast charging system that allows you to get a day of autonomy in 12 minutes.
Fitbit Versa 4: now lighter and thinner
As for the Fitbit Versa 4, the device is also thinner and lighter than the previous model and recovers the side touch button, something designed to be used with wet hands. The main difference between this and Sense 2 is that Versa 4 does not have the cEDA sensor, ECG, or advanced stress monitoring tools.
From Fitbit, they point out that the Versa 4 has 40 exercise modes, with some new ones like strength and dance workouts, and of course, it has an integrated GPS chip. The device also features SpO2 monitoring, heart rate, heart rate variability, blood glucose index, menstrual health monitoring, sleep, and stress.
Similarly, the watch is capable of receiving calls via Bluetooth, answering notifications, and invoking Alexa. Soon, it will also receive support for Google Maps and Google Wallet. The battery promises the same: six days of autonomy with fast charging.
Pricing and Availability of the Fitbit Sense 2 and Versa 4
Both the Fitbit Sense 2 and the Fitbit Versa 4 are available for pre-order now on Fitbit’s website. The Fitbit Sense 2 costs $299.95, while the Versa 4 remains at $229.95. The devices will ship on September 29.
