Fitbit Sense 2 and Fitbit Versa 4 are identical fitness trackers in terms of design and screen size, but they also share a few differences.
The Sense 2 offers advanced features such as ECG monitoring, skin temperature tracking, and stress tracking. Apart from these, both trackers are so similar that you can barely spot the difference.
We’ll take a quick ride with both of these fitness trackers to help you decide which one fits your budget and needs.

Price
The Fitbit Sense 2 comes with a price tag of $249 and is available in Shadow Grey/Graphite Aluminium, Lunar White / Platinum Aluminium, and Blue Mist / Soft Gold Aluminium.
The Fitbit Versa 4, on the other hand, costs $50 less compared to the Sense 2, or $199. It comes in Black / Graphite Aluminum, Waterfall Blue / Platinum Aluminum, Pink Sand / Copper Rose Aluminum, and Beet Juice / Copper Rose Aluminum.
Design and Display
Both fitness trackers have the same square shape and round edges, surrounded by an aluminium casing and Corning Gorilla Glass 3, protecting the screen from scratches.
The Sense 2 boasts an 1.4-inch, 317 PPI, 336 x 336 pixels AMOLED display, while the Versa 4 boasts an 1.58-inch, 268.5 PPI, 336 x 336 pixels AMOLED display. Although they offer the same screen size, the higher pixel density of the Sense 2 can give you more clarity and a crisper experience.
Both trackers offer silicone bands, but the Sense 2 comes in Shadow Grey, Lunar White, and Soft Gold, while the Versa 4 comes in Graphite, Platinum, and Copper Rose colorways.
Both have a haptic button on the side for tasks like turning on the watch screen, opening the app menu, activating Alexa, and much more. Plus, both fitness trackers have a water resistance of 50 metres, so you can use them for swimming.
Health and Fitness Tracking
When it comes to health and fitness tracking, both can perform basic tasks such as heart rate tracking, SpO2 monitoring, stress monitoring, and women’s health tracking, but only the Sense 2 offers an ECG reading that can detect irregular heart rhythms, which could be a sign of atrial fibrillation (AFib), and real-time stress tracking via a cEDA sensor.
Both can monitor skin temperature, but the Sense 2 features an actual skin temperature sensor that can help you detect changes in your overall well-being. Both offer wellness reports (requires a Fitbit subscription), which provide a pdf of all your health and fitness data that you can share with your health care professionals.
Both can track sleep in multiple stages (including deep, light, and REM) and decide when you fall asleep using your body movement and heart rate patterns. Plus, it also provides a sleep score ranging from 0 to 100, which can help you get an insight into your overall sleep quality.
They can also perform other basic features such as step tracking, calories burned, and distance travelled.
In terms of sports tracking, both can track multiple sports, and they can automatically detect up to six sports modes, including Walking, Running, Biking, Swimming, Elliptical, Sports, Aerobic workouts. Plus, they offer a daily readiness score, which tracks whether your body has recovered from previous training sessions or not.
Additionally, both have built-in GPS, meaning you don’t need your smartphone for GPS tracking, but the Fitbit Sense 2 connects faster compared to the Fitbit Versa 4, which can be quite frustrating to deal with and also impacts the fitness data.
Smartwatch Features
In terms of smartwatch features, they both lack in this section and fall behind compared to other smartwatches on the market. Neither of these trackers supports third-party apps, or allows for music storage or playback. The only major feature they offer is the ability to perform contactless payments via Fitbit Pay.
Plus, neither of these devices supports Bluetooth calling; it only allows for notifications from emails, calls, and text messaging, which you get on most of the smartwatches available on the market right now.
Although Fitbit is owned by Google, these devices don’t even have a Google assistant, they only offer Amazon Alexa, which works when you sync to your phone via Bluetooth.
Battery Life
If we talk about battery life, both the Fitbit Sense 2 and the Fitbit Versa 4 last for around six days on a single charge. Even with the GPS tracking, these trackers can last for days, which is good compared to Apple Watches, which need frequent charging.
In terms of charging, both need 1–2 hours of charging to fully charge the device, but if you are in a hurry, only the 12 minutes of charging can give the watch enough juice to survive for a day.
Remember, battery life depends on individual usage, which can last more or less depending on the features you are using. Plus, features like GPS tracking and an always-on display drain more battery life.
Which should you choose?
Which should you choose between the Fitbit Sense 2 and Fitbit Versa 4? It depends on your personal preference and the features you want in your fitness tracker.
If you are on a budget, then you have to sacrifice some features such as ECG, real-time stress tracking, and slower GPS connectivity, which can ruin your overall watch experience.
So I personally choose to spend an extra $50 to get advanced health features, which I mentioned above, plus bright and colourful displays. Apart from these, they are both identical, so if you don’t want the above-mentioned features, you can go for the Fitbit Versa 4, which can also perform most of the features.
So it’s totally up to you now to decide which feature is your top priority and go for the one that fits your budget and style preferences.
