If you’re thinking about getting a Fitbit, the Sense 2 and Versa 4 are two of the brand’s most popular smartwatches. Both the smart watches share a lot in common, but they’re built for slightly different users. Let’s dive into what sets them apart so you can figure out which one is best for you.
Fitbit Sense 2 vs Versa 4: Our Verdict
If you want the best health insights and stress management features, go for the Fitbit Sense 2. It’s the better choice for those who want more than just basic fitness tracking and like the idea of ECG monitoring.
But if you’re after a reliable, budget-friendly Fitbit that handles fitness tracking and smart notifications with ease, the Versa 4 delivers excellent value without the extra bells and whistles.
Both are comfortable to wear, look stylish, and offer good battery life, so you can’t really go wrong. It just depends on how deep you want to go with your health data.
Fitbit Sense 2: Quick Overview

This is Fitbit’s premium health-focused smartwatch. It adds advanced features like an ECG app to monitor heart rhythm and an EDA sensor for stress tracking. The Sense 2 has a sleek design with metal accents and offers a rich set of fitness, sleep, and wellness tracking tools. It’s great if you want a deeper look into your health and don’t mind spending a bit more.
Fitbit Versa 4: Quick Overview

The Fitbit Versa 4 is a good choice and it covers all the basics well which includes heart rate monitoring, sleep sleep tracking, various exercise modes, built-in GPS, and smartphone notifications. It’s lighter on the advanced health sensors, which keeps it more affordable. If you want a reliable smartwatch for everyday fitness and smart features without extras, then Fitbit Versa 4 is a good choice.

What Makes FITBIT Sense 2 Stand Out?
The Sense 2 steps up with two health features that the Versa 4 doesn’t have:
- ECG app: It can record a quick electrocardiogram to check for irregular heart rhythms like atrial fibrillation. This feature is medically cleared in many countries, so it’s not just a gimmick.
- EDA sensor: This tracks tiny changes in your skin that relate to stress levels. You can do quick stress scans and get guided breathing exercises to help you chill out.
If you want more than basic fitness tracking and care about detailed heart health insights, then we recommend buying the Sense 2 instead of Versa 4.
Fitbit Sense 2 vs Versa 4: Design and Comfort
Both watches look clean and modern, with lightweight designs that don’t feel bulky on your wrist. They’re about the same size, around 40mm, so whether you’re into fitness or just want a smart watch that’s comfortable to wear all day, then either one works.
One thing to note is the physical button on the left side on both the models, which some lefties might find a bit awkward since you can’t switch the screen orientation. Both the watches have good water resistance, so swimming and showering are no problem. But Fitbit advises against using it in hot tubs or water sports that involve a lot of splashing or pressure.
The Fitbit Sense 2 feels a little more premium with its metal-infused edges and an option for a gold-tone finish, while the Versa 4 goes for a simpler aluminum case with a nice rose gold color choice.
Screen and Battery: Fitbit Sense 2 vs Versa 4
Both watches have bright AMOLED screens that look great indoors and outside. You can keep the screen always on if you want, but be prepared for your battery to drain faster if you do.
Speaking of battery, you’re looking at around six days on a full charge with typical use. Charging is quick, a 12-minute charge can give you hours of use, which is super handy if you forget to charge overnight.
Tracking Your Health and Fitness
If you’re mainly after fitness tracking, then again both watches are a good choice. Both cover everything from heart rate monitoring and step counting to sleep tracking and built-in GPS, so you don’t need your phone for runs or bike rides.
You also get over 40 exercise modes, like running, swimming, yoga, and more, plus reminders to move when you’ve been sitting too long.
And if you like the idea of contactless payments, both support Google Wallet.
Smart Features OF FITBIT VERSA 4 and sense 2
You’ll get notifications for calls, texts, and calendar events on both watches. Android users can send quick replies right from the watch, but iPhone users can only view notifications.
Alexa is the only voice assistant on these watches, no Google Assistant yet. Audio controls let you play, pause, or skip tracks, but neither watch lets you store tracks offline, so your phone has to be nearby.
Some Things to Keep in Mind
Neither watch supports Google Assistant, so if that’s important to you, these might not be the right pick. Also, you won’t get offline audio storage or third-party apps on either model.
Swim tracking is basic, you won’t get lap counting or swim coaching features. And while the heart rate monitors are pretty good, they might not be perfect during very intense workouts.
Which One Should You Pick?
If advanced health tracking is a priority and you don’t mind paying a bit more, the Sense 2 offers those extra sensors and a slightly more refined look.
If you want a good, budget-friendly Fitbit with all the core features you need for daily fitness and notifications, the Versa 4 does the job well without the extras.
