Frequently ranked among the best smartwatches you can buy, Fitbit’s flagship devices boast detailed fitness tracking, reliable sleep monitoring, and the company’s exemplary companion app. While the  Versa 4 and Sense 2 still have a lot in common, their differences are worth sorting through to find out which is the right fit for you. Read more in our Fitbit Sense 2 vs Versa 4 comparison.

Design

We were already fans of the Versa 3 and original Sense and this year both lineups sport significant design improvements. Most prominently, each adds a much-appreciated physical button. This is a major upgrade in terms of usability, considering how finicky we found the inductive button on the previous models. In addition to being clickable, the buttons are also relocated slightly up the body of the watch for smoother interaction.

Beyond the button, both the Sense 2 and Versa 4 are thinner and lighter than their predecessors, with lower centers of gravity. Fitbit suggests this redesign will aid users’ comfort during all-day wear, as well as when sleeping with the devices. At a glance, they continue to look almost identical.

Among the most notable design features added to this generation is a physical button now featured on both models.

For getting the most out of the devices while they’re on your wrist, both models also received internal overhauls. New hardware and an upgraded processor translate to faster load times and snappier interactions. Meanwhile, a refreshed operating system with customizable tiles means more personalized organization and easier access to the information users want front and center. On the updated Fitbit OS, you can quickly swap between fitness stats, workout modes, and more.

Deviating from the Versa 4, the Fitbit Sense 2 showcases an upgraded way to collect EDA and ECG readings. Instead of a metal strip running along the edge of the device like in the original Sense, metal is now integrated into the glass face of the watch. This metal interface provides a more refined look and easier interaction between users and the device.

Features

The easiest way to wrap your head around the Sense 2 vs the Versa 4 is to consider the latter a pared-down version of the former. All features found on the Versa 4 are also available on the Sense 2. Meanwhile, many of the advanced health-tracking sensors and tools are only available on the Sense 2.

Both smartwatches still pack large AMOLED screens, speakers with Bluetooth call and Alexa support (no Google Assistant), and a refreshed OS. Both track your activity and heart rate and offer familiar features such as run/walk detection and built-in GPS.

For fitness tracking enthusiasts, Fitbit now pushes more than 40 exercise modes including everything from dancing to HIIT to CrossFit. Fitbit Premium users can also tap into their Daily Readiness Score for workout and recovery guidance and a personalized Active Zone Minutes goal.

Consider the Versa 4 a pared down version of the Sense 2, cutting advanced health sensors for a lower price tag.

For deeper insight into your overnight stats, both the Versa 4 and Sense 2 spotlight Fitbit’s Sleep Profile. Analyzing your key sleep metrics against those typical for your age and gender, Fitbit will generate your monthly sleep profile. This includes an adorable animal phenotype, plus personalized guidance on how to improve your sleep quality. This tool is only accessible with a Fitbit Premium subscription, but luckily both smartwatches come with a free six-month subscription at purchase.

The most exciting feature to hit both models is support for Google Maps and Google Wallet. Though not available at launch, these two Google favorites will be available on Fitbit smartwatches by the end of the year. That means access to turn-by-turn directions on your wrist and the convenience of digital payments everywhere Google Pay is accepted.

The devices also share specs in terms of battery life and charging. Fitbit claims both lineups can last more than six days on a single charge, mirroring the claims of the original Sense and Versa 3. When you do need to top off, either device is able to grab a full day’s worth of battery in 12 minutes.

Similarities in the devices’ feature sets stop short at advanced health sensors. Fitbit’s original Sense stood out as a powerful health monitoring tool. The latest generation is even more involved than ever.

Headlining the device is a continuous Body Response sensor for all-day stress management. Using your heart rate, heart variability, skin temperature, and continuous, all-day EDA metrics, the Sense 2 can help identify stress triggers and alert users to changes in their bodies. It also offers a Check-in button where you will find mindfulness tools like guided breathing and more.

This feature is in addition to the device’s electrocardiogram (ECG) app, where users can take on-demand AFib assessments to keep tabs on signs of the condition. Both the Sense 2’s EDA sensor and ECG boast FDA clearance. Neither is available on the Versa 4.

The Versa 4 launched at $229 and the Sense 2 at $299. That’s a $70 upcharge for detailed health monitoring that may or may not be necessary for you personally. Both prices also include half a year of free access to Fitbit Premium. This allows users test out features otherwise hidden beyond a paywall. Overall, the pricing is competitive compared to the latest devices from Samsung and Apple, keeping Fitbit squarely in the smartwatch conversation.

The two devices do distinguish themselves from each other in color options. The Versa 4 is available in graphite with a black band, platinum with a band in Aegean Blue, or Copper Rose with a band in either Rosewater or Beet. The Sense 2 is available in graphite with a graphite band, platinum with a lunar white band, or pale gold with a band in Blue Mist.

Fitbit Sense 2 vs Fitbit Versa 4: Which should you buy?

As we saw in the last generation of these devices, Fitbit’s top smartwatches exhibit a lot of common features.Likewise, the Sense 2 and Versa 4 still share similar design aesthetics as well as many internal specs. Only advanced health-tracking tools set the Sense 2 apart.

For most people, the Versa 4 brings enough to the table. With its physical button, added sport modes, and future support for Google’s top apps, the Versa 4 is a nice wearable. Add in six free months of Fitbit Premium and it’s a great upgrade or first entry into the Fitbit ecosystem.

However, if you’re deep into health tracking or have any health concerns, the Sense 2 might be worth the extra cash. As mentioned, the Sense 2 offers ECG, EDA, and cEDA readings. These tools can help users gain a more holistic understanding of their wellness. Fitbit’s Body Response feature is also only available on the Sense 2. In short, the Sense 2 is the best health-focused device available from one of the most reliable names in tracking.

If you want the absolute best features and tools Fitbit has to offer, the Sense 2 is the pick.

Deciding between the Sense 2 vs the Versa 4 comes down to your specific needs. If your goal is to track your fitness basics, the Versa 4 offers great value at a good price. The Sense 2 is only the right pick if you want the best health monitoring Fitbit has to offer.

All that being said, we are also quite partial to the older models. The latest Fitbit smartwatches drop a number of key features we feel made the lines well-rounded. The Versa 3 and the original Sense offer third-party app support, and Wi-Fi connectivity. They also support multiple Google Assistant and onboard music storage. The newest generation of both lines do not offer any of these features.

What if no Fitbit device is right for you? If you’re an iPhone user, we still suggest the Apple Watch Series 8 for the best smartwatch experience available. For the top Wear OS device you can buy, we direct shoppers to the recently released Samsung Galaxy Watch 5 Pro. There are also plenty of options from Garmin worth considering.
