  • A bit pricey
  • Audio quality for calls isn’t great

When I think of fitness trackers, I immediately think of Fitbit. This is a brand that has become synonymous with step counting and general fitness statistics gathering, but Fitbit makes devices that are more than mere data harvesters. The Fitbit Sense 2 is a full-blown smartwatch, offering many of the features you look for in a wrist-mounted smart device. Given Fitbit’s established prowess at building great fitness tracking devices, it’s safe to assume that the Sense 2 will perform well in that regard, but can it also be a great smartwatch at the same time?

Fitbit Sense 2 design and comfort

The Sense 2 has a distinctly high-end look and feel. It’s a visibly classy smartwatch, particularly with the optional Brother Velles leather band. I tested the soft gold aluminum-colored Sense 2, but it’s also available in platinum aluminum and graphite aluminum colors, alongside a wide array of optional band colors and materials.

I’m very sensitive to watches, and coming from the ultra-light and exceptionally comfortable Fitbit Inspire 3, I wasn’t looking forward to using a larger device on my wrist. However, I was pleasantly surprised to find that the Sense 2 is quite comfortable to wear. Both the infinity bands I tested and the Brother Velles leather band were great, and while I found the leather band to be slightly more comfortable, the infinity band that ships with the Sense 2 feels good, too, and I love the innovative clasp system.

The process of attaching and detaching watch bands is the best of any Fitbit system I’ve used. The locking mechanism is easy to detach, but also very secure. If you like to swap out bands for different scenarios and styles, the Sense 2 is ideal.

Fitbit Sense 2 setup process

While initial setup was a breeze, getting all the features of the Sense 2 up and running took a bit of work. You have to go through and grant a lot of permissions before the watch will be fully functional. While it was kind of a headache to diagnose why certain things weren’t working and dig through the app to activate them properly, I do appreciate that this process enables a greater degree of user knowledge of data collection by the Sense 2.

Fitbit Sense 2 battery life

The Fitbit Sense 2 is rated to last over six days on a single charge, and based on my time wearing the device, I believe this figure to be accurate. It’s roughly what you’d expect from the original Fitbit Sense, though keep in mind that it will vary based on how you use the device. It’s not quite up there with the incredible battery life of the Inspire 3, but it’s more than acceptable, considering how much more powerful the Sense 2 is than the Inspire 3. Just 12 minutes of fast charging will get you an entire 24 hours’ worth of juice.

The Sense 2 features a really gorgeous display, with deep blacks and vibrant colors, and is bright enough to use in harsh daylight conditions. It’s easy to read at a glance, and the numerous available watch faces look great.

Touchscreen responsiveness in the Sense 2 is extremely good, without any noticeable lag or touch recognition issues. Navigating menus is slick and intuitive, as is the operation of the newly redesigned physical button. Motion detection to wake up the display also works reliably.

Call audio is functional, but not great compared to the speakers and microphone on my Samsung Galaxy S22 Ultra, or my Samsung Galaxy Buds 2. I found that I had to hold the watch close to my face to maintain reasonable microphone quality, and the output from the built-in speaker is rather crackly. It’s there if you need it though, and it’s a nice feature to have.

In terms of durability and water resistance, the Sense 2 is remarkably tough. It’s water resistant down to 164 feet underwater and is rated to operate between -14 and 113 degrees Fahrenheit. I wore the Sense 2 on a particularly rugged off-trail route — finding adventure, exploring, and documenting a remote ancient forest. This involved descending and ascending cliffs, crawling through thickets of devil’s club, and a dunk in a waterfall. The watch came through without a scratch.

The many fitness sensors of the Sense 2 performed admirably. My impression is that this watch is even more accurate than the Inspire 3, which I praised for the accuracy of its sensors. This device harvests an impressive amount of data to help monitor your health with.

Like other Fitbit devices, the Sense 2 tracks your steps and heart rate, but its sensor array goes much farther than that. The Sense 2 includes a unique Body Response sensor designed to detect and manage stress. This sensor tracks ElectroDermal activity, heart rate, heart rate variability, and skin temperature. By using this data, the Sense 2 is meant to help you be more aware of what causes you stress and thereby reduce it over time.

The Sense 2 can also help detect atrial fibrillation using an electrocardiogram app, and is even capable of measuring blood oxygen levels. While none of this is intended for serious medical use, the wide range of sensors, combined with powerful analytic software, enables the Sense 2 to be a valuable companion for keeping track of both your fitness and overall health. The more you engage with it, such as logging your food and water consumption and participation in various activities, the more effective it is.

A number of features weren’t available at the time of testing, such as Google Maps and Google Pay integration. Fitbit Pay and Amazon Alexa are already available, as is the ability to see and respond to notifications from your phone. It needs to be noted that the ability to respond to notifications and texts is only available on Android.

Fitbit Sense 2 app and premium subscription

The Fitbit app is an essential companion to the Sense 2, and it’s great both for adjusting settings and permissions, as well as monitoring the many stats harvested from the watch. A Fitbit Premium subscription ($10 per month, or $80 per year) gets you access to a host of extra features, including a daily readiness score, sleep profile, and wellness report, among many other advantages. The Sense 2 includes a six-month Fitbit Premium subscription.

Fitbit Sense 2 price and availability

Available now at $300, the Sense 2 isn’t cheap, but its design and extensive feature set justify that cost. If you’re looking for a less expensive fitness tracker, the Fitbit Inspire 3 is a fantastic option at a third of the price of the Sense 2, albeit at the cost of many of the bells and whistles found in the Sense 2.

Both a feature-rich fitness tracker and a compelling smartwatch

The Fitbit Sense 2 is packed to bursting with useful features, all wrapped up in a beautiful and comfortable package. The ability to track a wide variety of metrics gathered from its myriad sensors, all processed into understandable information by its advanced software is highly compelling. If you’re looking for the best fitness and health-focused smartwatch, this is the one to buy.

Fitbit Luxe gets major updates with SpO2 measurement and always-on display
The Fitbit Luxe tracker has received major updates Credits: Fitbit official.

 The Fitbit Luxe launched in July 2021 and was reviewed by our smart home editor, John Velasco, as a beautifully designed and modestly sized fitness tracker. It has now received two major updates bringing new features to the table. 
Version 1.151.16 has added SpO2 measurements that allow users to track their blood oxygen saturation levels when asleep. SpO2 tracking is currently available in devices such as the Fitbit Charge 4, Charge 5, Fitbit Versa 2, and the Fitbit Versa 3, so it's nice to see it roll out to other devices in Fitbit's lineup.  To use the function, check the SpO2 tile on the watch face or the Health metrics tab on the mobile app. Additionally, Fitbit has published a detailed manual on tracking Sp02 levels with this model.
The second major update enables always-on-display functionality. As the name suggests, users no longer need to wake up their Luxe trackers to check the time or their workout tracking data. To use the feature, it's essential to enable the updated display functionality in Settings. You'll be warned that the feature can increase battery drain, so keep that in mind if runtime is important to you. 
The new Fitbit Luxe Fitbit
Apart from these two updates, there are several smaller ones. A bigger font size has been added to the trackers' screen, along with a series of bug fixes and patches. These updates are being rolled out on an incremental basis and may take some time to reach particular regions. To check if an update is available for the device, you should be able to see a pink banner when you log into the Fitbit App, and you'll be notified of further updates once they're available.

Fitbit Charge 5 adds sweat-based stress sensor, rounded design
Fitbit Charge 5

Following a high-profile leak that spilled most of the beans, Google-owned Fitbit today announced the Charge 5, an upcoming addition to the company's lineup of fitness trackers. On the outside, the Charge 5 borrows heavily from the Fitbit Luxe, with a sleek, rounded, colorful display. Under the hood, though, is where you can find all the goodness.
Vibrant always-on display
The most noticeable change in the Charge 5 is the always-on display that lets you check your health stats instantly and curves to fit the wristband. The always-on feature can be turned off to help you eke more battery life from the device. If you want to wake the display, all you need to do is raise your wrist.

Built-in GPS
Similar to the Charge 4, the new Charge 5 will ship with built-in GPS to track your outdoor activities. Not only will you be able to view your activity on a map, but the Charge 5 will also display your workout intensity along the GPS track. You'll be able to see at a glance where you were pushing yourself to your limit and where you were taking it easy.
New stress-monitoring sensor
The Charge 5 joins the Fitbit Sense as Fitbit's first trackers to feature an EDA sensor, which measures your sweat to monitor your stress levels. The sensor is used to generate a Stress Management Score to help you manage your daily stress levels.
Daily Readiness
Daily Readiness is a new metric added to Fitbit's Premium service. Like Garmin's body battery, the Daily Readiness Score takes heart rate variability, sleep, and activity into account to calculate your overall energy level. This new metric determines whether you are ready for a crushing workout or an extra-long nap. Daily Readiness helps athletes manage their exercise and recovery schedule so they can get the most out of their activities.
