Fitbit Sense review

The $329 Fitbit Sense is one of the most enthusiastic smartwatches yet. Yes, much more ambitious than the Apple Watch 6 or the Samsung Galaxy Watch 3. That's because the Sense has not simply an FDA-approved ECG sensor as well as blood oxygen analysis but the capacity to measure electrodermal tasks as well as skin temperature.


  • Display: 1.58 inches, 336x336 pixels
  • Water resistance: 50m
  • SpO2: Yes
  • Wireless: Wi-Fi, Bluetooth, NFC
  • Mobile settlements: Fitbit Pay
  • Size: 1.59 x 1.59 x 0.49 inches
  • Weight: 1.62 ounces w/ little band; 1.7 ounces w/ large band

The Apple Watch 6 does blood oxygen levels, too, yet Fitbit appears to be leading the advancement of smartwatches as they change from devices that simply track our actions to gadgets that take an even more holistic appearance at our health.

As I found during my Fitbit Sense review, these brand-new features are made not to offer you a sense of putting in jeopardy doom, yet rather a much better idea of exactly how you're doing. That's why the Fitbit Sense is just one of the most effective smartwatches and also best fitness trackers you can acquire. It additionally earned three separate acknowledgments in the 2021 Tom's Overview Honors for Health And Wellness.

Fitbit Sense review: Price and the release date

The Fitbit Sense is available currently for $329. You can acquire the watch with a black case and also a black band, or a gold case with a white band.

Those that haven't already subscribed or used Fitbit Premium will certainly also get a 6-month trial for Fitbit Premium ($ 9.99/ month, $79.99/ year), which includes advanced rest metrics, assisted programs, a health report, as well as video clip workouts. I'll share more on Fitbit Premium later in this review.

Fitbit Sense review: Design and also display

Fitbit Sense review

Made of stainless steel, the Senseis is tiny and also light, making it comfy to use both night and day. When positioned following the Fitbit Versa 2, the Sense is about the very same dimension yet has more rounded sides-- it's an extra round squircle. The best Side of the situation has a little touch-sensitive solid-state sensor that works as a button and triggers the watch to buzz a little when pressed. We clarify a lot more concerning the brand-new switch in our Fitbit Versa 3 review.

The Sense includes a silicone Infinity Band strap that I located a little bit picky to strap on my wrist. Fortunately, it's simple to switch out the bands.

I was actually pleased with Sense's AMOLED display. While not as high-resolution as the Apple Watch 6, it was brilliant, vivid, and crisp, as well as simple to check out also outdoors. The screen has 3 various illumination setups, and also you can either adjust the timeout or establish it to always-on (which reduces the battery life to about 2 days).

Fitbit Sense review: Health features

Contrasted to all the very best Fitbits, Apple Watch 6 as well as the Samsung Galaxy Watch 3, the Fitbit Sense is one of the most enthusiastic when it pertains to brand-new health features. The EDA and skin temperature sensor are distinct to Fitbit, and are suggested to offer you a better understanding of simply exactly how you're doing. It stays to be seen how valuable these metrics are, however Fitbit should have some credit rating for attempting something brand-new.

EDA sensor

I do not need a watch to inform me I'm worried. Yet, the Sense will certainly evaluate how worried you are, not simply based upon exactly how you feel after doom scrolling on Twitter, yet additionally your heart rate, rest, and also task levels. You can additionally take an EDA check, which measures your electrodermal activity, and after that factors in your other metrics. After, it asks you exactly how you're feeling, as well as provides you the choice of taking a guided meditation session to aid you relax.

Skin temperature

Comparable to its blood oxygen and also EDA sensor, the Sense's skin temperature level monitor is indicated to give a general sense of your overall health, but is not a main indicator of any kind of medical condition. Like the SpO2 sensor, you have to wear the Sense while you're resting for it to get an analysis; it takes three consecutive evenings for the watch to get a standard reading. A higher or reduced skin temperature level could suggest anything from the start of an illness or maternity, or something as easy as your room was warmer or cooler than the night before.

ECG sensor

Fitbit Sense review

The 3rd smartwatch to receive FDA authorization for its ECG app (the Apple Watch 6, as well as the Samsung Galaxy Watch 3, being the other 2), the Fitbit Sense can consider your heart beat to see if there's any type of irregular task or indicators of atrial fibrillation.

In order to make use of the ECG application, you need to go with numerous web pages acknowledging that just a physician can diagnose aFib, as well as that you're 22 years or older, don't have a pacemaker, and also comprehend that the assessment isn't a medical diagnosis.

After, you open up the ECG application on the Sense, area your thumb and forefinger at either edge, as well as wait 20 seconds. After, the application tells you if you have a regular or irregular heartbeat, or if the examination was inconclusive. It functioned rather well for me-- my ticker is simply great, according to the app.

SpO2 sensor

With the beginning of the unique coronavirus, blood oxygen tracking has actually gained a whole lot of focus as maybe a very early caution indication of Covid-19. Unlike the FDA-approved clinical tools that clip on completion of your finger and also beam light from one side to the various other (called a transmissive sensor), the Fitbit Sense, along with the Apple Watch 6 and also different Garmin watches, use what's referred to as a reflective sensor. While they additionally shine a light right into your skin, these sensors try to find representations that get better.

Partly since reflective sensors are less exact than transmissive sensors, the Sense, Apple Watch, and all various other wearables are not FDA-approved, so their analyses should be taken with a grain of salt. Actually, many Apple Watch reviewers have actually reported wildly-fluctuating readings.

The Sense verified pretty exactly in my tests. The exact same day it tape-recorded my blood oxygen degrees at 96 percent, I went to the doctor's workplace for a Covid test; as part of the test, my blood oxygen was determined at 98 percent. It's not a massive difference, however thinking about that a healthy and balanced blood oxygen reading is 95 percent and greater, there's little area for mistake.

Unlike the Apple Watch and various Garmin devices, the Fitbit Sense doesn't let you execute a test of your blood oxygen saturation. Rather, it takes an analysis while you're resting. It's most likely better by doing this, so you're not frequently checking.

Originally, you needed to make use of a particular Spo2 watch face while you were oversleeping order to get this reading, however, an upgrade to the Sense's firmware now lets you use any kind of watch face you desire. Fitbit says it will certainly include 7 brand-new watchfaces with SpO2 data by the end of the year.

Fitbit Sense review: Fitness features

Fitbit Sense review

Obviously, with GPS and a heart rate screen, the Fitbit Sense is indicated for fitness, also. I took the Sense on a few runs around my neighborhood; on the initial run, it took the Sense's GPS concerning a min to obtain a signal; on subsequent runs, it secured on in regarding 30 secs, staying up to date with the very best running watches around.

Throughout the run, the Sense's GPS and heart rate monitor were accurate and quick, and also it was very easy to read even when on the step. The Sense has a lot of various other details, consisting of the capability to tailor what's on the screen as you're running, establishing the screen to Always-on while you're working out, Auto-pause, as well as Run Detect.

The watch can additionally track biking, Bootcamp, circuit training, elliptical machine, golf, treking, interval workouts, kickboxing, fighting styles, Pilates, spin, swim, tennis, treadmill, yoga exercise, as well as more.

Fitbit Sense review: Sleep tracking

The very first couple of nights I used the Sense, its sleep tracking proved erratic, occasionally logging that I really did not drop off to sleep till 2:30 in the morning, and various other evenings breaking up my rest into two parts. You're able to modify your rest logs after the reality, but if you do that, you don't get a sleep rating. I after that changed the sensitivity to Sensitive from Regular, as well as one evening, Sense was able to accurately tape-record my zzzs. The 2nd evening-- a bad rest evening for me-- the Sense believed I slept for simply 2 hours.I think I got extra, but I was pretty worn out.

When it works, you obtain a general sleep rating-- a number more detailed to 100 is much better-- as well as a check out your heart price and estimated oxygen variant. Fitbit's application additionally shows the quantity of time you spent in light, deep, and also rapid eye movement rest.

Fitbit Sense review: Fitbit Premium

If you sign up for Fitbit Premium ($$ 9.99/ month, or $79.99 annually), you get a few extra features, a lot of which are deeper dives right into specific measurements.

A Health Metrics dashboard will certainly let you see your 7-day and also the 30-day background for heart price irregularity, breathing rate, oxygen saturation (SpO2), and skin temperature variation. Offered the importance of a few of these features, Fitbit claimed it was taking a look at a means to bring even more of them to non-Premium members.

Other than that, Fitbit Premium clients get accessibility to a number of video clip workouts they can watch on their mobile gadgets, which are as brief as 3 mins and also as lengthy as half an hour that cover all components of your body. Examples consist of "10-minute Glutes with Katie," "3-minute Leg Obstacle," as well as "15-Minute HIIT with Lisa." There are also a number of food preparation videos.

There are also 16 assisted programs, that include every little thing from encouraging better resting as well as eating routines to running and weight training.

Fitbit Sense review: Smartwatch features

Fitbit Sense review

While not as durable a smartwatch as the Apple Watch 6 or the Samsung Galaxy Watch Active 3, the Sense covers the essentials, plus a bit more.

If you're searching for a smartwatch that will allow you check your bank equilibriums, control all your wise home gadgets and make phone telephone calls untethered, this isn't it. Fitbit's smartwatch application shop is nowhere close to as large as Apple's, yet there are third-party apps for Starbucks, Uber, Yelp, Walgreens, United Airlines, Strava, The New York Times, and a couple of others. You will not locate MapMyRun on the Sense, as Fitbit probably likes you utilize its run-tracking.

The Fitbit Sense can save playlists from Deezer and Spotify, so you can play songs right from the watch. While you can control Spotify from the watch, you can't download songs from that solution to the watch itself. Considering Spotify is just one of the biggest music services, I hope this modifications soon.

Like the Versa 2 and also Versa 3, the Fitbit Sense has Alexa integrated in, so you can summon Amazon's voice assistant from your wrist. And also, due to the fact that Fitbit was gotten by Google, Google Aide is likewise offered. However, you can just have one assistant energetic each time. If you're using Alexa, it will certainly respond to you through the Sense's integrated speaker

You can also address calls using the Sense when your phone is neighboring as well as, if the Sense is attached to an Android phone, you can also react to message messages using voice-to-text.

And, the Sense has Fitbit Pay, which can be utilized at virtually the exact same places as Apple Pay.

Fitbit Sense review: Battery life

Contrasted to the Apple Watch Series 6 and also Samsung Galaxy Watch, Fitbit Sense's asserted 6-day battery life is absolutely epic. (If you're making use of GPS proactively, the battery life is concerning 12 hrs). Thinking about the watch is indicated to be used all day and evening, it helps that you do not have to bear in mind to charge it daily.

After 4 days of using the watch day and night, plus one 30-minute run making use of GPS, my Sense watch was down to 19 percent, which is exceptional and about in line with Fitbit's cases. A half-hour run utilizing a general practitioner knocked the battery down by four percent.

The Sense comes with a proprietary magnetic USB charger, which snaps securely to the rear of the watch; mine went from 19 percent to completely bill in less than an hour.

Fitbit Sense review: Judgment

I get a lot of pitches for gadgets declaring to supply much better rest, health, and fitness, and also much of them seem like modern snake oil. For every condition, there appears to be a tech-based solution. And, despite having the extra trusted business, some features blur the line between a government-approved medical tool and one that's not.

That's why I such as the Fitbit Sense's technique to things such as its SpO2 and also skin temperature level sensors. By not permitting you to proactively examine your blood oxygen levels, it makes it much less likely that somebody will certainly utilize the Sense instead of an FDA-certified gadget to see to it you're healthy and balanced. Rather, it uses these readings, in addition to a handful of others, to offer you a much more rounded view of your body. While the Apple Watch 6 is still the best general smartwatch, the Fitbit Sense provides the most of any smartwatch when it comes to your health.
