AI-generated from the text of customer reviews
Customers are mixed about the performance of the wearable computer. Some mention that it serves every function that the Versa 2 had and that most existing features work similarly. However, others say that some features do not work as they would prefer, and some do not operate properly. The tracking is a great draw, but it loses a lot of the functionality that their old smart watch had. It handles texts ok, but does not do phone well, and is practically unusable.

There was a problem filtering reviews right now. Please try again later.
I haven't had this device for months yet, and may update this in the future if I notice different things, but I will say if you go into this with the idea that you're buying a health tracker, you'll get about what you expect. This is not a fancy smart watch and if you want all the music features, additional apps, and things of that nature, this device is not for you. It doesn't function like a smart watch near at all. The music player is limited to Deezer, which I haven't tried. It allows you to navigate Pandora and Spotify on your phone through the device, which is literally the only feature I wanted a smart watch for when I was teaching dance, so for me it's perfect. Almost everything else focuses on your health.
Other reviews have commented on the press point to activate the watch being problematic, but I have had no issues. It doesn't always come on when I turn my wrist to face, which was the same issue with all my previous Fitbit devices. However, the press point to turn it on is basically the same idea as my Charge 3, so maybe that's why I have no issues there.
Not all the newly available metrics have obvious uses. The additional sleep data is very much up for interpretation, but if you keep a log with how you feel when you wake in the morning, any correlation becomes obvious. While I don't know how to interpret this data myself, it is something I've mentioned to my doctor and we will be reviewing on my next visit to help give us a bigger picture of what contributes to my poor quality sleep and other sleep challenges. This is one of the reasons I opted to upgrade when my Charge 3 was still working great and perfectly serviceable.
In additional metrics, we should talk about that EDA scan that's mentioned in all the reviews, but no one seems to understand. I'm actively trying to train myself to make use of that feature. A nifty little thing I've noticed, EDA responses don't appear when I'm under high stress, but they do appear when I've experimented with using the quick scan feature as a non-visual timer for deep breathing in the middle of a anxiety attack. While I don't know if this is reliable, it is giving my medical team more information to try and figure out what's going on, so this may have useful implication in the future.
Another note on the EDA quick scan, as I haven't done any of the guided sessions, it gives you information on your heartrate variability in comparison to your baseline, which I assume is taken from your sleep baseline. Below baseline indicates high stress where above indicates a relaxed state. For me, this has become a useful tool to make sure I'm getting enough exercise, which directly impacts my depression. I know some people out there say "just make sure you get XYZ amount of exercise every day." For me this is giving me useful data on how much and how often is enough to get that number up. Will a run or yoga in the morning be effective for the day? Does an evening routine impact the next morning? It's quantifiable data that I can use as a cue in building my own routine.
I also want to mention the other feature that sold me on this device, the 24/7 heartrate monitoring. Before the pandemic (and became increasingly difficult throughout the pandemic) I had taken up running. One of the things my training app asked was my heartrate during my run. Only problem was I could not accurately get that data as my Charge 3 needed me to remain stationary for an accurate heartrate read. While my heartrate on a run may not have been a necessary detail to include, not having that heartrate often meant exercises were missed and other activities that possibly should have flagged a response didn't. My active minutes have dramatically increased as a result of having more accurate heartrate monitoring. I am also getting a much more accurate look at my activity levels and my calorie intake versus calories burned. This constant data is a lot more useful for anyone who is monitoring their health during exercise, trying to get an accurate calories in/calories out record, and anyone trying to get an accurate picture of what their activity level is throughout the day beyond simply steps to include things previous trackers may have missed. It even picked up on 4 minutes of cardio levels while I was doing an excited sword demonstration for my kids while homeschooling. Is that 4 minutes useful time? Probably not, but it's good to put in my list of activities Fitbit wouldn't have noticed before, but logs now, which also includes dance and other movement exercises that weren't enough to trigger my Charge 3 to identify them as exercise. It was disappointing that 2 hours of dance 3 days a week would often only show up as maybe 30 minutes each day, and sometimes not at all. Those same practices (with an admittedly shorter 30 minute cap due to lack or stamina, thanks pandemic...) are being picked up in their entirety, even if my heartrate elevation is small, but enough to push it into registering in one of the "zones". This has helped a good deal in getting an overall portrait of my health and activity levels, which I'll be bringing to my doctor on my next visit.
The only thing I have found is I haven't been able to get 6 days of battery life out of it, generally landing at 4-5 days. For me this isn't an issue as I don't wear my device to shower and have had a habit since my original Charge HR (way back in the day) of popping it on the charger whenever I shower. This may also be why I don't have any effect from the device or band as my wrist gets regular breaks.
If you're primarily looking for a smart watch and just want something with some extra features, this will not be the device for you. While the extra health tracking is a great draw, it loses a lot of the functionality my old smart watch had, the notifications for things like texts don't always come through (which is fine for me because I don't want that) and the pay feature isn't fantastic. Again, that doesn't matter to me because it's a feature I don't intend to really use anyway, but had to test it out. The apps are limited, and options for music and taking calls aren't wonderful.
On the other hand, if you're looking for a device to give you detailed health information, to accurately log fitness activities, and increased metrics for sleep, this may just be the device for you. It's the best fitness tracker I've seen so far, and this is giving my medical team some new information to work with, which may or may not be useful in the long run, but looks promising. That EDA quick scan had potential for people who suffer clinical anxiety or even PTSD as it can be used to cue deep breathing, and the resulting data may result in creating a better profile of what's going on during an attack, or at the very least can result in creating a cue to take specific actions in a way that simply feeling in the moment cannot. Not all of this data will be useful for everyone, but it could be useful for someone who needs this kind of data to help understand their sleep patterns, anxiety levels, how activity, even in small amounts of a few minutes here and there, impacts their mental health, or even just someone who wants an accurate profile of their physical fitness throughout their exercises.
I was 100% resistant to the idea of yet another smart watch, but in the end I'm happy I made the switch. The added information I've gained has given me a lot more understanding of what's going on with me. I now have clues as to why nights I get plenty of quality sleep (according to previously going on just my sleep score) I wake up feeling tired, and I'm seeing a correlation with sleep temp particularly and low quality sleep. That 24/7 heartrate has been huge. I can now actually monitor my activity level instead of trying to track exercise my Charge missed (because I never turn on exercises prior to start as I never remember or can't figure out which fits best), and result in trying to figure out a routine that way. Everything is logged now, making it simple and accurate. The EDA scan is becoming a tool to manage my anxiety, and while the metrics may or may not be useful, it does cue activities which are useful, so even if it's no more than placebo effect, the end result is valuable.
What you will get out of this device will be very personal and it depends on how you use it, and what you expect to get from it. The Fitbit Sense can be a useful tool for you and your medical team, or even you and your trainer, depending on your goals. This device is definitely not for everyone, and the price point does not make it worth it for every user, but if you're looking for a tool to track your health, this one seems to be the best on the market to date.
The pins on the charging cord fail after a few months. Their are 4 pins inevitably one or more of the pins recess and do NOT connect to the watch to charge. Can’t be fixed so you have to KEEP BUYING new chargers. I’m on my 4th after just a year!
I’ve had mine 3 months. Stopped charging, after intermittent charging issues. Checked, cleaned, the works, nothing worked. Then checked the prongs on the charging unit, 1 was loose! Called Amazon, very helpful and gave me the fit bit tech number. Called explained the issue mentioning the charger prong. Told me yes that was the problem, sent me a new charger. Now charging much faster. GREAT SERVICE from BOTH Amazon and FITBIT!!!
All the features I love about Fitbit watches, sleep stats, fitness stats, continuous heart rate, notifications, are there and working very well.
Initially I found the new UI a bit confusing. Not having the physical 'Back' button on the watch set me back a bit. I struggled for a while on how to get back to the watch face from various situations. Things improved much better when I eventually discovered the "VIRTUAL BACK" button. If you gently press the middle left side of the watch, it gives you a haptic feedback and puts you right back to the previous screen. Otherwise most existing features work similarly. Swipe to the left, you get the application list. Swipe down you get the notifications. Swipe up you get the enhanced fitness statistics as well as weather widget and EDA widget. Fitness stats have been broken into two: CORE and ADVANCED. You have to load the ADVANCED stats separately if you want to see it all.
NEW FEATURES:
If you swipe to the right, you get the most commonly used settings. 'Do not disturb', 'Sleep', 'Always on', 'On when arm moves' buttons as well as watch face dimmer and music volume. These are very useful to have easy access to. I'm keeping the 'Always on' mode on at all times and turn off the 'On when arm moves' setting. This way I can always see the time at a glance and use the 'virtual back button' to light up the watch face when I want. I put my watch to sleep mode before going to bed. I use the virtual back button to wake the watch up and turn off the sleep mode when I wake up. With these settings, my battery lasts about 5 days.
ECG: This is an app in the application list. When you want to take your 30 second ECG, you start the app, place two fingers on the watch face corners and let the watch measure your ECG. After 30 seconds measurement, the watch tells you if you had a-fib during the 30 second time it took the measurement. It doesn't continuously monitor your heart rate looking for a-fib. I guess the idea is when you are not feeling well or having heart palpitations, you will manually start this app and measure it.
SKIN TEMP: The watch measures your skin temperature while you sleep and compares it to your baseline temperature. The idea is that a large variation in your sleep temperature may be an early indication that you are soon to get sick.
EDA: Allows you to relax and measure your stress level for two minutes at a time. Afterwards it gives you a number indicating your stress level. You can also log your mood periodically and the Fitbit app keeps track of it. I find this feature marginally useful if at all.
CHARGER: The new charger is much smaller and slimmer than the old versas. It has four small pins that connect to the watch on the back side. It reminds me of those old pebble watch chargers, where after a while dirt and sweat got in between the pins and contact with the watch became difficult. I had to frequently wipe clean the charger and the backside of the watch with wet wipes so that it could continue to charge. It remains to be seen if this new charger will develop those same problems as old pebble watches. I was hoping for touchless charge, like those of apple watches. Unfortunately not in this release...

So if you want a watch that will last approximately 2 years, develop issues that fitbit is aware of but won't admit or address....this watch is for you. If you want a fitness smart watch that lasts until you're ready to upgrade to new technology and holds its value so you can gift/resell it...pick another brand. So very disappointing. Go ahead and Google fitbit sense stuck on logo.....it's very common, wish I knew but sadly I trusted the brand

Switching on and off is a problem. May be I am not doing it right.
Tracks well.
Solves the purpose of a fitness tracker.
Mich hat das Schlaftracking beeindruckt, denn es gehört zum genauesten, das Nutzer haben können. Da gibt es natürlich noch den Oura Ring, aber dann würde ich persönlich das Display vermissen. Dieses ist einfach super, auch in der prallen Sonne kann man alles gut ablesen. Schick ist sie auch, selbst an sehr schmalen Handgelenken.
Das andere große Plus ist die große Motivation zu mehr Bewegung und Cardio. Sozusagen der Personaltrainer am Handgelenk. Super ist auch, dass ich sie mit zum Schwimmen nehmen kann und auch beim Duschen nehme ich sie nicht ab. Tipp: Aufpassen, dass die Fitbit nicht direkt mit Conditioner, Body Lotion und Co. in Kontakt kommt.
Mit der App kann ich ebenfalls mein Essen dokumentieren und meine verbrauchten Kalorien einsehen. Wenn ich Gewicht verlieren möchte, kann ich also genau sehen, ob ich mir das Stück Kuchen noch gönnen kann oder nicht... Kalorien zählen muss man ja auch nicht immer, aber wenn man es einmal konsequent macht, bekommt man ein besseres Gefühl dafür.
Bin gespannt auf die vielen neuen Funktionen und ob ich das Premium Abo nach Ablauf der Testphase behalten möchte.
Nachtrag: Die Sense trage ich mittlerweile über 12 Monate. Das Premium Abo brauche ich nicht. Bin auch so sehr zufrieden. Einziger Bug: Die Treppenstufen werden falsch gezählt. Immer! Auch nach Neustart und gutem Abtrocknen nach dem Schwimmen. In dieser Preiskategorie schade. Habe gelesen, dass viele Nutzer dieses Problem haben. Mal sehen, wie es mit der Sense 2 dann wird.
