Perfect activity tracker and smart watch
Works very well, I can track my activity in different zones including cardio, sleep phases, calories spent, hbr and many other useful features. Helps me to maintain my activity during working hours at tge office from 9 am till 6 pm reminding me to make some steps. Love it!

It is really great
This is one of the best smartwatches I ever bought. I was in Dubai and bought it since it was not available in Egypt. The biometrics are more accurate than my previous Versa 2. The ECG feature is quite amazing as you will get 30 seconds of your ECG which you can share with your doctor if you suspect the rhythm. The temperature and stress measurement is a great addition. Just make sure that you don't make the bank tight as this is wrong, and it could cause some reddish skin underneath it. Even if it is a bit loose, you will still get the metrics.

Great expectations, mediocre performance
The battery life is ok, not the best. The display is ok. The other features like NFC is ok. The mobile pairing can be spotty. But the main drawback is the software. The software is stuck in the stone age. No smart features like exercise auto start and auto pause. Limited health tracking features. The biggest let down is they constantly disable the ECG feature (the reason why I purchased the watch in the first place). Verdict: Save your money and buy something better.

Fitness watch first, smartwatch second.
A lot of complaints here, so I’ll give my OK-to-good experience countering some of the claims. Awful battery life - Don’t know where they’re coming from with that, but I have the charger handy outside the bathroom and I stick the watch there everytime I have a shower. That quick charge keeps the watch going until the next shower(or even the one after that if I so wish). And I use both Always-On(medium bright) and Sp02 tracking, power hungry features. Watch not as snappy, limited phone and app integration - Yeah it’s not really geared to be the smartest watch, nor does it aim to be. I have it relay notifications and control music, but nothing more than that. If you’re looking to organize agendas/calendars and play games, it’s a slippery slope down to stuttertown my friend. I use the watch for light sleep alarms and you can see the frame rates struggle with even the alarm app. Watch breaks easily - I’ve had it for about two weeks now, and after the initial TLC period I went about my routine without really being consciously gentle on the watch. A couple of hard knocks here and there, and the occasional running under the tap to rid of sweat. Watch is as good as the day it came out of the box. My biggest problem so far is the rash spots the watch leave with extended wear. They’re pretty small, and are manageable by alternating hands and positions on said hands(lower/upper wrist), but I feel that you shouldn’t have to do this every other day, especially when switching hands involves adjusting the watch sensitivity via the phone app. At least make it easier for me to change the dominant wrist setting on the watch itself. So. The good things? Fitness tracking. Data, and data trends over time. Data and trend based recommendations. Mindfulness and stress tracking. Sleep tracking. The ‘gamifying’ of fitness goals and stats. If you have all this stuff in mind when you buy the watch, you’re getting your money’s worth I guarantee it. You’ll need a sub to FitBit Premium(6 months’ of which come free with the watch), but that’s not the biggest bite out of the wallet from what I see, nor is the price unjustified(could always be less, but it’s okay atm).

One of Fitbit's finest watches
This watch does many things, and it does them very well : SpO2 measurement (during sleep), recieve calls via Bluetooth and other biological measurements- that you probably never thought of - but may help explain why you feel the way you do when you wake up (and do something about it). With all of its features activated in the region, I recommend over the lovely and fabulous Versa 3. The ability to detect a strange rhythm in your heart is enough to make it my choice.

Disappointed
1. You can't check SPO3 manually as it does while you sleep in night. 2. No ECG tracker is working in UAE. 3. Battery time is good. ( 4 to 5 days)

Even if the watch has always been hard to charge and important features with only with the (expensive) premium subscription, I was features satisfied with the watch. I have also used the charger that comes with the watch; but before you know it the watch doesn't charge anymore. Not citar to me if it's the device or the charger; no matter how much I try the charge doesn't happen. As warranty is so short, you shoot with a watch that you can't use pretty soon. Really feel scammed 😪

Let me first say that I am not a smart watch person. I had the Samsung Watch before and absolutely hated it. I was very resistant to switch from my faithful Charge 3 to a new device that seemed similar to a smart watch, especially one that clearly had features that hadn't been fully sorted out yet. At the same time, some of these features, like the 24/7 heartrate monitoring and improved data for sleep monitoring were definitely a draw. 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.

FITBIT SENSE, UNA QUALITÀ E UNA RAFFINATEZZA PARAGONABILE A UN ROLEX D'ORO, MA PER FITBIT SENSE QUESTO È SOLO L'INIZIO LE QUALITÀ CHE HA ASSIEME ALLA SUA APP. SONO INDISCUTIBILI E LE FUNZIONI SONO PRECISE AL 99%, AVENDO AVUTO ANCHE UN APPLE WATCH, NON ERA A QUESTO LIVELLO COME BELLEZZA ESTETICA E PER LE FUNZIONI CHE FACEVA, MA SOPRATTUTTO PER LA SUA BATTERIA CHE NON DURA NIENTE!!!!!!!! COSA IMPORTANTE AL GIORNO D'OGGI OLTRE LE FUNZIONI DI TENERTI SOTTO CONTROLLO TUTTO IL FISICO, GIUDICO IMPORTANTE ANCHE IL SISTEMA DI PAGAMENTO COMODO PRATICO E SICURO CHE NE INTEGRA QUESTO OROLOGIO. DAL MIO PUNTO DI VISTA DOPO AVER CONFRONTATO IL FITBIT SENSE E L'APPLE WATCH ULTIMA VERSIONE, GIUDICO IL FITBIT SENSE CON UN VOTO 10 MENTRE L'APPLE WATCH DO UN VOTO 8 PER VARIE PROBLEMATICHE!!!!!

Go for this smartwatch only if you don't want any gimmicks that other smartwatches may offer and requires pure overall health tracking. It has accurate and precise health tracking ability. Only thing that it should improve or have is to play songs from Spotify through watch speaker itself.
