   MS – April 12, 2025

   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.

   I ummed and arred for a long time before buying this watch. In the end I decided that I didn’t want a smart watch, I wanted a decent fitness watch that would give me all the stats I need to track my general health and fitness. And that’s exactly what I got.

   The fitbit app is easily the best app I’ve used, it links with myfitnesspal to give me a real time calories in vs calories out (CICO) and the free trial of premium means I also have easily digestable articles and recipes to support my weight loss.

   I love that there are so many faces to choose from and you can design your own in a separate app. The EDA stress tracker with guided meditation is also excellent if you can take 2 minutes a day for some mindful breathing and meditation.

   Is it worth the extra £100 over the Versa 3? I’m still not sure. After a month I think I’ve used the ecg maybe 3 times and the skin temperature is useful only because I have a neurological condition that’s affected by my body temperature and I’m hoping it will give me an early warning before flare ups. If I didn’t have that I’d probably have gone for the Versa 3.

   I bought this as an upgrade for a Charge 3 as I wanted to be able to access more health information, I did not buy it as a smart watch which to be honest is probably a good thing as it really isn’t one (yet?) I don’t use the voice features, call making feature, Spotify or most of the apps.

   Pros.
   I am impressed with the sleep tracking and all the other associated features which allow you to collect a large amount of health data. This of course relies on a Premium subscription. I have had no issues with the side button which some users have and the display can be viewed clearly even in bright sunlight of which the inability to do this was one of the major niggles of the Charge 3. This device also works with the Cardiogram app which was a question I was unable to find the answer to until after I’d bought it, it’s not listed as supported on the app details and I couldn’t find the answer online. Even though it’s a large watch it’s comfortable to wear night and day.

   Cons.
   Battery life, battery life, did I mention battery life. How Fitbit can claim six days is quite beyond me. Bear in mind I’m not using the ‘battery draining’ features and I needed to recharge on day 3. I turned off the GPS which has to be done on the watch itself not within the Fitbit app, no change. I ran the snore detector for a few nights and realised what I had always suspected, I don’t really snore so I turned that off too but I’m still charging on day 3. Most of the charge seems to go overnight so I guess it’s all the extra data collection during sleep that’s doing it. I have noticed that the charger is quite fussy about where it’s plugged in and charges faster when connected straight into a USB port and not into a mains adapter. I didn’t like the strap supplied so bought a cheap and cheerful fabric one which is really comfortable. I do worry about the robustness of the screen as it’s quite big and vulnerable to knocks and most screen protectors seem to prevent some of the features from working.

   To sum up. This device does what I bought it for which is to provide health data. I did not buy it as a smart watch and had I done so I would have been disappointed. It has lots of really useful features but the one factor which really lets It down is the poor battery life. Even with lots of features unused it is still half of that advertised by Fitbit. I think it’s important to be realistic in your expectations of this device as in reality it’s not where Fitbit would like it to be (or advertise it to be) in terms of its performance especially with regard to realistic battery life. I’ve given four stars as it meets my expectations but taken one off for the battery life issue.

   Update. July 22. As predicted a couple of small chips on the edge of the watch face caused by knocking it accidentally against things. The charger which came with the Fitbit stopped working earlier this week. The cheap unbranded alternative from Amazon seems to charge the device much faster than the original did….

   Update. September 23. I have finally dropped Fitbit and purchased a Garmin watch. Reasons as follows,
   Battery life on Fitbit is dreadful and getting worse.
   Continued issues with the charger failing and no resolution from Fitbit.
   Fitbit have issued an update which has completely ruined the layout of the app and which cannot be changed. In addition since the update my Sense has failed to track my sleep.
   Fitbit has been taken over by Google and the Fitbit app will soon be removed and Fitbit will only be accessible via Google.
   My Garmin device gives me everything that Fitbit did with the exception of ECG monitoring (which I suspect wasn’t very accurate anyway) and flights of steps but without any premium subscription which saves me £80 a year.
   Sorry Fitbit but it’s goodbye from me.

   So I got this delivered on lauch day (25th September) and have worn it every day and night since.
   I have had many fitbit trackers in the past and the last one was the Ionic. I gave up on the Ionic after a year because I had so many issues with it, the worst being it would loose connection with my phone for no reason and then I had to unpair, delete and re install time and time again.
   I have been using the Samsung galaxy watch active 2 since and it was an excellent smartwatch but its fitness tracking was not good mostly because of the calories burned during exercise which was so off.
   I was excited to see the Sense on the fitbit website before it launched and I decided to treat myself. I always buy from Amazon because their customer service and aftercare is excellent.
   Putting it simply I love this watch. It looks great, feels premium and the screen is bright and clear. I’m fully used to the haptic button and prefer it to an actual button as it means that the watch will be better protected from water.
   My only problem is that when doing strenuous exercise like spinning the heart rate sensor takes a while to register the high heart rate reached, sometimes my heart rate slows a bit before the watch catches up which meand I miss out on the top range readings of my heart rate. Also the watch seems to think my heart rate drops down into the 110 to 120 bpm after an intense interval but my heart rate is definitely still really high in between hard efforts so this does bother me. My Ionic did this when I first got it but it seemed to improve over time so I’m hoping that the Sense does too. My guess is that it is something software related which can be fixed. Also when weight training the watch puts my heart rate at 110 to 120 bpm when I know that after doing squats for 6 solid minutes with a weights bar my heart rate is way higher, my Samsung puts my heart rate at 140 to 150 bpm for this. Walking seems accurate as does martial arts and kick boxing. Maybe fitbit could fix this with an update.
   All of the features of this watch are great and I love it. I’m looking forward to seeing what updates come in the future to improve things. I’m especially looking forward to being able to answer phone calls on the watch as this was a big feature I enjoyed with my Samsung. The new os is nice and the connection to the phone is way more stable but it did drop out once so far and I had to unpair, delete and re install then it worked. I think that fitbit might be working on stability now as it needs to be better to be able to take calls on the watch so I’m guessing that’s why we don’t have that function yet.
   All in all I’m happy despite the niggles. I find this watch exciting.

   Update!
   My sense had to be sent back to fitbit today as it was faulty. I’m very happy with fitbit customer service so far as they are replacing my sense with very little effort to action this.
   Unfortunately though Amazon now don’t replace faulty products after the 1st 30 days. They used to replace faulty products up to a year after purchase which is why I bought it from them. I will just buy from the manufacturer in the future now. I have to say the Amazon customer service lady was excellent, not her fault that the procedure has changed. Just thought this might be an important point to make incase anyone else buys from Amazon because of the returns policy which has now changed.

   J’adore cette montre en tout premier lieu parce que la batterie tient presque 1 semaine ! Je la trouve jolie, de la bonne taille pour une femme. L’écran est très lisible.
   L’appli est agréable, je l’utilise principalement pour suivre mon sommeil et mes activités sportives mais aussi pour enregistrer mes repas.
   Les seuls – : l’activation automatique lorsqu’on tourne le poignet fonctionne mal, pas bcp de choix d’écrans gratuits

   Soy clienta asidua de Fitbit desde hace casi 7 años, me encanta su plataforma pues es muy amigable. Dentro de los monitores también representa uno de los más baratos y con el diseño más lindo. Cambié al fitbit Sense, pues mi monitor anterior, el Versa, dejó de funcionar. Ese es el único tema con el que me he enfrentado con la marca Fitbit; sus devices no me duran más de 2 años, y encuentro que no son tan impermeables como se presume, pues cada que dejan de funcionarme es porque nadé con ellos varios días (en mar, albercas, cenotes). Me parece que el Sense podría ser distinto al no tener botones como tal, sino un tipo de sensor que funciona como lo hacían éstos y así no hay manera de que se cuele agua en el monitor.

   Me parece también que el soporte técnico es muy bueno, pues como lo conté en las líneas anteriores, mis devices dejaban de funcionar y fitbit se encargaba de apoyarme e incluso enviarme nuevos monitores. Esto es lo que más me ha convencido de la marca; están comprometidos con el usuario.

   Dentro de los assets adicionales que Fitbit tiene; hay rutinas de ejercicio que puedes ver desde el monitor o la app del celular; tiene foros de discusión; cuenta con una versión premium para tener acceso a contenidos para cuidar tu salud, más entrenamientos, etc (yo no la he usado)

   En cuanto a sus funciones; El Sense trae nuevos assets: medición de temperatura en sueño, medición del estrés, a partir de tocar con la palma entera el monitor durante un minuto. Sesiones de meditación o respiración. Rutinas de ejercicio, métricas promedio de todos tus signos vitales; consejos para mejorarlos. erc,

   La batería me está durando un poco más que el sense, siendo que no estoy registrando todos mis entrenamientos, por lo que mi uso es muy pasivo. El monitor carga más rápido en su charger.

   En el caso del sense, me está sucediendo que no es muy exacto con las métricas de temperatura, e incluso sueño. Mis entrenamientos no se trackean automáticamente, tengo que activar la función de manera manual, cuando antes no tenía que hacerlo en el Versa, el monitor lo identificaba solo. Si lo comparo con monitores como Garmin, me parece que fitbit es mucho más amigable y es para personas como yo, que no somos atletas pero cuidamos mucho nuestro cuerpo y estamos al pendiente de nuestras funciones vitales. En el caso de Samsung, estos son excelentes monitores, pero tienen un precio mayor y te atan a tener un celular de su marca, de Apple ni hablo, porque es una grosería lo que cuestan y no son tan exactos.

   Espero les haya ayudado mi reseña.
