    It’s so easy to use. I’m older and not tech savvy but it wasn’t bad learning how to use it. I’m sure I’m not using it to it’s full potential but I’m using it for what I need. The design is nice, I replaced the straps and added a screen protector. I have a very stressful job and this watch has really helped me with my anxiety. When Im feeling overwhelmed I hide in my office and do the breathing exercises. I can see how my sleeping habits are, and realized I need more sleep. I never thought I’d be a fit bit kind of person but I guess I’m one now.

    Updated Review:I initially gave it a 4 Star rating but just changed it to 5 Stars. I was having difficulty with viewing the daily rating of my Oxygen while sleeping. Some times it would register, other times it would not. I finally discovered that it was measuring my O2 level all the time. The results does not show up right away as you have to wait for a short time to appear.It did show me an upward trend in my temperature, resting heart rate, temperature variability with a downward trend in my Heart Rate Variability (HRV) when I came down with a nasty cold. I could trace it to the date it started.Original Review:The watch is pretty stylish. Comparing it to my sister’s huge Samsung watch, this watch is sleeker and filled with more health features than hers.For accuracy, it is pretty good, but not perfect. I walked exactly 100 steps by counting them out, and the Sense showed 102. I’m pretty impressed with that. The sleep feature seems accurate when it measures the time fell asleep until the time I woke up. Even though it may not be totally accurate against more accurate medical-grade devices, it does give me a baseline and I can measure my progress from that. The heartbeat rate is pretty much on target but I haven’t tested it above 120 where some people have issues with it being accurate.What I find inaccurate: 1) the stairs counter. It misses counting about 4 out of 5 times. If I go down the stairs to the main floor and then back up again, I count 32 steps. 2) I find the SpO2 function pretty useless. First, it is not anywhere close when compared with two actual SpO2 devices. Secondly, sometimes it records while sleeping and other nights it fails to record for no known reason. There are a number of similar complaints and frustration on the Fitbit forum about this same problem. Also, you must use their clock face to record, which I find inconvenient. So, if you are thinking about getting this watch primarily for that feature, I would caution you.Other than that complaint, the watch is quite nice. The charging device is genius, you bring it near the watch, and it instantly connects. Charging times are very short, so that’s a big plus. If you use it to record your sleep and then throughout the day, you might get 2 to 3 days between charges.Nice to have the texting and phone calls feature. Sometimes when I have my phone on vibrate only, I miss the call, but now with the Sense, I feel the vibration on my wrist notifying me of who it is. I can read a partial window of the text message too. When my phone is not on vibrate, I can text the person back through the voice feature. I can answer the call and talk to them through my watch; however, you have to hold the phone near your ear to hear them as the speaker is pretty weak.There is a learning curve if you are a first-time Fitbit user. This is true with the watch and with the App. The App is filled with many graphs and features. It will take some time to learn where they all are located, but eventually you will be able to navigate and find them. Speaking of navigation, if you swipe down on the watch to delve deeper into an app, you can swipe back up, but you cannot go back to the previous feature or forward to the next. You must press the button to go back home first where you must start your navigation over. I hope Fitbit improves upon this feature in the future.The silicone watch band was quite difficult to clasp and unclasp. It wasn’t the most comfortable either, possibly because my wrist was in between the sizing holes. The nice feature of the band is that it only takes a couple of seconds to change them out. I purchased a nice elastic one-piece band that allows me to take the watch off and put it back on within 2 to 3 seconds. Here is the Amazon link: https://www.amazon.com/gp/product/B08KFFSHBH/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1&psc=1 and there are two sizes. I do recommend this band as it comes in a variety of colors and patterns.So, in conclusion, would I recommend this watch? I would say yes as long as you are not needing it for the SpO2 feature which I find unreliable.

    TLDR: glad I stayed with Fitbit vs Apple Watch.I have been a Fitbit User since 2013. I *almost* switched to Apple Watch for this purchase 😱 but I am so glad I did not. With the Sense 2 coming out shortly the discounted price on the first model made it an easy choice. However, even at full retail I would’ve kept with Fitbit.My sister and brother-in-law have both had the Sense for a while, and seeing it in person assured me it isn’t as big/bulky on my wrist as I feared. And also not as delicate as I feared. My sister uses a full plastic case on her screen. I had considered one myself but after finding it impedes the EDA, I opted for a film protection instead. I am a longtime user of the wristband, and would’ve preferred to stick with them. However the EDA sensor and stress management features were what I wanted for this purchase, and since I could only find them in the smart watch, here I am.For battery life alone, Fitbit wins. The Fitbit pay has less banking/card options than Apple pay but it’s not a deal breaker for me. The small band fits tightly, making it uncomfortable and impractical (sweaty and itchy) for me personally; the large band fits comfortably with no complaints. And there are plenty of free custom “clocks” if you’re willing to look (the one pictured is by “Amy,” much love to her and her clocks ❤️ ). I had seen several reviews with concerns about the charging cable pins wearing no out. Asking my sister, they’ve had no issues with either of theirs in over a year of use.Fitbit has become a family affair – we love competing in the various challenges, especially Bingo! Would’ve definitely missed out on this if I had made the switch.

    I am running and training on certain levels of heart rate, pace. It really helps to not just keep of track the actual run series but also my general sense of wellness. I have notice that it is very accurate on predicting when I need to take it easy and adapt my training plan accordingly.The readiness and stress management are the features that I really like from the sense in addition to all other features.I do not use much the smartness related non-health features. But is nice to pay with the it or answer the phone once in a while.

    If you read my other reviews, you’ll note that I *rarely* give low marks and that’s very relevant here. I had specific, narrow-focus interests defined for this purchase, researched that interest with as much care as possible, made a purchasing decision based on those interests and got exactly what I expected. Reading reviews like this are one small part of making that decision, which is why I’m posting mine. Doing that is why I so rarely buy something I don’t like. Due diligence.I’m not rating the app or the sleep tracking because I don’t use them. No idea if they work. I don’t care about how it interacts with my phone, because I don’t want to be seen talking to my wrist and with eyes well over 60 years old I’m not reading my SMS on a screen this small, tyvm.The specific features this model offers which *are* relevant to me over other models – you can infer them from what I haven’t mentioned yet – work well and cost less to have than the offers from competitors, most of whom also think you want to be Dick Tracy. The white/gold aesthetic is minimalist while at the same time receiving compliments from casual observers, and I agree with them. If it gets dirty, I run it under the faucet and clean it. No biggie.Special mention should be made of the included bands. I’m a man of small stature – 170cm – and did not have to resort to the “small” band, instead using the “large” band on its’ second-smallest setting. Fits my particular wrist better that way, although I can also fit the “small” band with less overlap than the attachment regimen (excess band under rather than over) allows. It fits better that way for me, but the important point is that it’s difficult to imagine many human beings exist who can’t leverage one or the other. On the wider settings the darn thing falls off my wrist. *Major* adjustability. It struck me as intelligent design and packaging.It’s what I wanted, and what I thought I was going to get. YMMV if if you want a crossfunctional, true “smartwatch,” which case might justify spending more money on the main competitors’ (admittedly quality) offerings. This one works for me, because I did my due diligence.

    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.

    The Sense is a great Fitbit product. It has way more features than older models and is similar to the Apple Watch from what I can tell (full disclosure, I have not owned an Apple Watch). The sleep tracking is great, although I’m not sure how accurate the timing and scores are. The battery life is great and I have gone 5 days between charges many times.

    The media could not be loaded.

     After lots of back and forth in decision between FitBit Sense and whatever it was AppleWatch… I decided the Sense had more of what I was looking for (health, sleep tracking, statistics of all it tracks, mindfulness practices, etc).I’ve been loving this device for two years now, with minor screen scratches from my own carelessness by scraping the edges on the pool steps. The original strap broke within the first year, which gave me the reason to accessorize with amazing band choices found here on Amazon. That being said, I’ve found the longest lasting bands are the similar flexible material & style that originally came with the Sense.I LOVE the sleep tracking feature which has helped tremendously in mindfulness of my habits & I even get a reminder to start getting ready for bed. Helps a lot. Then there’s the (basal) body temp ‘Sensing’/tracking that has made a big difference in health maintenance, mindfulness &awareness. Of course being able to see the texts from my phone (when devices are synched) and answering phone calls when away from my phone has truly been one of THE MOST HELPFUL advantages to having this thing. Oh- and “Find My Phone” feature- AMAZING! I put my phone down in my house and lose it to the point of regular frustration before I had this watch (I even have designated spots to put it down but somehow don’t )And now, as long as my phone and Sense are synched, I push Find My Phone & the LOUD squawking beep blares from wherever- but sometimes it tells me to try going to a different room & try again- and very rarely has it not worked. The ‘Relax’ part is pretty cool too.Two minute meditations that work wonders for me. Having the Weather right on my wrist really helps, as does tracking heart rate, ECG, specific exercise, EDA/wellness scanner & of course to have the time & date with customizable watch faces. One downside to this device is when my husband is around and I take it off or the band loosens & allows the flashing green lights to be visible (he’s got epilepsy & it can cause Aura)I don’t use a lot of the features on this device & can’t figure out why the temperature switched to Celsius or how to put it back to Fahrenheit, but I’ve also not read how to do so beyond the basic no-duh tries to (settings on device & phone & power off)… then I honestly just decided to take this opportunity to learn Celsius -> plus seeing 35• makes the 95• Fahrenheit weather seem not quite as bad (until I step outside) (and after the first time seeing this change & thinking a freak sporadic ice age has begun (too much sci-fi, I know).So all and all this lil helpful gadget has helped me regain health, mindfulness, less frustrations in daily life & punctuality.So, Heck Yeah I suggest this lil beaut to you too.:)

    Probably want to select reviews based on “most recent” as that will provide you with most up to date and relevant information pertaining to this product. I acquired my Fitbit Sense in June 2021, it has not yet been a month, but so far so good with 24/7 use. I am slow to check out and use all the features, but what I have interacted with so far has been stellar.I have been using Fitbit products since April 2015- kinda have a love/hate relationship with this brand. I use the activity tracker constantly, and I greatly enjoy the app. So I have stuck with it as I upgraded over the years (Charge x2, Blaze x2, Versa 2, and now Sense). As with many Fitbit users, there is a known frustration with the products. Despite some of my own qualms, and having the ability to spend whatever I want on any fitness tracker I want, I still end up (so far) with this brand. Mostly because I haven’t found a tracker and app that I totally like better. I even have a Garmin, but I find that so far off base of accuracy (save for HR), that it is a glorified watch. Garmin seems to do best for actual intended activities (going for a run, going for a long walk, going cycling) where it seems to not be accurate in steps for any other part of the day (only counts about 1/3 of actual steps unless engaged in a longer duration activity, and even then it takes a few minutes for it to start). Also, the app seems to have a lot of info, but doent really tell me anything. That being said, when it was time for me to buy another fitness tracker–I went from Versa 2 to Garmin.. back to Fitbit. I went with the Sense because the price was right, and it was an upgrade over the Versa 2. After my underwhelming experience with the Garmin, I would have happily taken over a 2nd hand Charge from 2015. At least my steps would be accurate.Ok, so back to the Sense. WOW, the visual on the screen is really clear and precise. Even way more so over the Versa 2, and I had no issues with that. Set up was EASY, and QUICK. Basically, just like in adding any other fitbit, just let it pair and it will very quickly be all set and ready to go. I didnt have any weird upselling offerings, or at least nothing that wasn’t fantastically easy to opt out from. Nothing shady that I saw.ONE POINT that I DO think is important to know is that if you happen to have a Versa 2 (Not sure if this also happens with regular Versa, Versa Lite, or Versa 3), but this could not be added alongside my Versa 2. I had to take the Versa 2 offline in order to add this Sense. I know this is the case with trying to add more than one of the same products, yet I have always been able to have several Fitbits paired no problem, as long as they were different models. SO, I guess the Fitbit app sees Sense and Versa 2 as the same. Not a big deal as my Versa 2 had essentially died after I wore it on a hot humid day and my sweat killed it (then I brought it back to life after putting it in a bag of rice for about a week, Then afterward the battery was never the same. It drained to nothing daily.. and I needed to not have to worry about daily charging.. hence my picking up a Garmin in the interim to see if I liked them enough to spring for a more fancy model–nope– and ended up buying the Sense.)Hope it lasts. I love the look. The band is way better than the old pin style. Swapping out bands is so much quicker, easier, less need for super fine motor skills. LOVE the charger. It just sort of magnetizes to the fitbit. No need to clip in.SP02 wasn’t the main feature I was drawn to, but in order to have accurate use it seems a special clock face is needed, and that clock face will drain battery quicker (from what I have read). That being said,Battery life has been excellent for me.Love being able to add other apps, and features. Scrolling is easy, turning face on/off is not complicated.HEART RATE is accurate. I have tested it against my garmin, two blood pressure devices, and a doctors appointment. All saying the same.Also, I the voice assistant is great. You can choose GOOGLE Assistant, OR Alexa. This is why selecting most recent reviews on this sort of stuff is important, as the early release of Sense did not have Google Assistant, but would soon with an update. True, and they followed through as I have it.AT THIS TIME, I have ZERO issues, concerns with this Fitbit Sense. I will be back to update as I learn more, or if I have anything worth sharing that is bad. I keep up with my reviews as needed.

    The magnetic charger works much better than the awkward clip-on chargers of the trackers. The screen is vibrant and looks great. For tracking heart rate, sleep, steps and distance, it seems accurate and reliable.My big hope is that more apps become available for it. As an example, while it connects to pandora, it does NOT connect to amazon music, which I find frustrating. I also feel that, as it is marketed as a smartwatch and not merely a tracker, there is too little available to take advantage of its capabilities and it’s screen.With that said, I like it much more than I did the tracker “Charge” series. It is almost shockingly comfortable to wear, even to bed. I am very happy with my fitbit sense.
