    • Great watch!
Color: Carbon/Graphite
I’ve had this watch for over 3 years now! It’s still works great and have had no issues with it. The metrics for logging my workout and sleep and my favorite feature without having to pay any kind of extra subscription fees

    • so far so good, excellent clarity, accurate steps & heart rate, easy set up
Color: Carbon/Graphite
UPDATE: 2 FULL YEARS later practically to the date. My SENSE crapped out. Was a good Smartwatch up until it just started not working (only showed fitbit icon, intermittent vibration, would work for a few hours, then go back to showing nothing. Was a quick death). Not changing rating as all these gadgets are basically throw aways. Now back to original review: --------------------------------------------------------------------------------------- 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. ... show more

    • Nice features - needs work
Color: Carbon/Graphite
I’ve been a Fitbit user since 2012 and having used at least 7 different devices over those years (Zip, One, Force, Charge HR, Charge 2-4) - long enough to know where they’ve hit the mark and where they’ve missed it. The Sense was an upgrade from my Charge 4. Where it excels: - Watch face: allows you to choose the face with many free and paid options ($0.50 - $1.50) - Built in GPS (same as Charge 4, handy feature) - Sleep tracking: includes optional SPO2 monitoring with an additional free app installed to the watch - Apps: you have a number of different apps that you can download to the watch - Exercise tracking: Charge let you add your top 5 exercises to your watch for quick add. Sense has the complete list already on it - Water logging: can be done right from the watch (awesome!) - Weather: you can add an app to see the weather on your phone. Supports multiple locations - Music control: right from your watch (Pandora, Spotify, Deezer) - Voice assistant (Google or Alexa), EDA scan, find my phone, answer calls from your watch, full text message viewing, and ECG are new additions from the Charge 4 - notifications to drink water during the day (optional setting) is helpful - Alarm will monitor your sleep to wake you at the most opportune time (not in the middle of REM sleep for example but before/at the time you set) Now for the bad… - Claims to hold a 6 day charge but with basic use and some daily exercising, I find myself charging it every few days - watch faces are nice but you can only keep 5 on hand in your app. If you accidentally write over a paid face, its a pain to get it back without paying for it again - watch disconnects from your phone very frequently requiring one to open the app constantly and sync to restore the connection - find my phone (one of the features I was really looking forward to) rarely works because the watch disconnects from the phone so frequently - ECG regularly says the results are inconclusive despite remaining perfectly still - Missed notifications (calls. texts, calendar, drink water) - a constant issue because the watch doesn't stay connected to the phone - Doesn't seem to sync in the background despite all the settings on the app, watch, phone indicating it should Aside from the frustration around stuff constantly not working because watch disconnects from the phone, the vibrations on the watch are sad - even with vibration turned to “strong”. Additionally, the Charge 4 had different vibrations depending on the notification (reminders vs calls vs texts, etc). The Sense notification vibrate are all the same, and can barely be felt. I don't rely on the watch to wake me up whereas my Charge 4 was an awesome alarm as the vibration was so strong. Am I happy with this watch? Eh. It has a lot of potential if these main issues are addressed by way of software updates or hardware upgrades in v2 Side note: all my complaints are echoed on the Fitbit Community pages which tells me its not a problem with the device I received, its issues with Fitbit Sense in general ... show more

    • Had a Fitbit “forever”
Color: Carbon/Graphite
I was an early adopter of Fitbit back when it was just a little clip thing- the company then was small and had really great customer service, they’d send a new little device if the one you had stopped working. While I’m sure the company is now very different Ive still always had a Fitbit of some kind, I appreciate that Ive had my health data compiled since 2010! This device has been great, I love the smart watches that also track my sleep and vibrate to wake me up, and remind me to get up and move around every hour. The bonus of getting text messages on my watch, seeing calendar reminders pop up, check the weather, etc has been great. I’ll always be a Fitbit customer. ... show more
