  • Great upgrade from Charge 2
Color: Black/Black Edition: Regular
I purchased this when my Charge 2 started having issues tracking my heart rate during cardio/peak exercise and no longer showed my stats "live" in the phone app (I had to track by looking at the watch each time or forcing a sync). I had a few issues getting the new one to work well with my heart rate too but once I figured it out it worked well. I'll go into what worked and what didn't at the end of my review, because without the heart-rate feature I would rate this a 2... but WITH it, I love the thing and give it a 5. Spotify: I have not used this feature and have no interest in it. I tend to watch streaming shows during my workouts because it's 8,000 degrees outside most days in Texas and I would rather be inside with the AC. Swimming: I am very excited about this feature, but with the current COVID situation I haven't gotten to test it out yet. I like the idea of being able to track my swims as well as my runs though and can hardly wait to try it out. That said, I HAVE worn it in the shower a few times because I forgot to take it off and it survived that with no issues. Comfort and Weight: This thing is significantly lighter than the Charge 2, and the band is easier to change out. It makes it more comfortable to wear while sleeping. Sleep Tracking: This is one of my favorite features, and I like the addition of the oxygen variation tracking. I was hoping that the oxygen tracking would be more than just sleep, but hey, it's nice to know I don't have sleep apnea. The feature basically tells you if you have "high" or "low" variations in your oxygen, and for the most part mine are low. The rest of the sleep feature tracks Awake time, REM time and Light vs Deep sleep. It provides an average trend for your sleep over time, plus a "benchmark" and a "sleep score" so you know how you did. It's helped me be more mindful of my sleep and improve the quality. Heart rate: This tracks my heart rate well and tends to align closely with my treadmill's tracker. I had trouble getting it to read me consistently at first at higher zones, but keeping the watch just below the wrist bone one notch tighter than I normally wear it + using the phone app to look at my heart rate rather than regularly checking the watch helped. That, and I use the watch's exercise app to track the workout now rather than letting it auto-detect like I used to. No issues since. Cardio fitness score: I like knowing where I rank with average and seeing my numbers slowly improve as I get more fit. I wish that there was a feature I could turn on to track pregnancy, however, because your resting rate goes up significantly when pregnant and it lowers your score. Female health tracking: I used to use Fitbit for this. It works well if you keep up with it, but I have another app (Ovia) that I preferred to use once I was trying to conceive. Active Zone Minutes: This feature annoyed me at first. You get twice the minutes for being in Cardio or Peak, and I didn't care to know how many "extra" minutes I got, I wanted to watch my "actual" minutes of workout. Well, at the end the app tells you how many "actual" minutes you get for the workout anyway and as long as you somewhat pay attention to the time (or use your treadmill to track it) you'll know while you're working out too. I get why this is a feature - being in cardio or peak is better than being in fat-burn for calories and workout quality so it encourages you to beef up the exercise, but I was being cranky and resistant to change. GPS: If you do go out and run, GPS eats your battery for lunch. But it's cool to see where you've been Battery: When not using GPS, it's awesome. SO much better than my previous fitbit. Texting and Calendar: I like having the texts in a block instead of scrolling by like on the Charge 2, and the Calendar is always nice. Sometimes you're not with your phone and a tap from your watch to remind you you've got a meeting or an appointment is really handy. Hourly reminders to move: I used this less when I was in the office every day but now that I am pretty much perma-telework it's great. Even if I'm in a meeting I can get up and move and I feel accomplished when I get 9/9! Customizable clock face: Being resistant to change, I liked that I could put the "classic" watch face on my new Charge 4. I appreciate being able to see my step count, heart rate, date and time all at the same time and none of the "new" ones did that for me. The closest one had a sort of circle thing that tracks how close you are to your step count goal but that's not a feature I care as much about so I went back to my old ways. Automatic exercise recognition: I used to use this all the time, but when the Charge 4 was also losing my heart rate, I started using the exercise tracking apps and that seems to help. While it does auto-recognize my exercise that only works if it can read my heart rate properly. Fitbit losing my heart rate: So, when I do my treadmill runs I like to be able to have the app open and watch my count and heart rate there rather than having to look at the watch over and over. When my Charge 2 stopped doing that, I got into the habit of checking my wrist regularly only to find that my heart rate had stopped tracking and I wound up spending most of the workout adjusting the watch to get it to read. It was disappointing to do the full workout and not get "credit" for that work. Yeah, I know, I exercised anyway but I like seeing the trend and the data. So, I bought the new Charge 4 to fix that issue, only to find that it had issues tracking my heart rate as well. After much finagling, I figured out that my new habit of constantly checking my watch was the issue. To resolve that problem, I eventually found that if I used the "exercise" watch app and set it to "treadmill" plus use the Fitbit phone app to watch my heart rate rather than the watch, I have 0 issues getting it to continue tracking my heart rate. I also tighten the band one notch each time and leave it snug just below my wrist bones so it doesn't move so much, even when I sweat. Here's the stuff I tried that didn't work, just to save you some time: 1) Turning the watch upside down 2) Moving the watch higher on my arm and tightening it. My watch tended to slip around more the further it was from my wrist 3) Moving the watch lower on my arm and tightening it. My wrist bends made it lose my heart rate less frequently here, but it still lost it ... show more

  • Fitbit broke after only 4 months. Fitbit voided warranty because I bought it thru Amazon???a
Color: Black/Black Edition: Regular
This is my 4th Fitbit. I cannot believe that Fitbit is not replacing or supporting their product because I bought it through Amazon. It is less than 4 months old. Regular wear then attachments broke off of watch base. No one to talk to in local U.S. only Guatemala, Phillipines etc.

Color: Black/Black Edition: Regular
I've been using the Fitbit Charge 4 for a while now, and it’s an excellent tracker for anyone looking for something simple yet highly effective. The tracker itself is straightforward, without a ton of unnecessary features, Perfect for someone who wants to focus on their fitness without being overwhelmed by too many different notifications, or apps to sift through. My favorite part about the tracker is its incredibly accurate tracking. It consistently nails my exact mileage, whether I’m running, walking, or cycling. The GPS function is also a nice touch, showing my routes on a map through the app, which is really functional and user-friendly, always giving me valuable insights into my workouts. I love how it breaks down my activity and gives me clear data that helps me improve over time, and how I can easily access all my past runs and how much I ran or walked on a specific day. The Charge 4 app also provides all the essentials like heart rate monitoring, sleep tracking, and workout summaries without being cluttered or confusing. It’s easy to navigate and syncs to the tracker with no problem. Overall, the Fitbit Charge 4 is a fantastic choice for anyone looking for a reliable, accurate fitness tracker that focuses on the basics. It’s simple, effective, and does exactly what it’s supposed to do, Which also makes it a great introductory tracker for anyone just getting into fitness trackers, just great performance overall from this device. ... show more

  • My advice... Steer clear of this thing. Wouldn't buy another, wouldn't recommend to anyone.
Color: Black/Black Edition: Regular
So I'll preface my review by saying this is my third Fitbit device, and I looked forward to the Charge 4 with great anticipation. My first I had for about 6 years and only replaced because of a failed integrated band, and the second in 4 years due to a failing battery. I've had the Charge 4 for about 2 months now. Bought it as a first adopter because of the GPS feature (guess that was my mistake.) I need pacing and route tracking for my daily PT, and hate the more advanced but bulky "Smart Watches". With that said, out of the box it looks great, seems to be good quality and with a good feature set. And that's about where it ends. Functionality - The GPS works optimistically about 20% of the time. If it connects at all, it takes about 5 minutes to do so, and if you run/walk/ruck more than a mile it will disconnect multiple times. If you start a workout without the GPS, it may or may not start tracking half way through the workout. This wouldn't be a problem if it weren't for the fact that ALL tracking features of this model use the GPS location for analytics. In an 8 mile ruck, the watch will reconnect about every half mile (or not at all) which means the watch thinks you walked in place for 1.5 hours in 'peak' heart rate, which doesn't accurately calculate pace or caloric burn... Additionally, because of this fault; the auto workout tracking feature generally just stops tracking at all about 10 minutes into any workout because it doesn't think you're doing anything and reverts to the home screen. So as a tracker, it's worthless. Build Quality - While it came out of the box nice and tight the removable band has, in two months, loosened up enough that it will just randomly pop loose at the body connector under normal walking circumstances, rendering the watch useless in your pocket (see pic). I give it another month at best before the band won't attach at all. Operation - They may come out with another firmware update to fix this problem, but if not the watch has to be re-paired with the Fitbit app at least once a week. The app itself is really nice, with some great features, but the Charge 4 looses connection for some reason, and has to be 'removed' and 're-paired' for it to start sending information again. Each time you re-pair, it has to be completely re-configured for messaging etc. I just gave up on that feature... With all of that said, this has turned out to be a $150 dollar heart rate monitor and stop watch, and a glitchy one at that. I'm not at all impressed with the operation and would not recommend to anyone till they figure out and fix the issues. Poor look Fitbit. I'll look at Garmin or something else that may actually work. ... show more
