    • Returning the Charge 4, Apple Watch is Significantly more accurate... Fitbit more comfortable.
Color: Black/Granite Reflective Edition: Special Edition
Review Image by Saint04 Saint04
I've owned several Apple watches (the series 5 as well)... the extra features are hardly desirable since it requires your phone to be on you (e.g. calling, txt, etc; unless you want to be exposed to even more radiation with a cellular model... even more money). This fitness tracker is comfortable, has aftermarket straps/bands and works across platforms... on an expendable device, including Apple Watch, the price is much better and is just as accurate. I'm very glad Fitbit came out with the Charge 4 and built off their Charge 3 design... sound familiar... Apple ? Proven design with GPS abilities... good call on Fitbit’s behalf... All my devices are Apple ($3k laptop, $1k+ phone, iPads, iPods, etc)... except my Charge 4. Fitbit is focused on those wanting to target on their overall fitness health... Apple Watch is not the most comfortable ( while not bad)... poor battery life and slightly entertaining... great. Fitbit for daily practical use (I don't like jewelry and this is light weight and hardly noticeable). Apple, well, a big fan, just not of an overpriced watch since both of these devices are expendable. I do like how the Fitbit uses Corning Gorilla glass. It could be brighter in direct sunlight but it’s not a huge bother for me (screen is difficult to see in bright lighting outside). ------------------------------- Update: After using the Fitbit Charge 4 for nearly 2 weeks, it has not been accurate. I took it on a few runs and walks using GPS for the auto calibration regarding my stride. I found that the Fitbit is highly inaccurate for the amount of steps taken and distance covered; Side note, GPS distance is accurate... not so much steps taken). Also, sitting at my desk, I can get up to 500 steps in an hour working on my keyboard at the computer with the Charge 4... the Apple Watch doesn't have these issues. My heart rate reported up to 140 BPM on walks, while the Apple Watch maintain around 80-90BPM... the 140BPM is way off. I'm a conditioned athlete and it takes me a minimum of a mile to get my HR up to 140 BPM running (not sprinting). Again, I did calibrate the Fitbit. The Apple Watch as well. What I found was the Fitbit excessively counts steps with arm movements while sitting, which didn't confuse the Apple Watch. However, the Apple Watch will give you standing time when you are not standing... no big deal. However, for my use, the Apple watch is always spot on when I do treadmill runs and providing me general heart rate feedback. While I don't get all the data/metrics that that Fitbit has to offer that the Apple Watch has, I just don't trust it. I tested it against multiple devices and the Fitbit usually seems more than generous to give you credit where it isn't earned. Other than the Apple Watch telling me I'm standing on occasion when I'm not, everything else is spot on. I will be missing the sleep feature on the Charge 4 as it seemed to be spot on and VERY impressive. However, I need the device to be accurate for my fitness. I also appreciate that I can look up my info for the Fitbit in a large layout on my web browser while on the Apple Watch I'm mostly stuck to the phone. For me, accuracy was key with my physical activity and the Fitbit Charge 4 did not provide this. I'm kind of bummed about that as I mentioned in my initial review everything I was excited about until reality and daily use set in. My rating is two stars because the device was nearly pointless for my application regarding fitness and accurate measurements (the whole point in purchasing the device) for distance, steps, and heart rate. It has so much potential and the device is VERY comfortable to wear without having to charge it nearly every day. So, I'm back to the Apple Watch for focusing on more realistic fitness goals and metrics. I tried to give the Charge 4 EVERY benefit of a doubt. If your data is not somewhat/fairly accurate, then it doesn't give you much to work with. For now, I'll be sticking to the clunky Apple Watch with poor battery life, no web data, and sleep monitor (there are 3rd parts apps, but Apple Watch isn to practical for sleep use due to short battery life and slow charge time) because my priority is accurately measuring what I previously stated. For that, the Apple Watch excels. ---------------------------------------------------Update 2 Well, I decided to give the Fitbit Charge 4 another chance. I was able to adjust some settings that made it way more accurate. I wear my watch on my non-dominant arm. However, I put the settings to dominant... now I don't have excessive false steps... actually, it's a little more accurate than the Apple Watch Series 5 I tested it up against. HR is accurate at resting and I have not been able to test this units HR monitor while active... fingers crossed this unit is more accurate than the last. Another bother for me using my Apple Watch is that I'm tied to the phone to observe my data. I appreciate that I can login to my Fitbit account online to look at my metrics/data instead of being tied to the app on a phone. ------------July 6, 2020--- Worthy updates released. Fitbit added some pretty cool feature in the most recent update. There is a dynamic GPS update. Basically, when you want to use GPS, it'll default to your phone if you have it on you and then to the device if your phone is unavailable. That was a concern I had because the GPS function does drain the battery quite a bit during my bike rides and most of the time I have my phone with me... good stuff. A "smart wake" feature was added as well. Basically, if determines your sleep schedule and the best time to wake you up... probably good for those that don't have a set work schedule... as a student at the moment, it is a hand feature to have to prevent oversleeping, etc. There is now an option to adjust how long the screen stays on for. Good to have... it was getting annoying having to double tap the device every time the screen timed out. Then various bug fixes... ---------------Update July 8, 2020 I decided to return the Fitbit Charge 4. It is an excellent contender for those focused on fitness. My main gripe was that the Fitbit platform does not readily sync with other apps such as Garmin and Strava. Another considerable issue is that I could not see the screen well outside during runs and biking... and it is difficult to start stop/activities outdoors with sweaty hands (no physical buttons (more competitive than physical press) other than the one on the side). Since I use an Edge for my road bike, I decided to get a Garmin watch (Instinct) considering it readily syncs with Strava, Garmin Connect and my cycling computer. My main glaring issues were screen readability outdoors and app syncing. If not for these issues, I'd likely been more than happy with the Charge 4. For the price, I definitely recommend it for those if this is the only platform they depend on to track their health and fitness. Sleep tracking is really good as well as the step count once you get everything honed in. ... show more

    • 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
