What is zap zone built-in GPS; heart rate sleep and swim tracking; black/black One Size (Includes S&L Bands) Fitbit Charge 4 Fitness and Activity Tracker gifts for friends?


      I purchased this when zap zone my Charge zap zone 2 started having issues tracking my heart rate during zap zone cardio/peak exercise and zap zone no longer showed my stats "live" in zap zone the phone app zap zone (I zap zone had to track zap zone by looking zap zone at zap zone the watch each time zap zone or forcing a sync). I zap zone had a few issues getting the new one to work well with my heart rate too but once zap zone I zap zone figured it out it worked well. I'll zap zone 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... zap zone but WITH it, I love the thing and give it zap zone a 5.Spotify: zap zone I zap zone have not used this feature and have no interest in it. I tend to zap zone watch streaming shows during zap zone my workouts because it's zap zone 8,000 degrees zap zone outside most days zap zone in zap zone Texas and I would rather be inside with zap zone the AC.Swimming: I am zap zone very excited zap zone about this feature, zap zone but with the current zap zone COVID situation zap zone I haven't zap zone gotten to test it zap zone out yet. I zap zone like the idea of being able to track my zap zone swims zap zone as well as my zap zone runs though zap zone and zap zone can zap zone hardly wait to zap zone try it out. That said, I HAVE worn it in the shower a zap zone few times because I forgot to zap zone take it off zap zone and it survived that with no issues.Comfort and Weight: This thing is significantly lighter zap zone than the zap zone Charge zap zone 2, and the band is easier to change zap zone out. It makes zap zone it zap zone more comfortable zap zone to wear while sleeping.Sleep Tracking: This is zap zone one of zap zone my zap zone favorite features, and I like the addition of the oxygen zap zone variation zap zone tracking. I was hoping zap zone that the oxygen zap zone tracking would be zap zone more than zap zone just sleep, but zap zone hey, it's nice to know I don't have sleep zap zone apnea. The feature basically tells you zap zone if you zap zone have "high" or "low" variations in your zap zone oxygen, and for zap zone the most part mine are zap zone low. zap zone The rest of the sleep feature zap zone tracks Awake time, REM time and zap zone Light vs Deep sleep. It provides zap zone an zap zone average zap zone trend for your sleep over time, plus a "benchmark" zap zone and a "sleep score" so you know how you did. It's helped me be more mindful of my sleep zap zone and improve the quality.Heart rate: This zap zone tracks my heart rate zap zone well zap zone and tends to align zap zone closely with zap zone my treadmill's tracker. I had trouble getting it to read me zap zone consistently at first zap zone at higher zones, zap zone but keeping the watch zap zone just below the wrist bone one notch zap zone tighter than I zap zone normally zap zone wear it zap zone + using the phone zap zone app to look at my zap zone heart rate rather than regularly checking the zap zone watch helped. That, and I zap zone use zap zone the zap zone watch's exercise app to track the workout now rather than zap zone letting it auto-detect like I zap zone used to. No issues since.Cardio fitness score: I like zap zone knowing zap zone where I rank with average and seeing my numbers slowly improve as I get more zap zone fit. I zap zone wish zap zone that zap zone there was a zap zone feature I could turn on zap zone to track pregnancy, however, zap zone because zap zone your resting rate goes up significantly zap zone when zap zone pregnant and it lowers zap zone your score.Female health tracking: I used to use Fitbit for zap zone this. It works well zap zone if you zap zone keep up with it, zap zone but I have another zap zone app (Ovia) zap zone that zap zone I preferred to use once I was trying to conceive.Active Zone Minutes: This feature annoyed me at first. zap zone You get twice the minutes for being zap zone in Cardio or zap zone Peak, and I didn't zap zone care to know how many "extra" minutes I zap zone got, I wanted zap zone to watch zap zone my zap zone "actual" minutes of workout. Well, at zap zone the end zap zone the app zap zone tells you how many "actual" minutes zap zone you get for the workout anyway and as long as you zap zone somewhat pay attention zap zone to the time (or use your treadmill to track it) you'll know while you're working zap zone out too. I get why zap zone this is a zap zone feature zap zone - being zap zone in cardio or peak zap zone is better than being in fat-burn zap zone for calories and zap zone workout zap zone quality so zap zone it encourages zap zone you to beef up the zap zone exercise, but I was being zap zone cranky and resistant to zap zone change.GPS: If you do go out and run, GPS eats your battery for zap zone lunch. But it's cool zap zone to see where you've beenBattery: When not using GPS, zap zone it's awesome. SO much better than my previous fitbit.Texting and zap zone Calendar: I like having the texts in a block instead of scrolling by like on the Charge 2, zap zone and the zap zone Calendar is always nice. Sometimes you're not with zap zone your phone and a tap from your zap zone watch zap zone to zap zone remind you zap zone you've zap zone got zap zone a zap zone meeting or an appointment zap zone is really handy.Hourly zap zone reminders to move: I zap zone used this zap zone less zap zone when I was zap zone in the zap zone office zap zone every day but now that I zap zone am pretty much perma-telework it's zap zone great. Even if I'm in zap zone a meeting I can zap zone get up zap zone and move and zap zone I feel accomplished when I get 9/9!Customizable clock zap zone face: zap zone Being zap zone resistant zap zone to zap zone change, I zap zone liked that I could put the "classic" zap zone watch face zap zone on my new Charge 4. I zap zone appreciate zap zone being zap zone able to zap zone see my step count, heart rate, date and time zap zone all at the same zap zone time zap zone and none zap zone of the zap zone "new" ones did that for me. zap zone The closest one had a sort of circle thing that tracks how close you are to your zap zone step count goal but that's not a feature I care as much zap zone about so I went back to my zap zone old zap zone ways.Automatic zap zone exercise recognition: I used to use this all the time, but when the Charge 4 was also losing my heart rate, I started zap zone using the exercise tracking apps and that zap zone seems zap zone to help. zap zone While it zap zone does auto-recognize my exercise that only works if it can read my heart rate properly.Fitbit losing zap zone my heart rate:So, when I do zap zone my treadmill runs I like to be able zap zone to have the app open and watch zap zone my count and heart rate there rather than having zap zone to look at the zap zone watch zap zone over and over. When my Charge 2 stopped doing zap zone that, I got zap zone into the habit zap zone of checking my zap zone wrist regularly only to find that zap zone my zap zone heart zap zone rate had zap zone stopped tracking and I wound up spending most zap zone of zap zone the zap zone workout adjusting the watch to get it to read. It was disappointing to do the full workout and not get "credit" for that work. zap zone Yeah, zap zone I know, zap zone I exercised anyway but I like seeing the trend and the data.So, zap zone I bought the new Charge 4 zap zone to zap zone fix that issue, only to find that it zap zone had issues zap zone tracking my heart rate zap zone as well. After much finagling, I figured out that my zap zone new habit of constantly checking my watch was the issue. To resolve that zap zone problem, I eventually zap zone found that if I used zap zone the "exercise" zap zone watch app and zap zone set it to zap zone "treadmill" plus use the Fitbit phone app zap zone to watch my heart rate rather than zap zone the zap zone watch, I zap zone have 0 issues zap zone 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 zap zone it doesn't move zap zone so much, even zap zone when I sweat.Here's the stuff I tried that didn't work, just to save you some zap zone time:1) Turning zap zone the watch upside down2) zap zone Moving the watch zap zone higher zap zone on my zap zone arm and tightening it. My watch tended to slip around more the further it was from my wrist3) Moving zap zone the watch zap zone lower on my arm and tightening zap zone it. My zap zone wrist zap zone bends made it lose my heart zap zone rate zap zone less frequently here, but zap zone it still lost zap zone itSo this zap zone is my 3rd smart wearable zap zone device I have zap zone owned. zap zone I zap zone have had zap zone the original Moto 360 and zap zone I currently have the very zap zone old (in electronic years) zap zone Huawei watch. I will start off by saying zap zone that this Fitbit zap zone Charge 4 zap zone is way zap zone more comfortable zap zone than the zap zone previous two device. Once on your zap zone wrist you will forget that it zap zone is there except when zap zone it buzzes on your wrist for notifications. Speaking of notifications, they work very nicely without being over bearing. You can choose and select from which apps zap zone you want to get notifications on, for example all I care about is notifications from WhatsApp, Messenger and my Emails so that is all zap zone I have it set to. You also zap zone will get zap zone notifications about you activities which you zap zone can also change if you feel your getting zap zone too many. I left all settings at their defaults and I do not find I get to many notifications. I zap zone walk 5 days a zap zone weeks and workout 3 days a week and zap zone the Charge 4 automatically zap zone tracks my walks perfectly. As for my workouts it doesn't seem to know zap zone when I am doing pushups or pullups and of zap zone course it will zap zone not pick zap zone up the fact I am doing zap zone planks zap zone but zap zone that is zap zone ok as I zap zone doubt I zap zone am burning zap zone a zap zone lot of zap zone calories from my 3 day a week workouts as it zap zone is more for muscle toning and trying zap zone to keep a flat stomach zap zone in zap zone my old age.Sleep tracking on zap zone the Charge 4 is zap zone very nice! zap zone I zap zone have had zap zone a zap zone sleep zap zone study zap zone done about 7 years zap zone ago and they said I stopped zap zone breathing 4 times during the night zap zone of zap zone the test but that it was zap zone not severe enough to warrant a CPAP. This tracker zap zone has a SP02 sensor so in the morning I zap zone can check zap zone to see how many zap zone times my blood oxygen dropped low zap zone during the zap zone night and so far it zap zone has zap zone only zap zone been zap zone a couple times zap zone over zap zone the zap zone 17 days since it has started tracking my sleep. So that makes me feel a bit zap zone better knowing I really do zap zone not zap zone have a Sleep zap zone Apnea problem. It would be nice if zap zone Charge 4 gave you more detailed blood oxygen information, like percentages during the night, but that might something to due with zap zone the fact that this is not a medical zap zone grade device and they do not want people thinking that or they don't want to have to go through the process of zap zone getting certification zap zone for it which zap zone would cost a lot zap zone and zap zone effect the zap zone cost of the device. Also it does not have OnDemand zap zone for SP02 reading, zap zone it only checks it at night. It would be nice if they zap zone added OnDemand SP02 checking. From reading over on zap zone the zap zone Fitbit forums it zap zone might zap zone be added in the future zap zone so that would be a big plus, especially for runners.The Charge has 24/7 heart zap zone rate monitoring and they use this along with movements to zap zone track your sleep and give you a really detailed Sleep Score. It will show you zap zone REM, Light, Deep sleep and time awake during zap zone the night. From what I zap zone can tell it is mostly accurate as zap zone it seems to match zap zone up zap zone perfectly to when I zap zone have gotten up to go to the zap zone bathroom or let the cat in or out etc. and the REM seems to zap zone match up to zap zone when zap zone I was dreaming the times that I woke zap zone from zap zone my dreams zap zone for what ever reason and checked the zap zone time. If I ever do another sleep zap zone study zap zone it would be zap zone neat to check the results verses the Charge 4 but I feel it gives you a very good idea zap zone of zap zone how your nights sleep was. When my zap zone score zap zone is high like in the zap zone 80s zap zone I feel zap zone refreshed in the morning but zap zone when it was low zap zone a few times (73) I felt zap zone tired and needed a long nap zap zone in the zap zone afternoon to recharge. Speaking of naps, it zap zone will track zap zone your nap so long as it is over zap zone 1 hours but will not give you any detailed zap zone info about zap zone your nap zap zone like zap zone it zap zone does for zap zone night time sleeping.Functionality wise, zap zone I like how zap zone the Charge 4 wakes when you lift you arm. My Huawei watch is hit and zap zone miss when I raise my arm zap zone but the Charge 4 zap zone seems to zap zone be zap zone about 95% of the time. The zap zone touch to wake screen zap zone I wish was a bit more sensitive, it works fine after it has been woken zap zone from lift to wake zap zone but if the zap zone Charge zap zone 4 has been a sleep zap zone for a while zap zone and you zap zone try and tap to wake I find I zap zone have zap zone to tap it a few times. This effect me when I am using zap zone the Stop Watch zap zone feature to time zap zone my planks, I can zap zone not zap zone lift my arm to zap zone wake it zap zone during planks and zap zone trying to tap it to wake it to see if I zap zone have hit my zap zone time zap zone on the Stop Watch can be zap zone a pain.Scrolling zap zone on the watch zap zone is smooth and fast but they need zap zone to fix the firmware so that zap zone once you zap zone leave the main menu, say to go zap zone into settings, you zap zone can not swipe right to go back, you zap zone are zap zone forces to press the haptic button to go back which is a pain. zap zone I started a Feature Suggestion to get it added over on the zap zone Fitbit forum zap zone so feel free zap zone to up zap zone vote zap zone it.The display is crisp and bright and zap zone easy to read even zap zone outside. With my Huawei zap zone watch I could not see anything zap zone on the screen zap zone while outside. The font is zap zone large enough that I can see most of the zap zone information without my zap zone glasses on so that is really nice as I only put them on for zap zone reading and of course take zap zone them zap zone off zap zone when I am exercising.About the only I miss from my Huawei watch is music zap zone control. You should be zap zone able to pause / play and zap zone skip tracks of whatever app is playing zap zone music on your phone. zap zone Not sure why they didn't add zap zone this in yet as the zap zone Charge 4 is always zap zone connected to the phone via zap zone Bluetooth zap zone so it zap zone should be zap zone able to do zap zone it with a zap zone simple firmware update. Even cheap zap zone bands zap zone out zap zone there zap zone have this simple zap zone feature.The other feature zap zone missing but I zap zone do not miss is a mic for Google Voice command and a zap zone speaker to take zap zone calls on your wrist. While it is cool to zap zone do this to show off who really want to talk to your wrist to ask zap zone Google zap zone something zap zone or zap zone worse to try and have a conversation with someone that everyone zap zone around you would be able zap zone to listen in onAs far zap zone as battery life, they claim 7 days and zap zone I am seeing that. zap zone I think even 8 days zap zone are zap zone possible. There zap zone is zap zone an option to have the screen stay on longer when it zap zone wakes but that seems to take a day off the battery life. There is also a Feature Suggestion to add a Always On Display AOD over zap zone on the zap zone Fitbit forum to the Charge zap zone 4 but I zap zone think the battery would take zap zone too zap zone much of a hit if they added it. I think zap zone Fitbit did a zap zone good job with zap zone features zap zone and zap zone battery life with the Charge 4 zap zone as it stands now. Maybe zap zone in zap zone the zap zone Charge 5 with a zap zone larger zap zone capacity battery zap zone they could then add a AOD and maybe a color display that is even bigger but zap zone with the current battery technology I think zap zone they did a good job with zap zone the Charge 4. I like only having to charge zap zone mine once a week. zap zone Note: I have my Charge zap zone 4 set zap zone to GPS zap zone Mode zap zone Dynamic as I have my phone with zap zone me when zap zone I take zap zone my zap zone walks. zap zone If you leave your phone at home the Charge 4 will automatically use its built in GPS zap zone which will drain your battery zap zone faster. So keep that in mind if you zap zone like to zap zone take your walks and runs without taking your phone. One zap zone week soon I zap zone will try a complete week without taking my phone with me and will update this review zap zone with how long zap zone the battery zap zone lasts so you can get an idea.The other thing zap zone I really like about the Charge 4 zap zone over others out there (I was looking at the Garmin Vivoactive 4) is zap zone that the band is changeable! As you can see in my photos I have 3 different zap zone bands, two came with zap zone the zap zone Fitbit Charge 4 Special zap zone Edition and I purchased the Fitlink Stainless to give it a zap zone "Classy" look.When you get zap zone the Charge 4 it will be zap zone on an older version of firmware, which just means it needs to be updated, you can zap zone not force it to update zap zone and so you have to wait for it to update. Mine took 20 hours zap zone to finally zap zone say there zap zone was an update available. I zap zone have read it can take two days. So be patient. I know that this zap zone sucks but I think they zap zone do it that way zap zone as zap zone to not drain the battery on the Charge 4. I zap zone kept the zap zone Fitbit zap zone app open and manual synced the Charge 4 (in zap zone the zap zone app) as often as could while on the charger to get it zap zone to show the "Update Available" in zap zone the app on the phone, zap zone so if you are impatient like I am you could give it a zap zone try.Well that zap zone about wraps up zap zone my review of the Fitbit Charge zap zone 4 zap zone SE. zap zone I hope this review helps zap zone others out there. I zap zone will update zap zone the review as I use the Charge 4 zap zone more and will adjust the ratings up zap zone or down as needed.Note: I was not given this product to evaluate. I paid zap zone for it with my own money so my zap zone review zap zone is not bias in anyway.Updated zap zone March 9th 2021, I can zap zone see why everyone is zap zone leaving zap zone Fitbit and heading zap zone to anyone else but Fitbit... they have very bad tech support, firmware updates take zap zone forever to roll out, and to this date they have not turned zap zone on features that they advertise on their very own website. Shame really as I really like the Charge 4 zap zone but without support zap zone and zap zone timely updates to be it is zap zone not much use.Update May 13th, They finally got zap zone two new firmware updates rolled zap zone out and now nightly SP02 zap zone average zap zone and nightly skin temp zap zone variables zap zone are working on the C4. Unfortunately there is zap zone not many other choices zap zone out there in the world at this moment zap zone that has all the feature in such a nice zap zone small form factor. Believe me I zap zone wish there zap zone was zap zone as Fitbit (Now Google owned) has a lot to be zap zone desired zap zone as far as zap zone support of their products. So if zap zone you are looking zap zone for zap zone something NOW, zap zone then yes the C4 is the way to go unless you can wear something zap zone bigger on your wrist to bed at night. Let all zap zone hope that zap zone new wearable tech from other companies zap zone get released in the next year to zap zone two so that zap zone we have better choices to buy. I have zap zone raised zap zone the zap zone star rating to zap zone 2.5 (they zap zone only let zap zone you choose 2 zap zone or 3 so subtract 1/2 star from what is zap zone showing) zap zone :-)Use 24/7 heart zap zone rate to zap zone track resting heart rate & better zap zone measure calorie burn.

Buyer's experience:


      1: So this is my 3rd smart wearable device I have owned. I have had the original Moto 360 and I currently have the very old (in electronic years) Huawei watch. I will start off by saying that this Fitbit Charge 4 is way more comfortable than the previous two device. Once on your wrist you will forget that it is there except when it buzzes on your wrist for notifications. Speaking of notifications, they work very nicely without being over bearing. You can choose and select from which apps you want to get notifications on, for example all I care about is notifications from WhatsApp, Messenger and my Emails so that is all I have it set to.

I walk 5 days a weeks and workout 3 days a week and the Charge 4 automatically tracks my walks perfectly. As for my workouts it doesn't seem to know when I am doing pushups or pullups and of course it will not pick up the fact I am doing planks but that is ok as I doubt I am burning a lot of calories from my 3 day a week workouts as it is more for muscle toning and trying to keep a flat stomach in my old age.Sleep tracking on the Charge 4 is very nice!

This tracker has a SP02 sensor so in the morning I can check to see how many times my blood oxygen dropped low during the night and so far it has only been a couple times over the 17 days since it has started tracking my sleep. So that makes me feel a bit better knowing I really do not have a Sleep Apnea problem. It would be nice if Charge 4 gave you more detailed blood oxygen information, like percentages during the night, but that might something to due with the fact that this is not a medical grade device and they do not want people thinking that or they don't want to have to go through the process of getting certification for it which would cost a lot and effect the cost of the device.

Mine took 20 hours to finally say there was an update available. I have read it can take two days. So be patient. I know that this sucks but I think they do it that way as to not drain the battery on the Charge 4. I kept the Fitbit app open and manual synced the Charge 4 (in the app) as often as could while on the charger to get it to show the "Update Available" in the app on the phone, so if you are impatient like I am you could give it a try.Well that about wraps up my review of the Fitbit Charge 4 SE. I hope this review helps others out there. I will update the review as I use the Charge 4 more and will adjust the ratings up or down as needed.Note: I was not given this product to evaluate. I paid for it with my own money so my review is not bias in anyway.Updated March 9th 2021, I can see why everyone is leaving Fitbit and heading to anyone else but Fitbit... they have very bad tech support, firmware updates take forever to roll out, and to this date they have not turned on features that they advertise on their very own website. Shame really as I really like the Charge 4 but without support and timely updates to be it is not much use.Update May 13th, They finally got two new firmware updates rolled out and now nightly SP02 average and nightly skin temp variables are working on the C4. Unfortunately there is not many other choices out there in the world at this moment that has all the feature in such a nice small form factor. Believe me I wish there was as Fitbit (Now Google owned) has a lot to be desired as far as support of their products. So if you are looking for something NOW, then yes the C4 is the way to go unless you can wear something bigger on your wrist to bed at night. Let all hope that new wearable tech from other companies get released in the next year to two so that we have better choices to buy. I have raised the star rating to 2.5 (they only let you choose 2 or 3 so subtract 1/2 star from what is showing) :-)


      2: 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 beenBattery: 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 down2) Moving the watch higher on my arm and tightening it. My watch tended to slip around more the further it was from my wrist3) 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
