Hi Rob, you should make a video on which is the most accurate fitness tracker. This would be more beneficial in helping people choose a fitness tracker. Your videos are amazingly well done though. Thank yoU!

Agreed, but sometimes there is value in subjective and biased analyses as well.

I've watched a lot of your videos - I f****ing love them! Do you have a ranking of all the devices you've tested? That video would be aaaawwweeesssooommmee!

Wow, you really raise the bar on device reviews in general. Thank you for taking the time to test and review these!

your videos are so specific and scientific,I love that

Thanks, I think you should make a top of the options of sleep trackers less than 200 dollars, and a top greater than that value

Man... the amount of effort you put into this, much better than the average "review" that just states superficial qualities, I really respect you for providing non-biased reliable reviews.

As always, excellent, quality content! You're an incredibly underrated creator! Thanks!!!

Your level of details in videos is amazing, keep up the good work.

Bought the Fitbit charge 5 because of this channel. Sleep tracking is the most important to me. Rob testing out wearables in such a scientific approach really helped a lot in my decision. This channel deserves more subs!

How is it now? The product reviews I see all over the web is holding me back on getting one but I wanted it so bad

Hi Rob, I was wondering if you have ever thought about doing a series comparison series? For example, I would be interested to see how the charge 5 compares to previous iterations of the model. Has the sensor accuracy improved? Or have the sensors remained the same with updates to the software?

Your videos are so awesome. Nothing compares to your scientific approach in helping to decide which device to buy. Comfort, charge time, waterproof and things like that are helpful, too. But so far, I find no other videos comparing the actual accuracy scientifically like you do ! Awesome!

Really love the videos. This is what is needed and really much better than most of the other reviews that just tell you what is on the spec sheet which is basically pointless.

Awesome video. I really appreciate you taking your time and effort into scientific testing of such devices which claim to be very precise.

The one I've been waiting for. Good man! 👍💪👏

Impressive and thorough testing, thanks so much. Your work confirmed some of my anecdotal observations/suspicions (mainly missing heart rate peaks and somewhat overcounting steps) , but overall, I'm happy with the Charge 5.

Wow! Gps accuracy was sth that made your contents complete. You are awesome honestly.

Hands up for this dude for such a very detailed review.. Kudos! I admire u so much.

I recently bought a Charge 5 and get on well with it. I am not looking for massive accuracy and won't lose sleep if my step count is a couple of hundred off accurate over the space of a day... I bought it to help with general awareness of my activity and just so I can see in relative terms, what I am doing and how much I am moving around and it does it well. Great to see someone having taken the time to do all this research, very interesting to see!

Such a wonderful review. Thank you, Rob! I'd love a review about Garmin forerunner 45! ❤️

Wow, thank you! That is too kind! Have a great day😊

Thank you for the review. I would like to see both from reference methods how good fit for the sleep analysis. Due to the accuracy of the device, there would usually be slight deviations.

Thank you for your review’s! I have the Fitbit 4. I appreciate the heart rate review about its highs and lows, it freaks me out sometimes at night when it shows my heart rate in the low 40’s then it would spike to 120. My husband told me not to freak because he doesn’t thinks it’s accurate. So thank you again for confirming that for me. Maybe I’ll sleep better now 😉😊

You did an excellent review. I'm older, 65, and working on losing weight. I am interested in which Fitbit to get to best track steps & other exercise. I'm less interested in sleep tracking bc I figure it is what it is & will likely improve as I lose & get more exercise.

Another terrific video, thanks for all the hard work you put into each one. I look forward to the update as I am very interested in whether this (or any other band/watch) would be accurate at recording ECG, especially as from both your channel and personal experience I know that these wearables are pretty hopeless at SPO2 due to the restricted way they have to work as light can't be detected through the wrist, instead having to use reflected light. The fact Fitbit was forced to release this without one of its main features makes me concerned that ECG might be unreliable too. BTW, having to pay Fitbit a monthly fee to access the full sleep tracking data is outrageous, but at least ECG is not behind a paywall.

@stephw1363

Yes! To hold back data that doesnt even belong to them is kind of lawsuit material. I hope they get some pressure for doing this.

Interesting and informative video, loved the scientific approach. I just wanted to make you aware of a slight limitation to your heart rate testing if you were not already aware. ECG monitors calculate heart rate based on the electrical activity it senses and I think most fitness watches and finger probes sense the pulsatile flow of blood. The first small issue is that ECG devices can misidentify ECG distortion/artefact as a heart rate but this is well known and difficult to avoid. The other slight issue are ventricular ectopic beats, which are extra beats from the bottom chambers of your heart. Ectopics are seen in normal healthy hearts but can be associated with various conditions. It's worth noting that ventricular ectopics produce a very weak or no pulse (because the lower chambers have not been able to fill with blood) which usually does not produce a palpable pulse in the wrist. This means the ECG monitor counts the ectopic as a beat which the watch or probe is unable to sense and therefore does not count. As a side note I have looked after cardiac patients in "ventricular bigeminy" (every other beat is an ectopic) and the ECG monitor reads heart rate 84 bpm (for example) and the probe on the finger reads the heart rate as 42 bpm (this is an extreme example of this mismatch). Overall these are generally just small limitations but are dependent on how many ectopics you have and how much artefact there is in the ECG.

The best the best & the best scientific reviews I’ve ever seen on the planet about a gadget 👏👏👏👏👏👏👏👏👍👍👍👍👍👍👍👍

Thanks Babak!!

I've found that if you change your setting on what wrist you have your fitbit on in the fitbit app and put it on dominant either if you have it on right or left it will help to prevent overcounting steps. "For wrist-based devices, it's important to specify whether you wear the device on your dominant or non-dominant wrist during setup: The dominant wrist setting decreases the sensitivity of step counting and should reduce any over counting of steps when your body is not moving. Your dominant hand is the one you use for writing and eating. The non-dominant wrist setting increases the sensitivity of step counting and should reduce any under counting of steps." This is from fitbit site and I choose the dominant setting even though I use it on my non dominant hand because I use both hands pretty much every day.

Having worn my Charge 5 for just aweek or so now, I find it very optimistic about step counts over the whole day. Probably not too bad for the periods when I'm actually walking. Compared with the step counter on my phone (which I'm inclined to believe) Monday Fitbit 19164 steps 14.38km / Phone 14554 steps 10.35km Tuesday 22921 17.16km / 15683 11.62km Wednesday 21608 16.21km / 16832 12.06km Thursday 19349 14.51km / 14787 10.82km I haven't yet worked out exactly where it is overcounting so badly. For now, I'll rely on the phone for steps and distance, and use the fitbit for everything else that it does. (Fitbit on my right/dominant arm and set accordingly i'n the app.)

Been wondering about Fitbit sleep detection for months. Thanks!

I am looking to buy charge 5. This is by far the most comprehensive analysis of the device out there.

Excellent review. I really appreciate the time you put into giving your viewers in-depth information. The inaccuracy of the heart rate bmp and the inconsistency made my decision to return the Fitbit Charge 5. I could of accepted it being off 10 bmp but 35 to 47 bmp either to low or to high was unacceptable. It’s unfortunate because I liked all other things about the Fitbit.

I haven't bought the series 8 yet but your video showed exactly where my interest in the Apple Watch was, namely fitness and sleep. I now feel justified in spending my money on this watch. Thank you.

Keep up the great work!

Great job, I was waiting for it. But I didn't expect it so soon. I'm already looking forward to the sequel. I have a Fitbit charge 4. I bought a better metal magnetic bracelet for it, it holds better and thanks to that the measurements are also a bit more accurate. Most silicone bracelets do not last longer than 6 months and are less comfortable to wear. I will not buy a new one at the moment, but I would do it in about a year. Thanks for testing ROB!

you are totally right, I don't see people saying that much. I have always gotten a 3rd party metal magnetic snap wrist band when available for my fitbit.

Would be great to see a similar review done with the Pixel Watch - apparently the Heart Rate sensor is better. Keen to see if the performance during weight training improves.

Thank you for the detailed information !

Hi Rob, I’m new to your channel and love the content. I currently own a Fitbit Charge 2 and am thinking of ‘upgrading’ to the Charge 5. I was wondering if you’d consider testing the Charge series and seeing if they’ve improved over time. This would aid anyone using the Fitbit ecosystem to make the best upgrade choice. Regards, Phil, UK 🇬🇧

Hi Rob,. Thanks for your excellent analysis series. In preparation for buying a new fitness tracker, I watched probably 10-12 of your analyses. After consideration of cost vs. accuracy vs. battery life, I got a charge 5 from Amazon. I'm pretty happy with sleep tracking but I notice what seems to be a slow HR response to increased exercise intensity. I have a polar F6 and will compare the F6 and the charge 5 when I get new batteries in the F6. I also note slight overcount in steps against actual count. Overall I am happy with my choice of the C5 thanks to your excellent review. Rick

Update to the review above. After 5 months with the charge 5 and adding an h10 to my arsenal, I've found that the charge 5 has significant lag in picking up an increase in heart rate; around 1-2 minutes. It also lags in picking up a decreasing HR. In between it was fairly close to the h10.

I have a Fitbit Sense and it isn't even close. I have had nothing but problems with it, first one I had wouldn't even turn on and it was fully charged!

Love this. Very scientific. Awesome. I have sleep apnea and now using a specialised mouthgaurd. I will buy a fit bit charge to quantify my sleep.

What a nice review once again, thank you. I wish Fitbit will release a stellar follow up to Fitbit Sense which seems hit and miss and I don't much care for it's Apple watch clone looks and missing physical buttons. Having owned and liked the Ionic which is starting to lose it's battery life.
