Hi:
I am 66+ and a Wyze user for some time. Having had two life changing events in the past two months, my stress levels are a bit too high. The issue I have is that the Wyzeband is showing a BP rate of between 41 and 43 (average is 65/68) and this caused an additional stress to my personal health. While I know that the Wyzeband is a low cost device, it would have been good if Wyze had declared upfront that the BP rates are not very accurate. I had to go to my doctor, get a stress test and get a 24x monitoring device. I will match the Wyzeband with the more accurate device and see if I do indeed have bracharydia (low BP rate).

I am a bit older and when I first saw the 40’s showing up I double checked with a wrist BP. Never could repeat on the BP and I just went for a physical after 2nd Moderna shot + 2 weeks. These numbers only appear on the tracker once or twice a day. Normally about 80bpm and up to 130bpm under heavy activity. Mentioned it to the doctor who was not concerned. He wasn’t a fan of device accuracy. I wish I had a better answer, but I agree that it was very upsetting the first time it appeared. The only answer is getting fitted for a heart monitor for a week or so. It was not a pleasant experience that I would like to repeat but it would at least give you peace of mind. I also have an Amazfit watch (2nd generation) that also pops up with an occasional 40’s, but two inaccurate devices does not make for an accurate reading.
Thank you very much Joel for the detailed reply. I am relieved that you have also had similar experiences with the Wyzeband and not my imagination. With the Covid issues, access to your physicians for basic care is now a major issue. My Kaiser physician usually wants all communication via email (using the Kaiser’s badly designed website) and he responded with a stress test and the monitor.
My point with Wyze is to put a warning that the Wyze band has inaccuracies with measurement and not to rely on it. While I do appreciate that for $20, you cannot expect great accuracy and this not a gripe against Wyze. But the warning goes a long way to reassure senior citizens like me not to get unduly worried.

PS: What other Wyze devices do you use ?
I have checked the bpm heart rate on my new Wyze Watch against the older Wyze Band and a finger pulse meter. In the past I have found the Band to be consistent with the finger meter. I also have a portable display unit that measures a single channel. I found several problems (or suggestions) for the Watch.
First it is completely inaccurate in the higher ranges. My test was with my Band and Watch both on my left wrist. I was repeatedly carrying “stuff” down from a 3rd floor for about 45 minutes. I did not have the finger meter so I could only compare the two Wyze products. The Band would read in the range of 120bpm while the Watch would be down in the 70’s or 80’s. Since I had good luck with Band against my other methods, I assume it was reading accurately. The Watch during this “exercise” period never got up to 100. I know and watch my pulse rate since I do have a fully blocked heart artery on one side and two stents on the other side of my heart. The Watch is only accurate when resting.
Second it takes a longer time than either device to get a reading. Many times the reading is knowingly low so I have to re tap the icon to get it to repeat the reading. Usually on the 2nd or 3rd tap it matches a low reading eg. one in the 80’s.
Third, the Band holds the reading beyond the display timeout. So for a few reading over a period, I can just flip my wrist and see the reading. The Watch with a short display time, requires me to flip (or press button) then swipe, then tap the heart icon. It then starts over taking its time for a reading. Not a very ergonomically designed function.
So as far as the heart function, I would suggest you use the algorithms and timings from the Band and update the firmware to the Watch.
I am now wearing the Wyze Watch (47) and my low BP’s are in the mid to high 50’s. 60’s are a good neighborhood so a ± area in the 50’s is not as alarming as the 40’s. The blood oxygen numbers (high 90’s) are excellent and pretty much offset any weird BP numbers.
