    Hi there,

    I want to buy a wearable to measure the basics such as, oxygen, heart rate, atrial fibrillation, sleep, and so on. I'm on Android, so no Apple watch for me.

    I thought the new Google Pixel Watch could be a good candidate, but I see there are several drawbacks: short battery life, it requires a Fitbit subscription for some features, etc.

    After some research I ended up considering Coros Pace 2, but if I'm not mistaken it doesn't measure the oxygen.
    Then there's Fitbit Charge 5, which seems to be still a valid choice in 2022.

    Is there any other good alternative I could take into account?

    I moved this from the General News forum to the Fitness Trackers forum. Another option is the Buyers Guide forum, but let's see what kind of traffic you get here.

    Have you looked into Amazfit? They have a pretty good reputation. https://www.amazfit.com/us/

    Thanks B. Diddy,

    I totally overlooked the Fitness Trackers forum!
    Thanks for moving the thread in the appropriate place, and for the link, I'll check it out.

    The Amazfit looks interesting indeed.

    I'm looking at the GTS 4.
    It doesn't have ECG, though it does use a BioTracker PPG. I'm not clear on whether the ECG are actually useful on wearable or not, it seems it's not accurate. So, I wonder if the BioTracker PPG could be enough.

    The thing is, on top of the other biometric data, I want to keep an eye on my hearth, and even though none of the wearable around are meant to be taken as a professional medical evaluation, I think the hearth rate should still be useful to keep an eye on.

    Hope someone can shed some light.

    Thanks again for the Amazfit link.

    do you want one that you can tap and pay as well with with google pay? Also you need to check whether or not the fitness basics are even activated. For example, samsung watches has the ability for blood pressure and other but not approved for use in the US. It's been that way for years.

    It's worth pointing out that in order to record a true single lead ECG, the user has to touch the crown with their other hand, thus completing an electrical circuit through their body (across both arms, so as to measure the electrical current generated by the heart muscle). From what I understand, the Apple Watch (and other watches) can do this, but when the user is otherwise just wearing the watch without completing that circuit, the Apple Watch relies on reading the pulse via plethysmography (i.e., using the LED light on the back of the watch to figure out when a pulse is happening), and by using a proprietary algorithm, can determine if the heart is in atrial fibrillation (and probably atrial flutter as well, depending on how variable the atrial block is). However, it canNOT determine if the user is having a heart attack, nor is it very useful in determining any other serious arrhythmia.

    Atrial fibrillation/flutter is an important condition to detect, so I'm not discounting the benefit of that function -- but it may be helpful to know that it probably doesn't have much other benefit beyond that.

    Here's an article discussing the issue: https://www.sciencedirect.com/scienc...50173819301495

    That's very interesting, and informative.
    Once again, I thank you B. Diddy for your help, I'll read the article.
    @me just saying
    Good points!

    I'm not too interested in the paying options, but yes on the other basics that need to be available in the U.S.
    I'll make sure to check that part carefully. Thanks!

    The Galaxy Watch 4 is currently $199.99 at Best Buy. It does do heart rate, oxygen, sleep tracking, and I believe it also does ECG. It also does most everything and anything else you might want it for. Might be worth looking into.

    I looked at the Galaxy Watch 4, and despite being a great watch, it has a few downsides for me: the battery life isn't great, it needs full immersion in the Samsung world in terms of apps, registration, and the privacy part doesn't seem too clear.

    After reading articles, and watching some YT videos, I think I'm nailing down my choice to something more like a Garmin Forerunner 245 then a more generic smartwatch. Not that I do any particular workout, running, or hiking activity (those are kind of sporadic for me), but I like the fact that the Garmin is more oriented to the activities in general as opposed to the smartwatch features of say Google, or Apple. Even the fact that it is not touch-screen it's actually a good thing for me. The battery life is really good, about 7 days. Also, the smart trainer, and Garmin connect app look quite solid.
    That said, it doesn't have ECG

    I don't know much about the Garmin watch but Garmin is a good make & it sounds like a great watch even if it's doesn't have ECG. Battery life is going to be stellar. And your are right, the GW4 does not have the greatest battery life. And I'm not sure what limits the GW4 has on a non-samsung phone.

    Definitely give us your real life review of the Garmin if you do decide to get it.
