My new phone has an App which says it can take Heart Rate, Blood Pressure and O2 levels by putting a finger on one of the cameras.

Heart Rate, yes, although it does not agree with my Omron arm monitor or my counting per minute. But I was led to believe that Blood Pressure needs an artery to be compressed/restricted, and then slowly released, as a sphygnamometer does. And as for measuring O2 in the blood...HOW? Please.

I have similar on my smart watch, whats important to remember is to use these things as "indicators" and nothing more, they are not medical devices and shouldnt be regarded as such. If you want to understand how they actually work, why not ask chatgpt, bound to get the gist from that.

 

Heart rate on my smart watch too, fairly accurate below 100bpm, nonsense above that.

I use it to record all my cycling trips on Strava, impressed by the GPS in it, also nice to be able to read emails, notifications and take phone calls without needing to get my phone out.

I wonder if it is legal, and safe, to read emails, notifications and take calls on your watch while driving or cycling as opposed to your phone.

I am sure there is somewhere a fine print that the data is not accurate and should not be relied on for medical reasons.

Some time ago I bought a blood pressure device. Before I did that, I looked at comparisons from test organizations. Some devices were not as good as other.

I bought a good device, with app for records, to have accurate results recorded.

IMHO anything else is just a gimmick. 

 

The O2 is always measured optically. I once read an article about it how that is done. It made sense.

Sorry, no link.

No, may lead to hitting a car, hospitalization, and then claiming attempted murder by the driver.

It's surprisingly not bad for what it is. Useful and just an indication. If a number is wildly out of line, then you know to check it on a more reliable device.

Surprisingly not bad......it's useless, as several other similar Apps. Said my BP was 181/ 88 this morning with a beat of 76. Omron said 124/74/50 as usual. So now I shall use the 'more reliable device' all the time

About as much use as indication when it says that you are driving at 90 kph when really you are doing 120.

Did you try it several times, making sure to get good contact? Maybe "iPhone syndrome" like "white coat syndrome?" 😉 

 

Try the smart watch.

Yes, tried it several times on other mornings. Still same inaccurate results. I have uninstalled it from my Android.
