But will that effect health? Injecting infra red and green light in 24/7 heart rate monitors can cause health issues?

Can you please explain abt measuring BP? is it really possible?

[codmxdude]

How they know how much steps I ran or walked..
Also how it knows how much floors I climbed today. ECG, stress, and blood pressure ?

[nguyenconghuy]

Is this accurate or near accurate, is there any factor can affect measurements, how accurate it is compare to blood test and cardiograph?

[sTOPzTARINGAlright]

All this sensors is it risky eg long term usage will result in major deseases or is it safe

[itzskyliter]

So if a watch is Using Green light to Detect our SPO2 too does that mean it's inaccurate or fake?
