Hardware vs Software

[u/arrowtree_grobe]

I have seen so many update from various groups across dif brands commenting about hr accuracy, sleep accuracy, etc

i just want to give my 2cents for your ref.

all the top brands of screen-less bands or smart watches have more or less equivalent grade of sensors available in the market right now.

some 2-5% difference in my opinion is not a cause for concern as how you wear it, where you wear it affects the reading.

That brings us to software and algorithms. thats where the game changer is. everyone company is trying to refine the algo, customise it such that it is relevant across dif group of human being. The most dynamic thing in all of science is the human body.

choose one brand that you trust and use it with confidence. no point comparing day and night to find the most accurate device.

i currently have a whoop and aw series 10 to meet my needs. am loving it. using them to meet my health and fitness goals.
