I’m primarily talking about stuff like step counters, but also health apps measuring your heart rate, how many stairs you take, the length of your steps, and so on. I’m honest when you tell me to explain it to me like I’m five years old, this one boggles my mind.
Samsung phones used to be able to measure heart rate along with blood oxygenation. Not sure when they stopped, but I know one of my old galaxy’s had it, either the 5 or 8.
I think it had to do with how the cameras and lights were oriented. I missed that one too. Pretty damn accurate.
Something like that, yeah. Didn’t personally have an actual practical use for it, but it was certainly a nice thing to have.
