Does anyone know if wearable BP monitoring can actually be accurate? I have a relative who is unwell and this could be useful for them but, equally, would be very unhelpful with inaccurate data.

Are there better alternatives?

It doesn't give you a live BP reading. It just does some sort of fuzzy inference using data over time kind of like how the Whoop tries to estimate your BP in the morning based on overnight data.

The Apple Watch just notifies you when it thinks you might have high BP and you have to use a cuff to see if it's correct. So, we're still some ways away from passive BP.
