Samsung makes a step towards measuring blood pressure via a smartwatch, but it's not quite the holy grail

Samsung announced a new line of wearables this week, including a new smartwatch called Galaxy Active. The device claimed to monitor users' blood pressure, which some suggested would put it ahead of its key rival, Apple, as the first big tech player to make such an important breakthrough.
The company said the new feature would come later next month through a research app developed in partnership with UC San Francisco, called My BP Lab. From mid-March, users can download the My BP Lab app via the Google Play Store, which now integrates directly to the Galaxy Watch Active and the Galaxy line of smartphones. The company added in a statement that this would allow people to "monitor blood pressure and keep better track of their physical health every day."
