The new, still nameless device is supposed to focus solely on helping people recognize high blood pressure. It’s based on a technology similar to heart rate meters using PPG, or Photoplethysmography. The device shines pulses of light on the finger’s skin to measure your blood flow. Using algorithms, AI, and a ton of data from a test group of over 7,000 people, a measurement is taken. Results are displayed both on the device itself and your phone via Bluetooth.
What’s new here is that the device doesn’t have to be calibrated with a regular cuff first. It works right out of the box, though presumably, you need to enter some physical data before (age, weight, gender, and height are needed to determine the blood pressure).
Yes it's not a 24/7 wearable, but I suppose on the other hand it is portable, easy to use, does not require regular calibration (like Samsung's Galaxy Watch 5), and can be used with most Android phones.
An interesting idea may be to use this to calibre the Galaxy Watch 5, weekly or daily, and then let the watch do the 24/7 monitoring.
But we'll need to wait for its US FDA approval, and some real world test reviews, before buying it.
