By Meridian48 News Desk · Summarised from 9to5Mac ·

The upcoming Signal Ring promises to deliver accurate blood pressure measurements without requiring calibration from a traditional cuff monitor.

Meridian48 take
If validated independently, this could disrupt the wearable health market, but claims of calibration-free accuracy demand rigorous third-party verification.
