Signal Ring gives blood pressure readings, not just alerts like Apple Watch

The Signal Ring by Vital Signals offers continuous blood pressure monitoring, providing actual readings rather than simple alerts. Unlike Apple Watch models that notify users of possible hypertension or other fitness devices requiring regular calibration with traditional cuff monitors, this ring claims to deliver full measurements without calibration. Backed by a trial involving thousands of people, the algorithmic technology aims to reshape how individuals manage hypertension and various cardiac conditions through a wearable ring format.
