Summary

This study explores whether a smartphone can reliably screen for high blood pressure by analyzing video recorded at your fingertip. About 100 adults will record their blood pressure using both a smartphone and a standard arm cuff, three times each morning and evening for a week. Researchers will compare the two methods to see if the phone can accurately detect hypertension.
