Summary

This study tested whether a smartphone app called LowSalt4Life can help people with high blood pressure reduce their sodium intake and improve blood pressure. The app provides tips and reminders to eat less salt. 410 participants with high blood pressure used the app, and researchers measured changes in blood pressure and salt intake. The goal is to see if a simple app can make a real difference in managing hypertension.
