NCT ID NCT06876233

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a smartphone app that offers small cash rewards for daily pill photos can help people with high blood pressure stick to their medication. Six hundred participants will either get the app with rewards, the app plus a personal action plan, or standard care. The goal is to see if these simple tools improve medication habits, lower blood pressure, and reduce healthcare costs over two years.
