NCT ID NCT05856955
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This pilot trial is testing a smartphone app that acts like a personal coach to help adults with uncontrolled high blood pressure improve their self-care. The app provides education and interactive coaching to encourage medication adherence and healthy habits. The study will enroll 40 adults from disadvantaged neighborhoods to see if the app is easy to use and engaging. The goal is to gather information for a larger future study.
