Study Overview: This study is comparing two ways to manage blood pressure: using new technology versus usual care. It will help see which method works best in different groups of people. The study involves three groups (called cohorts) with different recruitment methods to ensure diversity. Key Terms: - **Cohort**: A group of people participating in the study. - **Anti-HTN meds**: Medications to lower high blood pressure (hypertension). - **SBP**: Systolic Blood Pressure, the top number in a blood pressure reading. Participation Details:

• The study takes place at Stanford and Morehouse School of Medicine.
• Participants need to be 30-90 years old, have a smartphone, and speak English or Spanish.
• Excludes people with certain medical conditions like severe heart or kidney issues.

How It Works: Participants will be randomly divided into groups to receive either the usual care or technology-based care to manage their blood pressure. The study will measure how well each method works, focusing on diversity in participation and engagement.
