The purpose of this research study is to test the feasibility, acceptability, and preliminary effectiveness of the use of a mobile pharmacist-led intervention that incorporates home BP monitoring and medication reminders with patients recruited from a primary care setting, as well as identify challenges and potential solutions to broader implementation of a mobile pharmacist-led home-based BP monitoring intervention in primary care clinics through key stakeholder interviews.

Inclusion Criteria:

• Have a smart phone compatible with mobile intervention
• Have been previously diagnosed with hypertension
• Have uncontrolled hypertension (systolic blood pressure > 140 and/or diastolic blood pressure > 90 on repeat measurement)
• Be under the care of a primary care physician at the recruitment clinic
• Be taking at least one antihypertensive medication
• Be English speaking

Exclusion Criteria:

• Patients under the care of a clinical pharmacist for hypertension management, or under the care of a cardiologist
• Pregnant patients and anyone with the following unrelated, but serious medical conditions will also be excluded, as they may make blood pressure control difficult or necessitate frequent hospitalization: previous diagnosis of resistant hypertension; steroid dependent asthma or emphysema; cirrhosis or hepatic failure; stage C or D chronic heart failure; stage IV or V chronic kidney disease; and cancer (terminal or undergoing active chemotherapeutic or radiation therapy)
• Patients with other serious medical conditions (e.g., stroke, dementia) that may affect their ability to self-monitor blood pressure
