Brief Summary
This randomized controlled trial will assess the efficacy and scalability of a blood pressure technology system intervention. The investigators will enroll 224 older adults with hypertension to identify those who are nonadherent for one hypertension medication. The participants will be randomized to one of two groups (112 per group) to use the blood pressure system for 6-months. Both groups receive information about high blood pressure and medications. One group will also receive strategies that can be used to take medications and manage blood pressure. Both groups will complete a mid-assessment at 3-months and a post-assessment at 6-months.

Outcome Measures
Primary Outcomes (1)
adherence
Change in adherence (both objective and subjective) after 6 months of M system engagement versus E system use. Objective adherence is measured by Aardex Medication Event Monitoring System (MEMS). Subjective adherence is measured by the five-item Medication Adherence Report Scale (MARS-5). MARS-5 total score ranges between 5 and 25, with higher scores indicating better adherence.

Study Arms (2)
Blood Pressure Technology System M
OTHERThese participants will receive information about high blood pressure, medications and strategies that can be used to take medications and manage blood pressure. They will complete a mid-assessment at 3-months and a post-assessment at 6-months.
Blood Pressure Technology System E
OTHERThese participants receive information about high blood pressure and medications. They will complete a mid-assessment at 3-months and a post-assessment at 6-months.
Interventions
Participants will be provided the blood pressure technology system E. The study staff will teach the participants how to use the system on their personal cell phones with instruction guides. Participants will be asked to use the system for 6-months.
