Current medication adherence interventions are minimally effective, which results in higher rates of morbidity and mortality for 45 million US adults who have hypertension and low adherence. This feasibility randomized controlled trial seeks to understand the efficacy of reminders and monitoring in the form of a mobile phone application vs usual care on medication adherence as well as the feasibility of the intervention and study procedures. This study will compare participants who use a mobile phone app that notifies them when to take their medications (intervention group) to participants who do not get assigned the app (control group) for 30 days. Medication adherence will be monitored using a Medication Event Monitoring System (MEMS) cap. Both groups will also receive the usual care, which will include giving participants a pamphlet about taking their medications. The long-term goal of this work is to improve antihypertensive medication adherence and to decrease morbidity and mortality. The objective of this application is to test the efficacy of the app based reminders and feedback. The hypothesis driving this research is that the intervention will be more effective than the usual care. The specific aims are as follows:

This study will compare participants who use a mobile phone app that notifies them when to take their medications (intervention group) to participants who do not get assigned the app (control group) for 30 days. Participants will receive an electronic monitoring cap (i.e. a Medication Event Monitoring System (MEMS) cap) to monitor when they take their antihypertensive medications while they are in the study. Both groups will also receive the usual care, which will include giving participants a pamphlet about taking their medications. The long-term goal of this work is to improve antihypertensive medication adherence and to decrease morbidity and mortality. The objective of this application is to test the efficacy of the app based reminders and feedback. The hypothesis driving this research is that the intervention will be more effective than the usual care. The specific aims are as follows: Aim 1. Compare the efficacy of the app based reminders and feedback with usual care for the primary outcome of medication adherence in 40 adults with hypertension and low adherence. Aim 2. Conduct a robust process evaluation to guide intervention improvements, dissemination, and implementation in a diverse sample. The hypothesis will be tested for two specific aims in 40 adults (20 control, 20 intervention) with hypertension and low adherence. For these aims, the study will be conducted as a phase II single-blind, parallel-group, randomized controlled trial with diverse adults with hypertension over 30 days. Participants will answer surveys about their demographics, knowledge about hypertension, and their medication adherence. They will then be randomized and either be given the standard of care or standard of care plus the intervention (app-based reminders and feedback). The intervention includes a brief training session on downloading and using the medication reminder app. Across arms, Participants will track their medication adherence for 30 days using the MEMS cap. After the 30 days, participants will take surveys about their adherence and knowledge about hypertension and have a brief exit interview with a member of the research team to talk about their experience and debrief them about the study.

If the participant is randomized to the intervention group, they will: 1. receive a brief education session and be handed a flyer about the importance of medication adherence. 2. get training on how to use the medication reminder app and participant will be given a user guide on how to use the app 3. demonstrate their understanding on an iPad using the teach back method 4. install and set up the medication reminder app on their phone 5. receive a MEMS cap and be given instructions on how to use it with their blood pressure medication. Study team members will use a participant ID to log into the MEMS cap application; no identifiable information will be entered.

Medication Event Monitoring System (MEMS) Cap
The Medication Event Monitoring System (MEMS) measures medication adherence over 30 days at home. In this system, an electronic cap will be placed on a bottle assigned to the participant's antihypertensive medication and records each time the medication bottle is opened. All participants will use the electronic monitoring for one antihypertensive medication taken daily.
Time frame: 30 days
Exit interview
In the exit interview, participants will be asked qualitative questions about their experiences in the study and using the MEMS cap and medication reminder app. This will support a robust process evaluation to guide intervention improvements, dissemination, and implementation in a diverse sample.
Time frame: 30 days
