Testing the Effectiveness of a Novel Intervention to Improve Medication Adherence in Stroke Survivors

The goal of this study is to test if Savvy, a multimodal intervention (consisting of psychological exercises, a weekly pill organizer, and a text message reminder system) can improve medication adherence in stroke survivors. The main questions it aims to answer are: * Can the Savvy tool improve medication adherence in stroke survivors compared to usual care? * Does the use of the Savvy tool lead to better blood pressure control after a stroke? The investigators will compare the use of the Savvy intervention to a control group that receives usual care, including a package of educational materials. The study consists of the following components: * Participants will receive the Savvy intervention or usual care. The intervention package consists of short psychological exercises over the phone, a weekly medication organizer to support daily medication intake, and text message reminders to take medication and refill the medication box. Participants in the control group will receive usual care, including educational materials about the importance of blood pressure and medication. * All participants will receive a free home blood pressure monitor and will be requested to measure their blood pressure at certain time points during the study. * Participants will be enrolled in the study for 6 months and will have virtual follow-up calls at 3 and 6 months.
