Testing a smartphone app to help control high blood pressure

This trial is testing whether a smartphone app called ESH CARE can help people with high blood pressure get better control of their condition. The app lets you send home blood pressure measurements to a clinic, where doctors can monitor your progress and adjust treatment as needed. The study will compare this new approach to standard care (regular clinic visits alone) over one year.

Many people with high blood pressure struggle to keep it under control, even with medication. This trial wants to see if giving patients a way to track their blood pressure at home using a smartphone app—and sharing those readings with their doctors between visits—helps bring their blood pressure down better than regular clinic visits alone.
