App attack on high blood pressure: digital tool shows promise
NCT ID NCT06242483
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a smartphone app called Elfie to help people with high blood pressure lower their numbers. 930 adults with uncontrolled high blood pressure used the app alongside their usual care or just usual care alone. The goal was to see if the app could help bring down systolic blood pressure (the top number) more effectively.
