First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a mobile app called Collabree could help people with high blood pressure take their medication more regularly. 181 adults in Switzerland who took at least 4 blood pressure pills daily participated. They were randomly assigned to use the app or receive standard care, and their medication taking was tracked for 90 days. The goal was to see if the app improved adherence and lowered blood pressure.

Active substance
Collabree mobile phone application
What this could lead to
If it works, this could offer a simple, app-based way to help people with high blood pressure stick to their medication routine and improve blood pressure control.
What could go wrong
This is a small, completed study with 181 participants, so results may not apply to everyone. The app's effectiveness depends on consistent smartphone use, and it does not replace standard medical care.
