First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a mobile app called Collabree to see if it helps people over 50 with high blood pressure take their medication more regularly. 144 participants used the app for 90 days and were followed for another 90 days. The app sent reminders and used behavioral tricks to encourage adherence. Researchers measured pill counts and self-reports to see if the app made a difference.
