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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance

What this could lead to
If successful, this app could help people with high blood pressure take their medication more consistently, improving blood pressure control and reducing health risks.
What could go wrong
This is a small, completed study with 144 participants. The app may not work for everyone, and results might not apply to people who don't use smartphones or have different medication routines.
