Phone app pays you to take your blood pressure meds – but does it work?
NCT ID NCT06876233
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a smartphone app that offers small cash rewards for daily pill photos can help people with high blood pressure stick to their medication. Six hundred participants will either get the app with rewards, the app plus a personal action plan, or standard care. The goal is to see if these simple tools improve medication habits, lower blood pressure, and reduce healthcare costs over two years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Wellth app (behavioral intervention with daily incentives and action planning)
- What this could lead to
- If successful, this could provide a simple, scalable way to help millions of people stick to their blood pressure medication, reducing heart attacks and strokes.
- What could go wrong
- This is a behavioral study, not a drug trial. Results depend on participants' willingness to use the app daily, and long-term adherence after incentives stop is uncertain.
