Summary

This study tests a mobile app called DynamiCare, combined with a patient navigator, to help people recently released from jail or prison reduce their use of stimulants like methamphetamine or cocaine. The app uses at-home saliva tests and financial rewards to encourage healthy behaviors. The goal is to see if this approach helps participants start or restart HIV prevention (PrEP) or treatment (ART) and achieve viral suppression. This pilot phase will enroll 40 people to check if the program is feasible and acceptable.

What this could mean

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

Active substance: DynamiCare mobile app (contingency management platform) plus patient navigation
What this could lead to: If this works, it could provide a scalable, mobile way to help people leaving justice settings reduce stimulant use and improve HIV prevention or treatment.
What could go wrong: This is a very small pilot study (40 people) testing feasibility, not effectiveness. The app may not work well in this population, and results may not apply to everyone.
