Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing a mobile phone app called uMAT-R that's designed to support people in recovery from opioid and stimulant use. The study is comparing two versions of the app: one with extra community support added to it. If you're eligible, you'd be part of research that could help improve recovery tools for people like you.
Many people struggling with opioid and stimulant use also face depression and anxiety, and they need more accessible ways to get support. This trial is testing whether a mobile phone app—something people already use every day—can be an effective way to help people stay on their recovery path and manage their mental health at the same time.

You would use the mobile app as part of your regular recovery support. Depending on which group you're assigned to, you'd either use the standard version of the app or the version with extra community engagement support built in. The study team would track how you're doing and how you're using the app to understand whether it helps with recovery and mental health.
