Researchers are studying whether HartWay is easy to use and whether using the app for one month may help reduce alcohol-related harm and improve quality of life. The study will also look at drinking patterns and participants’ experiences using the app.

4. Complete the second survey: After one month, complete a second survey, which takes about 20 minutes and also includes a simple at-home urine test.
