The proposed study will address a critical knowledge gap: there are no evidence-based smartphone apps for reducing young adult drinking. The purpose of the study is to test alcohol-related smartphone applications designed to provide assistance during actual drinking situations to help young adults reduce their drinking. It is the researchers hypothesis that participants will self-administer less alcohol when using the experimental app with feedback.

After participants blow their first positive BrAC, they will be allowed to reschedule and participate at another time, however if they blow a second positive BrAC, they will be excluded from this study and offered referrals for alcohol treatment. - Have positive urine screen results at the in-person screening or on the day of an alcohol drinking session for opiates, cocaine, phencyclidine, amphetamines, methamphetamine, barbiturates, methadone or benzodiazepines. - Meet criteria for current nicotine dependence or dependence on any other drug, excluding alcohol. - Report current use of psychotropic drugs including anxiolytics and antidepressants. - Have received a prescription for any psychotropic drug in the 30 days prior to study enrollment - Be psychotic or otherwise severely psychiatrically disabled - Report a history of a medical condition that would contraindicate the consumption of alcohol (e.g., liver disease, cardiac abnormality, pancreatitis, diabetes, neurological problems, and gastrointestinal disorders). - Have a history of clinically significant withdrawal from alcohol, defined as any one of the following: a) a lifetime history of seizures, delirium, or hallucinations during alcohol withdrawal; b) a Clinical Institute Withdrawal Assessment scale (CIWA-Ar, Sullivan et al., 1989) score > 8; c) a report of drinking to avoid withdrawal symptoms in the past 12 months; or d) a lifetime history of medical treatment for withdrawal. - A woman who is pregnant, nursing, or refuses to use a reliable method of birth control. - Report disliking vodka or vodka mixed drinks.
