Most individuals whose alcohol problems are not severe, particularly college students and young adults, do not seek treatment. Several studies have shown that many people with alcohol problems can successfully change their drinking with minimal help. Now an app, iSelfChange™, has been developed for Smartphones. This evidence-based smartphone application was designed to promote a healthier lifestyle by allowing people to better understand their drinking behavior and moderate their alcohol intake. Smokers can also track their cigarette use. The iSelfChange™ app is available 24/7, is confidential, innovative, free, and provides a non-stigmatizing way of helping people change their drinking without entering treatment. The app can be downloaded for free at the iTunes and Google Play stores by searching for iSelfChange™ or clicking on the following links.
