PTSD Coach was designed for veterans and military service members who have--or might have--post-traumatic stress disorder. The app educates users about PTSD and provides self-assessment tools. In addition to finding support, users can access tools for managing daily stress, practicing relaxation skills, and learning common self-help strategies. The highly rated app--available for iPhone, iPad, and Android devices--can be customized, so those suffering from PTSD can use their own contacts, photos, and music to get a more personalized experience. PTSD Coach, which was created by the Department of Veterans Affairs' National Center for PTSD in collaboration with Department of Defense's National Center for Telehealth and Technology, is intended both for people who are in treatment and those who aren't.
