Mobile apps can be effective tools that make therapy more accessible, efficient, and portable for those with anxiety disorders, depression, OCD, PTSD, and other related disorders. ADAA provides a list of Mobile apps that are available to the public. When you are trying to select an app for its benefits and ease of use, read the reviews shown by ADAA members. These volunteer reviewers are mental health professionals with degrees in psychology, medicine, social work, and counseling; they are not involved in the development or marketing of mobile apps.
