The Moodpath App offers a screening procedure for depression detection using Internet applications and mobile devices designed to enable users to make an informed medical self-assessment of the presence of symptoms of depression and to use the information obtained for recommendations for further action and support services. Moodpath offers the user interactive texts, videos and audios for support and also offers the possibility to pass on the information gained to doctors and psychotherapists. The services of Moodpath are intended as medical orientation of the user regarding the need for treatment of their mental health and for self-help before and during treatment. The collection and processing of the subjective data of the users and the transmission to doctors and psychotherapists should also form a medical-therapeutic basis in order to actively prepare and support the necessary diagnostics and therapies. The Moodpath application explicitly does not replace a diagnosis of a doctor or a psychological psychotherapist, but can only prepare and support the way to a psychiatric or psychotherapeutic treatment.
