This work presents a clinical case, diagnosed with anxiety – panic disorder. The client is under a process of psychotherapy, more precisely cognitive narrative therapy. It’s an approach that deals with narrative writing exercises that the client has to perform at home, after the therapy sessions. We discuss how it could be quite useful having a narrative mobile app to write them down. We present here these exercises and discuss how a new app could really engage and motivate even more the therapeutic change of clients doing cognitive narrative therapy. This is an interesting way to match technology and psychotherapy. To clarify what is cognitive narrative therapy and, how an app can be of such use to the work of a narrative therapist, is the main goal of this work. Cognitive narrative therapy advocates that, the more the person is aware of his five senses, his feelings and thoughts and how he can put them into narrative words and metaphors, the more his mind is free to live mentally healthy.
