Every day, an average of sixteen Poles take their own lives, unable to bear the suffering caused by depression. It is a disease that affects over 1.5 million Poles. At Ati Labs, we deal with the use of modern technologies in the field of mental health and we believe that it is possible to develop a mobile application that supports people struggling with symptoms of depression. We are implementing the SIMON project: a computer therapy system for depression. The success of the project will make SIMON a professional psychological support, based on the techniques of cognitive-behavioral psychotherapy, available to anyone, in a few clicks, on their own phone.
