The study aimed to examine the effectiveness of an intervention using a smartphone application for psychological self-help among adolescents at risk of suicidal behavior. Over 12 weeks, a proprietary program was implemented for children aged 13–15. The questionnaire results of the experimental and control groups were compared using the independent samples t-test. The research results underscore the practical significance of employing self-help psychological apps as an additional tool in working with youth at risk of suicidal behavior. Integrating such technologies into adolescent interventions can contribute to enhancing the effectiveness of psychological support and preventing negative mental health consequences.
