Background/Objectives: In recent decades, new technologies have been progressively integrated into various areas of mental health care. Mobile applications are potentially effective tools that allow psychiatric patients themselves to access self-management resources and tools within the community setting. Mental health nursing plays a key role in enabling patients to take an active role in their care and in promoting activities that foster their involvement and empowerment. The primary aim of this pilot study was to develop the PsyAPP mobile application to support both nurses and individuals with mental illness in managing care and improving health outcomes, and to assess its feasibility within a real-world clinical setting. Methods: A mobile application (PSYAPP) and a complementary web-based nursing management platform were designed and implemented. A total of 20 psychiatric patients enrolled in a partial hospitalization program in Soria (Spain) participated. Participants were assigned to experimental (app users) and control groups. Psychological empowerment, global functioning, and suicide risk were assessed before and after the intervention. Results: Patients who used the application showed significantly greater psychological empowerment (W = 2.04, p ≤ 0.04) compared with the control group. Statistically significant improvements were observed in psychological, social, and occupational functioning. Regarding suicide risk, no statistically significant changes were detected between pre- and post-intervention measurements in either group. Overall, PSYAPP demonstrated feasibility and potential utility as an innovative tool to support mental health care follow-up. Conclusions: This study developed and implemented a mobile application designed to enhance mental health care by supporting both patients and psychiatric nurses. Results showed significant improvements in global functioning in both the app and control groups, suggesting that rehabilitative treatment contributed to overall progress. Suicide risk did not significantly change within groups, although improvements were seen in the full sample, likely due to clinical care rather than app use. Only the experimental group demonstrated increased psychological empowerment, indicating that the app may effectively enhance patient engagement and involvement in their own care.
