This study aims to analyze the impact of the EduLearn app-based, cross-disciplinary learning medium on elementary school students' Indonesian language literacy skills and their understanding of Pancasila values. This quantitative study employed a quasi-experimental design, specifically the Non-equivalent Control Group Design. The research subjects consisted of 28 students in the experimental group (using the EduLearn app) and 28 students in the control group (using conventional media). Data were collected through expert validation and pretest-posttest instruments. Validation results indicated that the EduLearn medium was highly suitable for use, with a validity score of 91.00%. An Independent Samples t-Test yielded a significance value of 0.000 (p < 0.05) for both dependent variables, a finding reinforced by the MANOVA test (F-calculated = 48.215; Sig. = 0.000). The experimental group's average posttest scores reached 86.79 for Indonesian language literacy (N-Gain = 0.69) and 87.86 for the understanding of Pancasila values (N-Gain = 0.71), significantly surpassing the control group. Effect size calculations (Cohen's d) of 2.32 and 2.37 confirmed the medium's effectiveness as falling within the "very high" category. In conclusion, the EduLearn app proved effective in simultaneously enhancing elementary school students' literacy skills and their understanding of Pancasila values
