This study aimed to investigate the effectiveness of Let's Read application in enhancing tenth-grade students' reading skills at SMKN 2 Tarakan. It employed a pre-experimental design with a one-group pretest-posttest model, involving 24 students selected through non-probability sampling. Data were gathered using reading comprehension tests administered before and after the intervention using the Let's Read application. During the treatment period, students interacted with narrative texts through the application, accompanied by structured assignment activities. The data were then analyzed using SPSS 26 software, including descriptive statistics, normality and homogeneity tests, and paired sample t-tests. The results revealed a significant improvement in students' reading comprehension, with a p-value of 0.045, confirming the effectiveness of the application. These findings support the integration of digital tools such as Let's Read in English language teaching to increase student engagement and improve learning outcomes.
