This study aims to analyze the effect of using the Readable application on the reading comprehension ability of eleventh grade students at Nommensen Campus Private High School. This study used a quantitative approach with a quasi-experimental design involving 50 students, consisting of an experimental class and a control class. Data were collected through pre-tests and post-tests, then analyzed using an independent sample t-test. The results showed that the use of the Readable application had a significant effect on improving students' reading comprehension ability, with a significance value of 0.000 (less than 0.05). In addition, the experimental class showed a higher increase in learning outcomes than the control class. Thus, the Readable application can be used as an effective learning medium in improving students' reading comprehension ability.
