This study aims to assess whether the Duolingo application is effective in increasing students’ vocabulary in the English learning process. A pre-experimental study design using a quantitative method was used. 32 pupils from class VII-1 made up the sample, which was chosen by simple random sampling. Pre- and post-questionnaires were used to collect the data. The null hypothesis (HO) was rejected and the alternative hypothesis (HA) was accepted when the data analysis showed that students' vocabulary increased significantly when they used the Duolingo application, as evidenced by a t-test value smaller than P (0.000 < 0.05). Therefore, it was determined that the Duolingo program at SMP Negeri 10 Bantimurung's class VII-1 efficiently expands students' vocabulary during the English learning process.
