This research focuses on the development and feasibility analysis of GramApp as a tool for English language learning, particularly in grammar. The study employs the Research & Development (R&D) ADDIE model based on the Dick & Carey framework. Data collection involves observation, questionnaires with validity and suitability tests, and documentation. Validation of the learning media is conducted by experts in media and materials, as well as English teachers. The media was trialed with twenty-eight students from the X-2 class at Hasyim Asy’ari 1 High School. A mixed-methods approach is used for data analysis, utilizing percentages. Findings indicate that the media is deemed suitable for use, having received endorsements from experts with media and material scores of 94% and 92%, respectively, and from teachers with scores of 94% and 90%. Student feedback showed an 88% approval rate. Additionally, the media is engaging and enjoyable, making grammar learning easier for students.
