Education plays a crucial role in optimally developing and directing students' potential. In the current educational context, learning outcomes are assessed based on students' abilities to solve problems, reason, communicate, and demonstrate knowledge and attitudes. However, preliminary studies at MAN 1 Banjarmasin revealed that only 62.85% of the XI Agama class students met the Minimum Completeness Criteria (KKM) of 75 in Fiqh subjects, while the rest failed. This study aimed to improve learning outcomes in the topic of Mawaris by using an Android-based learning media, the "Kalkulator Waris" application. This Classroom Action Research (CAR) was conducted through two cycles following the model proposed by Arikunto, comprising planning, action, observation, and reflection phases. In the first cycle, the average student score was 73.63 with a 62.85% success rate. After refining the learning process, the second cycle showed significant improvement: the average score rose to 88.17, and all students (100%) achieved mastery. The use of the "Kalkulator Waris" application facilitated students’ understanding of complex inheritance calculations, enhanced learning engagement, and fostered a more active, creative, and problem-solving learning environment. The findings suggest that appropriate use of Android-based educational applications can significantly enhance learning outcomes, particularly in complex subjects like Islamic inheritance law.
