This study examines the practicality of Android-based learning media in improving students’ ability to use electrical measuring instruments in the Industrial Revolution 4.0 era. This study adopted a research and development (R&D) approach using the 4D model. The research process involved practical use tests conducted by lecturers and students using a questionnaire that evaluated convenience, time, and usability. The study’s results revealed that learning Android-based media for mobile learning showed a level of practicality that deserved a thumbs up. Aspects of convenience, time, and use all reach a good level of practicality, so they fall into the ‘practical’ category. Based on research findings, using Android-based learning media for mobile learning provides significant benefits to learning through easy access to learning materials, better interactive and practical visualization, efficiency of learning time, and self-evaluation. The benefits received can be added to understanding the use of electrical measuring instruments. However, the Android-based learning media currently being developed has not been integrated with artificial intelligence (AI), so there are still great opportunities for further research into its integration with education.
