<![CDATA[The advancement of mobile technology provides opportunities for digital transformation in small-scale property businesses, including boarding house (kost) management. This research focuses on developing a Mobile-Based Reminder Online Payment Application for Kost using the Mobile Application Development Life Cycle (MADLC) method. The application is designed to automate payment processes through a virtual account system and provide real-time reminder notifications for both tenants and owners.The development stages included requirement identification, system design using UML diagrams, database structuring with MySQL, and interface implementation. The testing process employed User Acceptance Testing (UAT) to validate system functionality and user satisfaction. The results show that users successfully received automatic payment notifications based on the configured due dates, and all online payment transactions were accurately recorded in the system database without errors. This study concludes that the MADLC approach effectively supports the structured development of mobile applications for digital payment and reminder management in boarding houses. The UAT results confirm that the application meets user expectations in terms of functionality, ease of use, and transaction accuracy.]]>
