Calvin Santoso, our founder, conducted a study with the title “Evaluating Financial Literacy App Saku-in: TELOS-Based Assessment and Gamification Impact Study.” The study was aimed to evaluate the effectiveness of the Saku-in application in enhancing financial literacy among Indonesian students aged 6–15 years. The high feasibility of the application based on the TELOS Framework indicates that the Saku-in application is considered worthy of further development with an average TELOS score of 7.45. The integration of gamification elements (such as points and badge systems) was proven to significantly increase children’s engagement in learning to save money. Users of the gamified version visited the application an average of 11.31 times, far higher compared to the non-gamified version, which recorded only 5.71 visits during the 28-day trial period. In addition, usability testing showed a very high task success rate of 92.75%, indicating that the application was easy for children aged 6–15 years to understand, although it still requires dynamic content updates.
