ANALISIS PENGALAMAN PENGGUNA PADA APLIKASI NGAJI.AI DENGAN MENGGUNAKAN METODE HEART METRICS DAN IMPORTANCE PERFORMANCE ANALYSIS (IPA)

Ngaji.AI is an AI-powered mobile application designed to facilitate
independent Qur-anic learning. Despite its potential, user reviews on the Play Store
highlight issues such as slow AI response, complex interface design, and limited
interactivity. Using the HEART Metrics method, which includes Happiness,
Engagement, Adoption, Retention, and Task Success, this study was conducted to
measure user experience —and Importance Performance Analysis (IPA) to identify
gaps between feature importance and performance. A questionnaire was
distributed to 100 users, revealing that although overall usability is rated very high
(85%), several core features fall into the improvement priority quadrant.
Furthermore, it is recommended to enhance such as; optimizing system
performance, simplifying the interface, and adding onboarding in gamification
elements to improve engagement. These findings offer insights for improving
Ngaji.AI and similar AI-based educational applications.
