People's habits in using social media communication technology such as, WhatsApp, Instagram, Facebook, and others can be used as guidelines for designing online learning. One of the innovations in the learning system by utilizing technology communication that is Edunex. Edunex is a Learning Management System that developed by the Directorate of Education Development of ITB and can be accessed through the website www.edunex.itb.ac.id. However, according to Bernacki, accessibility on the website platform is lower than on the mobile platform. This causes the features provided by the Edunex are not accessed and used maximally. Therefore we need the Edunex mobile application to improve accessibility on Edunex. The Edunex mobile app is built with a native paradigm because paradigm native provides better user convenience compared to hybrids. Applications that are the result of research assignments is an iOS-based mobile application that is built using a framework SwiftUI and UIKit work. Students will be provided with features such as messages, exams, attendance, CRS, notifications, and viewing materials.Data displayed and processed on each feature of the Edunex mobile application will be the same as that on the site because it is integrated with the Edunex site server. After performing performance testing on the Edunex mobile application based on iOS by utilizing Sentry tools, the application is considered successful by achieving pretty good satisfaction. So that the application is considered capable of providing good user comfort by providing excellent performance satisfying. The performance tested on the application is the total crashes in the application, Apdex, failure percentage, and others.
