Following the COVID-19 outbreak, teaching and learning have been forced to move fully to the Internet rather than the conventional offline medium. As a result, the use of M-learning has risen dramatically, which was neither expected or anticipated. The challenges and benefits of such widespread usage are beginning to emerge in front of us. Thus, in this paper, we systematically review the benefits and challenges of leveraging M-learning for Science and Technology courses during the COVID-19 pandemic by educators and learners. Related articles were obtained from various databases, namely, IEEE, ACM Digital Library, ScienceDirect, and Springer. In total, 4210 related articles were initially found. Upon executing careful selection criteria, 22 articles were selected for review. After that, the advantages and threats were identified and discussed. As per our findings, it was determined that M-learning has excellent potential to be an effective platform for education provided that the identified shortcomings are resolved. This review will be helpful for education stakeholders and institutions to gauge the impact of leveraging M-learning as the only means for education to proceed. Moreover, it reveals the strengths and shortcomings that would aid in adjusting the relevant policies administered by the institutions. Furthermore, application developers will be able to comprehend the expected features that should be included in novel M-learning platforms.

The aim of this study was to analyse the user-friendliness of the COVID-19 Response Mobile Application, namely PeduliLindungi. 107 respondents answered the questionnaire and concluded that the usability of the current version is 68%, which is categorised as ‘terrible' on the system usability scale, indicating that the main concern of users is the accessibility of the application. The main objective is to redesign the UI and UX of the PeduliLindungi mobile application to improve the usability and accessibility of the application. The quantitative method was used as a research tool to obtain the responses of PeduliLindungi users and measure the attributes of the application based on the ISO 9241-11 metrics: Efficiency, Effectiveness and Satisfaction. A revised version of the PeduliLindungi mobile application received a 70% usability rating and was rated "good" on the system usability scale. The study also identified specific usability characteristics from the ISO usability model widely used in usability engineering. A guide was created for developers to include UX considerations in the development of mobile applications
