The Use of Android Apps to Promote Healthy Lifestyle

Abstract

The rapid evolution of mobile technologies offers new and low-cost opportunities to improve including in public health, particularly food literacy for students, that remains challenging in many schools today. Limited information displayed at the food labels often causes health problems that can impact both short and long term. Therefore, this study aims to propose mobile application called NutriBuddy, that works based on Android which is designed to allow students to retrieve nutrition information through barcode scan including protein, sugar, salt, and saturated fat content, for each of food products. This study followed a systematic structure that includes analysis, literature review, system design, development, and testing. From the test result it’s confirmed that accurate barcode decoding, reliable database retrieval, and history data persistence are successfully performed, while usability feedback indicated that the application is intuitive, engaging, and useful as an educational nutrition aid. Thus, with this NutriBuddy application, hope it can serve as a digital tool that can be used by students to enhance their awareness and support healthier food choices.
