Moodbuddy is a mobile-based gamified wellness application designed to help young Indian professionals manage daily stress, anxiety, and emotional fatigue through engaging, non-clinical interactions. Aimed at users aged 20–35, the project addresses the hesitation around seeking mental health support due to stigma and lack of awareness. Moodbuddy encourages the formation of healthy emotional habits through mood tracking, guided journaling, mindfulness mini-games, and a gamified companion system where a digital “buddy” evolves with user engagement. The design followed a human-centered process, beginning with secondary research, user surveys, and interviews, leading to personas, journey maps, and core feature flows. The visual language combines minimal UI with vibrant illustrations inspired by approachable wellness apps to resonate with a millennial audience. The final outcome includes high-fidelity screens, a cohesive design system, gamification assets, and culturally contextual features that make self-care intuitive, rewarding, and emotionally engaging.
