Gain City is a gym training app I designed and prototyped in Figma to help users track their workouts, set personalized fitness goals, and stay motivated through progress insights and trainer support. I developed the brand identity and applied it across the mobile app, creating a cohesive visual system that extended through landing pages, feature screens, and interactive components. My design process included user research, wireframing, and high-fidelity prototyping to ensure a seamless, intuitive user experience.

I focused on designing clean, energetic interfaces that reflect the active and motivational spirit of the brand, using bold typography and dynamic color palettes to encourage consistency and engagement. This project deepened my understanding of end-to-end product design, from concept to prototype, and reinforced the importance of aligning user needs with strong visual storytelling.
