Built in three months with a developer friend, Calori-Chan gamifies nutrition, hydration, and activity tracking. Using UX research and smart gamification strategies, we created a mobile experience that turns healthy habits into a fun and effortless part of your day.

Challenges

We had to build a level system to encourage daily use, while keeping tracking simple. The challenge was making meal and habit logging effortless, so progress felt rewarding without adding friction.

Achievements

• Designed a streamlined booking flow that reduced friction and increased student confidence in booking lessons online.

• Delivered a high-fidelity prototype and scalable design system, enabling the academy to expand its offerings digitally.

• Increased session duration by 20% with clear content strategy and tone.
