Building information architecture organized the logic and gave a framework for the information I wanted to include—reducing redundant repetition in later stages. I placed Home, Exercise, and Message in a sticky bottom menu because they are the most important features and should stay visible across screens. Profile stays in the top-right corner for less frequent tasks and clear separation.

I used a rose pink hue as the primary color to create a calming visual experience, helping users distance themselves from the stress of scoliosis. Gradient accent colors highlight important information and titles.

I conducted a usability test with three designer friends on the first version of the design. They surfaced issues with navigation and clarity; I incorporated their feedback into the second version.

Launch screens collect minimally four questions—name, age, curvature degree, and brace type. To reduce churn, it is crucial to foster positive emotion and motivation. An intuitive, simple home eases cognitive load when users are already managing brace wear: clear wear-time progress, incentives to complete required hours, and motivation to start today's exercise.

I used conversational UX to encourage continuity. Placing the exercise schedule on the home page hooks engagement beyond monitoring data alone. Rehab exercises are vital yet often missing in related apps; orthopedists highlighted their role in preventing muscle weakening and relapse—so the exercise section delivers personalized recommendations and motivational prompts.

Orthopedists have limited availability, which delays addressing brace compliance until appointments months later—often too late. Inspired by apps like Lemonade, I explored an AI assistant to resolve outsourceable compliance issues such as discomfort that may require brace modifications.

I tested the high-fidelity prototype in maze.co with eight users. Key findings: (1) users missed “notification” when it lived under an unrelated script like privacy settings; (2) onboarding pages were essential—without them, almost no one could infer the app's purpose at first glance.
