Our team of three worked on improving the user engagement of a fitness mobile application under the supervision of the CEO. Based on our team's market research, I demonstrated a prototype for the new feature by creating and refining over 15 mock-up drafts forecasting the project's dedication to formulating a practical functionality and effective user flow for the new application features.

Collaborated with the CEO to understand the user needs and interests

3. Decide
-
Chose the most optimal intervention aligning with the company's business goals while prioritizing the user-centric design.
-
Categorized ideas based on urgency and importance to prioritize retrospectively

Compared between 2 features and identified the benefits for both users and service provider's side

Shifting from low-fidelity to interactive high-fidelity prototyping on Figma
-
Aligned with the brand image of soft and calming color tones while keeping the convenient functionalities and buttons for older people

5. Testing

Selected a diverse group of users that represented the target audience and observed their interaction with the prototyping of beta version
