Context
Injoy supports people with bowel conditions (irritable bowel syndrome, Crohn’s disease, etc.) in tracking and improving their digestive health.
The service rests on three pillars:
- Test kits — to analyse patients’ gut flora.
- The Beacon — a sensor placed in the toilet to measure time spent.
- The app — which centralises data, lets users log symptoms and meals, and delivers personalised recommendations.
When I joined, Injoy was still shaping its design practice. I took on significant responsibility and worked directly with Hsingii, the lead designer.
Research and problem framing
A major project I led was the full redesign of nutrition tracking. This feature was critical because patient recommendations relied heavily on the food data collected.
Through in-depth user research, I identified several major friction points in the existing experience:
- Long, complex flow — users struggled to log meals every day.
- Low engagement — difficulty tracking meals regularly hurt recommendation quality.
- Inefficient search UX — adding several foods required reopening search multiple times.
To structure my approach, I defined user stories that helped prioritise work against user needs.
Ideation and exploration
Before moving into detailed design, I ran several ideation steps to refine the solution:
These steps built a solid foundation before high-fidelity design.
Solution
After analysing pain points, I proposed improvements validated with my manager and the lead designer, then shipped incrementally in development sprints.
Calendar view and streaks
Added a weekly view so users can easily see which days they logged meals.
Introduced a streak system to encourage more consistent tracking.
Simplified search and multi-select
Replaced the old search with a bottom sheet, avoiding navigation to another screen.
Added multi-select so users can pick several foods in one interaction, greatly reducing time to log a meal.
Nutritional context
Integrated informative bottom sheets explaining key concepts such as portion sizes and nutritional balance.
Favourite foods
Added favourites for quick logging of frequently eaten foods with preset quantities.
Project outcomes
This project was a rewarding experience that let me combine design and product strategy. Redesigning Injoy's nutrition tracking led to a more engaging, intuitive experience aligned with research findings.
This redesign enabled us to
- Reduce the time needed to log a meal.
- Improve understanding of nutritional data.
- Increase consistency of food tracking, strengthening the quality of medical recommendations.
Working on this project, I learned to balance user experience, technical constraints, and engagement while collaborating effectively with stakeholders. It was a major step in my growth as a product designer.
