Project Description
Project Description
Spiraw is a connected photobioreactor created by Food 4 Future, a Tunisian startup pioneering sustainable food innovation. The device allows individuals to grow fresh spirulina at home in a clean, controlled, and eco-friendly way. As a UX/UI Designer, I was responsible for designing the mobile app and the machine’s onboard interface, ensuring both products delivered a seamless and trustworthy user experience. My mission was to transform a complex biotechnological process into an accessible, intuitive journey for everyday users.

Goal
Goal
Grow fresh spirulina at home instead of paying for expensive ready-made supplements.
Easily set up and connect her Spiraw machine without technical knowledge.
Monitor growth and harvesting through a simple, reassuring app.
Integrate spirulina into her lifestyle with recipes, tips, and community support.
Frustrations
Ready-made spirulina products are costly and often processed.
Feels overwhelmed by scientific terms and unclear instructions.
Previous health apps felt cluttered and confusing.
Worries about wasting time or money if the machine seems unreliable.
Frustrations
Anxiety and stress about leaving her pet with strangers.
Difficulty finding someone reliable and affordable.
Fear that something bad could happen while she’s away.
Limited budget for traditional pet care services.
[Process]
01.
User Research
The project began with research and benchmarking of global IoT products and health apps. Interviews and analysis revealed the need for simple onboarding, real-time monitoring, and clear guidance, since spirulina cultivation is a technical process for most users.
02.
Define & Ideate
I created user flows for novice and advanced users—from account setup and QR-based machine linking to daily monitoring and harvesting—clarifying pain points and guiding a seamless, reassuring app experience.
03.
Design Solution
I designed a unified system for app and machine, with reusable components, clear feedback flows, and scalable guidelines, ensuring consistency and feasibility through close developer collaboration.
04.
Test & Iterate
I built interactive prototypes and tested them with users, then simplified language, visuals, and navigation to make the experience more intuitive and trustworthy.
