NOÉ by YON-E Mobile App Design

YON-E is an innovative health-tech brand focused on data-driven wellness experiences. NOÉ by YON-E is its premium mobile application, built to help health-conscious users track complex biometric data and get precision insights for their cycle and fertility journey.

Paired with the NOÉ Device, the app translates sophisticated scientific biomarkers like body temperature and pH levels into clear, actionable daily health insights.

Our goal was to design a seamless, tech-forward mobile app experience that sets a new standard in mobile health.

The digital health market is growing fast, but few solutions combine advanced biomarker tracking with a truly premium user experience.

The challenge was twofold. First, we needed intuitive data visualization for complex physiological metrics that wouldn't overwhelm the user. Second, we had to create a sophisticated, high-end visual language that balances technological authority with empathetic care.

We followed a four-stage design process. In Discover, we ran research, competitor analysis and built the information architecture. In Define, we created structural wireframes to map out screens, prioritize content and ensure a clear user flow.

In Develop, we collected moodboards and explored three visual directions: dark tech precision, warm glassmorphism and a bio-futuristic violet aesthetic with a glowing orb visualizer. Evaluated on brand fit, data clarity and user connection, the third concept was selected for an ultra-premium HealthTech feel. Finally, in Deliver, we built the UI kit, a clickable prototype and animations.

A step-by-step onboarding flow builds privacy trust with clear encryption messaging, captures essential cycle data and helps users pair the NOÉ Device in a few gentle steps, with clear progress tracking throughout.

The home screen delivers real-time body metrics such as pH and temperature, tracks the current cycle phase and gives quick access to insights, analytics, cycle history and emotional support resources.

An interactive calendar, daily phase tracking and symptom logging for mood, sleep and activity sit alongside in-depth educational content, helping users understand how their body changes in each phase and how to support themselves.

A quick check-in flow uses interactive sliders and generative visuals so users can log sleep, stress and emotional state in just a few taps, while capturing the metrics that matter.
