Mobile App UI/UX Design Healthcare App Onboarding Redesign

Phase is a hormonal cycle & nutrition tracker app that helps women sync their health and nutrition with their cycle. These onboarding screens are designed to immediately build trust and motivation by showing the app’s scientific foundation 🔬 and encouraging users to reflect on their progress 📊.

Most period tracking apps feel generic 😕, lack credibility, and fail to connect cycle tracking with real, actionable wellness insights.

To create onboarding that is both trustworthy and inspiring:

✨ Minimal, clean layouts keep focus on the core message 🎨 Soft pastel illustrations humanize the science 📱 Clear, empathetic copy builds immediate connection 💜 A modern, approachable tone reduces friction and increases trust
