UX/UI Designer - Mobile App Redesign (iOS & Android)

Our fitness tracking app has 85,000 MAU and 2.3 star app store rating due to poor UX. We need a senior UX/UI designer to audit the current flows, conduct 8 user interviews (we provide participants), redesign the onboarding, workout tracking, and progress visualization screens, and deliver production-ready Figma files with a complete design system. Designer must have shipped native mobile apps before and understand iOS Human Interface guidelines and Material Design 3. Share your Figma community profile or case studies with your proposal.
