UI/UX Design for Gamified Health App

I need a professional UI and UX design for a gamified health-tech app that helps users track their fitness progress while building healthy habits. The design should embody a minimalist and clean style, ensuring it is engaging, user-friendly, and reflective of the app's goal of making fitness tracking fun and intuitive.

Key features to highlight include:
- A fitness tracking dashboard
- Habit-building challenges
- A gamified rewards system

Additionally, please incorporate gamification elements such as:
- A leaderboard for progress comparison
- Achievement badges for milestones
- Daily streak tracking to encourage consistent use

This is an urgent project, so I’m looking for someone who can start immediately and deliver high-quality work promptly. Strong portfolios showcasing expertise in health-tech or gamified applications are a must.
