Gamified Fitness Challenge App

The Problem

Fitness apps fail at retention because working out alone is boring. Adding competition, stakes, and real rewards changes the behavior loop entirely.

What I Built

A gamified mobile fitness platform — users join exercise challenges, track completions, compete on leaderboards, and win cash prizes for top performance.

Technical Challenges

• Real-time leaderboard with fair ranking across challenge types
• Payment and prize distribution system with fraud prevention
• Challenge verification — ensuring reported exercise completions are legitimate
• Engagement loop design to drive daily active usage
