I want to launch a loyalty gamification app that runs natively on both iOS and Android. The heart of the product is a simple but engaging reward loop designed to keep users coming back and talking about the brand. Core gameplay elements I need implemented are: • Points system users earn through specified actions • Achievements and collectible badges that unlock at set milestones • A real-time leaderboard that ranks participants and fuels friendly competition The UX should feel game-like yet intuitive for shoppers of all ages, with smooth onboarding and clear progress feedback. I will provide branding assets and the rules that govern how points are awarded; you handle everything from technical architecture to final store-ready builds. Send me a detailed project proposal outlining your recommended tech stack, milestone plan, estimated timeline, and any prior work that proves you can deliver a stable, engaging cross-platform experience. I will shortlist based on clarity of approach, creativity in keeping users motivated, and a realistic production schedule.
