Enhanced Sports App Development for Large-Scale Fitness Challenges

The client faces difficulties in scaling their existing sports application to handle a surge of up to one million new user accounts during major fitness challenges, ensuring system stability, fair activity tracking, and user engagement. Additionally, the current system requires enhancements to support competition management, social interaction features, and accurate activity data validation while maintaining optimal performance under high load conditions.

A mid-sized health and fitness technology company seeking to expand its mobile app offerings to support large-scale fitness initiatives and community engagement.

• Prepare the application infrastructure to reliably support up to 6,900 requests per second, including peak loads associated with large user influxes.
• Enable the system to handle the registration and onboarding of approximately 1 million new users seamlessly.
• Implement advanced caching, indexing, and database optimization techniques to reduce response times and improve data processing efficiency.
• Expand challenge management features to include inter-company competitions and community leaderboards.
• Integrate social features such as activity sharing, 'likes', and mutual monitoring to boost user engagement and motivation.
• Develop mechanisms to verify activity data authenticity from external sources and disqualify manual data entries for fair play.

• User registration system capable of managing up to 1 million new accounts during peak periods.
• Daily activity tracking with a calendar interface that highlights completed engagement (e.g., 30-minute exercise sessions).
• Challenge management module supporting individual, corporate, and inter-company competitions with flexible rules.
• Community and social features enabling users to connect, view peer achievements, and interact via 'likes' and comments.
• Leaderboards displaying performance metrics and challenge standings.
• Automatic detection and disqualification of manually entered activity data to prevent cheating, integrating with external health data APIs such as Google Fit and Apple Health.
• Backend system optimized for high request volume, including cache layers, query optimization, and database denormalization.

• Health data platforms such as Google Fit and Apple Health for activity metrics
• External challenge and competition organizers' APIs for challenge data synchronization
• Payment processing systems (e.g., Stripe, Apple Pay) if required for purchases within the app
• Notification services such as SendGrid for user communication

• System scalability to handle up to 6,900 requests per second during peak loads
• Support for up to 1 million new user registrations during event periods
• High system availability with minimal downtime
• Fast response times with optimized database and cache layers
• Robust data validation mechanisms for activity data integrity
• Secure data handling and user privacy compliance

The project aims to enable the client to support large-scale fitness challenges without system failures, significantly increasing user engagement by expected doubling of active users during events, and improving fair play and user trust through robust data validation mechanisms. Modernization and scalability of the app will enhance brand reputation and open opportunities for future large-scale health initiatives.
