UK Sports Technology Mobile Platform for Shooting Sports

About the client

A UK-based sports technology company focused on outdoor recreation, building an MVP mobile platform for real-time shooting sports performance tracking and community-driven engagement.

The Story

The client identified a lack of digital tools to measure, analyze, and enhance shooting sports. Their goal was to create a mobile-first platform that could automatically detect gunshots, synchronize performance data across multiple participants, and operate reliably in rural, low-connectivity environments. FiftyFive Technologies was engaged as the engineering partner, providing a dedicated cross-functional team to design, develop, and deliver the MVP from architecture to deployment.

Challenges

• > Acoustic source separation to distinguish local gunshots from background noise and other shooters.

• > Real-time multi-user state synchronization with intermittent and low-latency network conditions.

• > Continuous audio and sensor processing on mobile devices with minimal battery drain.

• > Offline-first operation to ensure zero data loss during connectivity drops.

• > Normalizing audio and sensor data across varied iOS and Android hardware.

The Solution

• > Engineered a hybrid Shot Registration Engine using TensorFlow Lite acoustic AI with accelerometer-based recoil validation.

• > Developed a React Native mobile app with custom native modules for low-level audio capture and sensor fusion.

• > Implemented Redux Toolkit with SQLite for offline-first state management and background sync.

• > Built Node.js backend with Express.js API and Socket.IO for real-time room-based synchronization.

• > Deployed BullMQ with Redis for asynchronous job queues handling notifications, emails, and data processing.

• > Structured PostgreSQL schema for relational integrity and AWS S3 pipeline for future ML retraining.

• > Integrated Firebase Cloud Messaging and APNs for reliable push notifications to active and offline users.

The Outcome

The MVP achieved >95% shot detection accuracy with <0.5% false positives, sub-200ms synchronization latency, and zero data loss under offline conditions. Optimized background processing ensured <5% additional battery drain per active hour. Beyond technical performance, the client gained a production-ready foundation for scaling, faster market entry, and strong user adoption potential. This engagement demonstrates FiftyFive Technologies’ expertise in delivering AI-powered, real-time mobile platforms—capabilities we extend to businesses across sports tech, healthcare, finance, and beyond.
