Echobody — Tactical Fitness Game
A high-stakes competitive fitness platform transforming real-world runs into a territorial domination game.
About the company
Echobody is a high-stakes competitive fitness platform that transforms your physical runs into a territorial domination game.
Pilots capture physical grid sectors, neutralize enemy claims, and interact with a context-aware Voice & Text AI advisor while climbing the global leaderboard.
Projects tasks
To build a high-performance, geometry-intensive GPS game, we tackled the following core technical challenges:
Spatial Domination Engine
Engineered a complex spatial engine using Turf.dart to process real-time ray-casting, loop validation, and the 80% territory domination logic.
Zero-Dropout GPS Tracking
Built a custom Location Service utilizing Android Foreground Services to guarantee uninterrupted, high-precision GPS tracking during intense physical runs.
Generative AI Advisor
Integrated Google Generative AI (Gemini) with Text-to-Speech to create "Echo AI", a context-aware tactical advisor rendering real-time radar stats.
Results & Impact
100%
GPS Uptime in Sorties
<50ms
Geometry Calculation
5-Layer
Clean Architecture
The Challenge
Building a location-based game requires processing complex geometrical intersections in real-time on a mobile device, while simultaneously ensuring bulletproof GPS reliability and preventing battery drain during long physical runs.
Our Solution
We adopted a strict 5-Layer Clean Architecture in Flutter with Riverpod state management. The app leverages Mapbox for tactical rendering, Firebase for real-time global syncing, and highly optimized custom geometry algorithms to calculate territory captures instantly.
Successfully Delivered
Echobody turns physical activity into a strategic turf war. Users deploy "Echoes" (GPS sorties) to run closed loops, capturing physical grid sectors and neutralizing enemy claims using complex spatial geometry and the "80% Domination Rule".
