Why We Build This Way
Why Edge-First?
Moving computation to the edge isn't just about privacy — it's about creating a more reliable, responsive system. When your insights don't depend on connectivity, they're always available when you need them. This architecture also enables features that would be impractical with cloud-only processing.
Designed for Extensibility
The OneSync architecture is built to evolve. New sensor modalities, updated ML models, and enhanced features can be deployed via secure OTA updates. The system is designed to grow with advances in wearable computing while maintaining backward compatibility and data integrity.
