The Louva Ring 2 uses optical heart-rate sensing, SpO₂ photodiodes, and motion-tracking algorithms similar to those used across modern health wearables. Accuracy can vary based on fit, skin temperature, and movement, but the system is designed to provide stable, trend-based insights rather than clinical measurements. For the most meaningful results, focus on changes and patterns over time within the app, rather than comparing readings to other devices or medical tools.
