Fit Link

Unlike most trackers that rely solely on accelerometers, the Fit Link uses a multi-sensor array to measure skin temperature, heat flux, and galvanic skin response. This allows it to calculate calorie burn and activity intensity with significantly higher precision than devices that only count steps.

The Fit Link is designed to be worn on the upper arm, which many users find less intrusive than a wristband during sleep or intense workouts. While it is lightweight, you will notice it initially, but the secure fit ensures it stays in place without slipping during movement.

Yes, the Fit Link ecosystem relies on a subscription service to process the complex biometric data collected by the sensors. This dashboard provides the deep-dive analytics and trend reporting that make the device's specific sensor technology useful.

The Fit Link is water-resistant, meaning it can handle sweat and light splashes, but it is not waterproof. You should remove it before swimming, showering, or submerging it in water to prevent damage to the sensors.

Because it tracks physiological data like skin temperature and perspiration rather than just movement, it is generally more accurate at capturing calorie burn for non-step activities like weightlifting or cycling. It is an excellent tool for those who need precise metabolic data rather than just a general activity estimate.
