Despite its simplicity of design, the device requires the right setup to unlock its full potential, from an accurate pedometer to smart smartphone notifications. Many users experience problems when they first connect — the bracelet doesn’t sync, doesn’t show data, or discharges quickly. In this article, we’ll break down the step-by-step setup from scratch, including hidden features that the manufacturer doesn’t advertise.
