What factors can affect heart rate measurement results?

Improper wear can interfere with accurate heart rate signal detection. For example, gaps between the sensor and your skin—caused by a loose fit—can let in ambient light, while arm movement or slight shifts of the ring on your finger may also disrupt readings. Additionally, wearing the ring too tightly, raising your arm, or clenching your fist can restrict blood flow, which may similarly impact heart rate accuracy.

For the most reliable measurement, rest your arm flat on a surface, keep it relaxed and still, and ensure the ring sits snugly against the fleshy underside (pad) of your finger.

Note: Even with proper fit, individual physiological differences—such as skin tone, hair, tattoos, or scars—can sometimes influence heart rate signal quality.
