健身追踪器为何在达成每日步数目标时震动提醒

Fitness trackers count steps using built-in accelerometers that detect body movement patterns all day long.
Once your preset step goal is reached, the device sends a gentle vibration through your wrist.
This haptic feedback works even if your phone is in another room or on silent mode.
You can choose different vibration patterns for goals like active minutes or heart rate zones.
Some models add a soft LED flash alongside the buzz to help people with hearing differences notice it.
The vibration timing avoids interrupting meetings or classes by pausing during detected quiet hours.
Parents often set family challenges where kids feel proud when their tracker buzzes together.
It’s designed to motivate without pressure — no sound or screen pop-up unless you choose one.
Battery life stays strong because vibrations use far less power than constant screen lighting.
