Does the iPhone have a pedometer?

Excuse me, could you please clarify something for me? I'm curious about the iPhone's capabilities and I was wondering if it comes equipped with a pedometer. You know, a feature that tracks the number of steps you take throughout the day. I've heard some smartphones have this feature built-in, so I'm just wondering if the iPhone also has this handy tool. It would be really convenient for tracking my fitness goals and monitoring my daily activity levels. So, does the iPhone have a pedometer, or would I need to rely on a separate app or accessory for that purpose?
