Where can I find my step counter?

Excuse me, could you please clarify where I might locate my step counter? I've been looking for it, but I can't seem to find it anywhere. Is it a separate app on my phone, or is it integrated into a fitness tracker I might have? Perhaps it's a feature on my smartwatch? I'm quite interested in monitoring my daily steps to stay active and healthy. Could you please point me in the right direction? Thank you in advance for your assistance.
