How do I get a free step counter?

Hey there, I'm curious about how I can get a free step counter. I've heard they're great for tracking my daily fitness goals, but I'm not sure where to start. Are there any apps or websites that offer them for free? I'd love to hear about any options you might have in mind. Ideally, I'm looking for something that's user-friendly, accurate, and doesn't require any additional hardware. Do you have any recommendations? Thanks in advance for your help!
