MacBook pro

Welcome:

Bob’s answer is spot-on.

As you appear new to “Apple World” and are trying to learn ...

iOS is the operating system used on mobile devices (iPhones, iPads, etc.)

MacOS is the operating system for laptops and desktops.

There are a lot of “tie-ins” between the two systems, but they are entirely different and distinct computing environments.

You can not use iOS apps on your Mac. You can use apps made for MacOS.
