No it's provided as part of the Android OS. Very simple and intuitive to use and has been for the past 10 years since I started using it. The only thing that was annoying initially was that you couldn't pass through the WiFi that your phone is connected to but I think that was corrected in later versions of Android. For a time I was using one of my older Pixel phones as a WiFi extender to improve signal in my home's basement. Worked like a charm. I'm honestly surprised this isn't available on iOS.
