Facetime app?

My niece is growing up so fast, on the other side of the country, and I'm not getting to interact with her as much as I would like. Can one recommend me a reputable site to download a Facetime app that will run on a Windows PC, with no input from any Apple devices (which I don't have)? I found a site, ( https:\/\/facetimeforwindowspc.org\/facetime-for-pc\ ) but I'm not sure I trust it. (Tried Skype, but apparently that's too outdated for my brother to handle.)
