Verizon uses web based controls for their Windows and Apple desktop/laptop customers. They at one time had a piece of software you downloaded, but they retired it, as it didn't work well, and it wasn't as cross compatible as doing it via their website.
You can see the offerings at www.verizon.com/fiostvonline

There is no current FiOS Mobile app for Windows or Mac. They only exist for Android and iPad.
