Floodlight Cam

I am considering purchasing my first Ring product, a floodlight Cam. I do not have Amazon Echo, I am using Google Home. I have an android phone, apple IPAD and Windows 10 desktop. 1) f I purchase a Ring floodlight Cam, will it work with my devices ? 2) What functionality wll I lose without echo ? I don't want to have to purchase echo. 3) Do I need a subsription ? Will it work without a subscription .Thanks !
