Yes, it's a little complicated! Typically you use Whatsapp on your phone.
But for Macs and Windows machines, there's a Whatsapp desktop app that you can use .. in tandem with your phone ... to share your Whatsapp account. Basically you can use Whatsapp on your phone and tell it to share your chats/account with your computer. After that your computer just needs to have normal network access.
And ... the story with iPads gets a little more complicated. When you buy an iPad you can opt for one with cellular service. So Whatsapp "should" work. Except it doesn't because Whatsapp (now owned by Facebook) doesn't support it.
But on an iPad, you can use the iPad's web browser to go to whatsapp.com and share your Whatsapp account/chats that way. It's a little complicated. Instructions here .... https://www.thesun.co.uk/tech/11251625/how-to-get-whatsapp-on-ipad/
The browser approach doesn't work as well as a real app, but I guess it's better than nothing.
There are rumors of iPad support getting better, but they're just rumors for now.
Hope this helps
