Free Ipad Games Download

This is extraordinary. Most of my communicants use Whatsapp. I haven't asked them if they use ipad, but I think some/lots of them use iphone. Does iphone support whatsapp? Certainly my android tablet has whatsapp. Being peremptorily told by apple forums to 'google whatsapp' diminishes my confidence in ios. This is the first ios device I've had. I'm getting the vibe that I'm too stupid to use ipad.
