Hi @Dez Ladson
Welcome to the Community!
Unfortunately, it's not the same, when you click on Calendar within a board, it brings up a little calendar on the right hand side, where the menu was.
However, as @Antonio Panea has said, you can use the Chrome app on your iPad and then you'll be able to access everything that you can on a regular computer and the calendar will appear the same.
There are other things that are available using the Chrome app as well, such as all your PowerUps, card covers etc.
Hope that's helpful!
I had the same question. when I open trello on chrome and switch to calendar view on an ipad, it doesn't seem to allow me to drag a card from one day on the calendar to another. the trello help guide says that this is one of the things you can easily with the calendar power-up. (I'm expecting that by dragging a card to another day in the calendar view, trello will automatically update the due date to the new day.)
