Fantastical for the iPad?

Hello all,
So, I've been using Fantastical for the iPhone for a few months now and love it. Its been getting me to use my calender more, which is a good thing. I have an iPad mini and I was thinking of getting Fantastical for the iPad for me, and to support the dev who's done such a great job with accessibility. Is there any big differences for the iPad app that I should know about? Is it any less accessible? Is it woth it for me to spend so much mony on the app?
Thanks in advance.
