Buying full version – Spaceflight Simulator Review

I love this game soo much. I have it on my iPad and iPhone and I want to get the full version. If I get it on my phone can I get it on my iPad for free(restore purchases) or do I need to pay for it again? It would help if I could get a answer but if not it’s still ok.
