I'm not sure that they will. Granted, Android has a robust fraction of the market for phones - but Apple has the market practically cornered for apps. Their previous "Invisible Deck" app wasn't ported, as far as I know.
BTW: "Invisible Deck" is a good app, perfect for doing a card trick without the cards. "Premonition" is a variant of Invisible Deck, and a very powerful one - I saw the demo video for it and plan to get the app ASAP. I don't even know what it costs yet, and I'm still getting it regardless!
T11 has a "Rising Card" app for iPhone - it's yet another variant of Invisible Deck, but with a Rising Card effect as a bonus. I don't recall the name of David Blaine's iPhone app, but it's not as good - it has a success rate of maybe 50-70% in my experience. I can explain why, but I don't want to reveal the trick.
