The iOS simulator is really just a tool for developers to develop apps with. You wouldn't be able to download H9 Control into it, connect to an H9 over Bluetooth, and start making in app purchases with it.
We are considering doing an Android version of the app in the future, but right now, we're concentrating on adding the store functionality to the MacOSX and Windows version of the app and adding support for the existing Factor stompboxes.
