Midnight Planets is available for iPad, iPhone and iPod Touch with iOS 6 and later, and for Mac with OS X 10.8 and later.
Sorry, no. iOS and Android (and Windows, etc.) are very different platforms and doing both well is not trivial. However, some of the website may be useful on those platforms, such as the Latest Images pages.
To focus on quality.
Also, iOS and Mac are not one platform; they are two related platforms with very different user interfaces. Supporting even just those two is not easy for a program this complicated.
