I might add that, given the intentions expressed below, in terms of doing this on a jailbroken iOS device via Cydia, the concerns raised in the Apple iOS SDK, that I referenced in the above linked post from 2010, essentially go away. 

They would still be germane, as may now be expressed in the current SDK, including the use of the new Swift language, if the OP's intent was to pursue this via official AppStore channels and am surprised that it was approved by Apple previously given the indicated content and functionality of the app.

The primary intention of jailbreaking an iOS device is, of course, to circumvent Apple's restrictions on the software that can be installed by using third party distribution channels and in the tools that can be used to develop apps.

That being said, the licensing issues, as Duncan raised in his reply, are still germane and permission from the R Foundation should be sought for any uses involving R Foundation copyrighted content. That would be relevant for both the iOS implementation and the Android implementation.

P.S. I echo's Duncan's comment, in that I am also a member of the R Foundation, but am not speaking here on it's behalf.
