According to TiPb, it says that Lowtide runs the Apple TV interface as similar to how SpringBoard runs the iPhone, iPod touch, and iPad home screen system, and it looks like Apple designed the built-in iOS app with cross-device support considering developer Dunstin Howett got it up and running on an iPod touch 4.
Erica Sadun from TUAW explained is probably not something you’ll want to do yourself. Erica also added the reason as a pretty technical. Now extracting frameworks from the iPhone’s “dyld” cache system was not abundant to get the app to run (an approach which Erica initially tried). Instead, you need to use caches native to Apple TV, which is the approach Howett used. As reported by Erica.
