Based on the text provided, it is unclear what the Starstruck app does as the text appears to be a list of links to various sections of the Apple Store website.
The text mentions the app can be downloaded on iPhone, iPad, and iPod touch devices and that it allows users to message anyone, but there is no further information on its specific function or features.
It is possible that the app is a messaging platform, but additional research beyond the provided text would be necessary to confirm this. However, there appears to be no indication that the app is related to AI or machine learning.
As such, it would not be appropriate to catalogue this tool as an AI tool.
