As of my last knowledge update in October 2023, specific skins in Fortnite, including exclusive ones like the ANDROMEDA skin, could vary based on events, seasons, or platform-specific promotions. Typically, most Fortnite skins can be acquired across all platforms, including iPads, through in-game purchases or challenges.
However, limited-time skins are sometimes exclusive to certain promotions or events. If ANDROMEDA is one of those limited-time or exclusive skins, the best way to confirm availability would be to check Fortnite's official announcements, the in-game store, or community sources like Fortnite-related social media or forums.
To increase your chances of obtaining specific skins, make sure to keep an eye on Fortnite's seasonal updates and events that may offer exclusive rewards.
