I’d imagine it is just a matter of time before Nintendo sends Apple a C&D, before this gets taken down?
Edit: Welp, that didn’t take long. Hopefully anyone who cares got a copy on their phone and don’t change phones for the foreseeable future.
As long as it doesn’t include a bios file, and is completely free (including no in app purchases), I doubt it. Emulators like igba are all over the Google play store, Nintendo only shows its fangs when they try to make money or contain proprietary code.
And actually, looking at it

There are paid android emulators on google play, so if Nintendo hasn’t already taken them down, I can’t see them doing that here
An emulator, even a paid one, would be totally legal in the US as long as:
Number 1 is a non-issue for a GBA emulator. Number 2 is more tricky, but it's always possible to reverse engineer and reimplement the firmware. That's protected by the Compaq v. IBM case.
The recent drama with the Switch emulator is that they violated the second principle.
What proprietary code did they have?
Stupidly, the decryption key.
Which is probably not copyrightable. A key is just a number, and copyright only applies to creative works. In a court, Nintendo would have to argue that copyright does apply because the key was created via some artistic or creative process by a human. It likely is just the output of a random number generator. Also, we’ve already been through this when people figure out how to decrypt DVDs.
You’re forgetting about the DMCA.
It was not taken down because of Nintendo, xD, the emulator was a copy of GBA4iOS and did not mention that it is based on GBA4iOS.
That was Apple’s fear.
But this app has no ROMs and the search page only takes you to a public domain homebrew ROM page. You can add and run your own ROMs but they don’t even mention it for fear of crossing Apple or Nintendo.
