The app is a PsyOP by ICE to deport more Immigrants, and this whole stunt might as well be a part of it
The GrapheneOS team already did a great disection of this iOS only app and why it is not anonyme at all (+ that they are fucking lying about Aosp and encouraging People to buy a phone known for spying on them
Therefore, its extremely easy to guess that at some point the US is going to Apple HQ with a court order to disclose everyone who downloaded the app, since, once again, iOSs App store discloses such things to Apple.
