Their “how it works” blog article is worth a read - they’re using a blackbox reverse engineering of the protocol (called PyPush) and re-implementing it natively in an android app, so there are no man-in-the-middle servers. It's pretty bonkers given how difficult Apple's spec-less tech can be to work with.

SnazzyLabs speculates it won't be shut down because of how it works, and that stopping this application would require a retooling of apple's entire authentication system both server-side and across all devices.

$2 a month subscription? They want people to pay for this? That’s gonna be a problem for Apple, this is going to get shut down by the end of the week.

This seemed exciting to me, so I just downloaded it. The only thing you can do when you open it is sign in with Google, which throws an error:null message. Oh well! Better luck next time.

great, now we need an open source implementation

I was interested in Beeper until I saw that it was run by the guy who ran Pebble.

Massive red flag for me. This'll be abandoned just like he did Pebble...

So, question of if they’re safe or not will come down to HOW they did the reverse engineering. If the same engineers that delved into the jailbroken iOS devices are the ones that wrote the code (which seems likely given the prototype came from a single person), they’re going to be in trouble. If they implemented a “clean room” reverse engineering though, then they’re likely safe from being sued over copyright violations. See Wiki

Am I the only one who can't get into this app right now? when I click the Continue with Google button I get a toast saying "google sign in error.null"

This is game changing.
