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.
I’ve been using Beeper for almost two years now on desktop to view my iMessages, discord, and slack all in one app, and Apple hasn’t said or done shit about it yet
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.
I get why they want to charge money, that’s obvious. But they are charging money for another companies service - that’s not a good business plan. Especially when that other company is one of the largest in the world.
Although, what’s the worst that happens if Beeper dies in a couple months? Your bubbles turn green on iOS.
Media quality between platforms is finally getting addressed with Apple adopting RCS.
Only real gap is cross-messaging-platform end to end encryption, which is also on the roadmap for RCS. And if you’re really worried about security, handing over your iCloud credentials to a third party probably isn’t a great idea anyway.
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.
Okay, I went through the troubleshooting and got it working. It's pretty cool. I can edit, see iPhoners typing, reply directly to a text, add reactions to images, and edit a text. No fancy effects though, like the laser beams. I guess this is a pretty good solution until things become standardized. Thanks!
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
Edit: I just read the article you linked. Why do we need to sign in with Google at all? Granting an unknown publisher access to my Google account, which knows pretty much everything about me, including financial information, seems unwise.
