That's probably because AFAIK Apple doesn't allow process forking, making any Tor-based messenger almost impossible to run as Tor would have to run as part of the main thread.

It's because iOS needs push notifications to resume background apps, and there's no secure way to do the push notifications

but having the bluetooth part working on iOS should not be an issue right?

This is entirely false, Apple allows the use of threads in their applications.

Oh I found a better explanation

>iOS doesn’t allow apps to fork subprocesses. While on the desktop Tor is running as a separate process, on iOS Tor is hacked to run as a thread inside the app itself. Therefore, you can’t have a system-wide Tor process like desktop and Android. If Tor is running in one app, and you open a different one, it’s not automagically going to start using Tor.
