This system is baked into the Guardian's news app that millions of people have installed. Every regular user of the app generates cover traffic, and an attacker monitoring the network cannot distinguish someone using the secure messaging feature from a regular user.

I haven't read the white paper yet, but the Guardian app is full of trackers. Would this be a safer option than Signal?

I like the idea, I'm not sure of the implementation.

Here's the Exodus Report on their app

It's a dedicated feature for whistleblowing. If you have the contact details for a journalist in Signal already that works fine too.

Different threat models.

Do you know if there is there an android version of this? Their link points to the Apple store.
