A single app to chat on iMessage, WhatsApp, and 13 other chat networks. You can search, snooze, or archive messages. And with a unified inbox, you’ll never miss a message again.

It promises to be the one-in-all chatting app, based on matrix, providing compatibility to other apps (Telegram, Signal, WhatsApp etc.) through bridges.

So what do you think, from a privacy point of view and also user friendliness on the other hand?
