First impression: I created an account on desktop and on mobile. I used the same display name and password in both cases. I got two different addresses. Good.

I don't see any means to copy an identity across the boundary (e.g. with Telegram, I can participate in the same conversation as the same identity from multiple devices).

Which means one of two things happens:

1. Users are encouraged to use on dedicated device for all private communications.

2. If users want multi-device, they have to leak facts about their setup (one public key per device) to the people they're talking to.

(This isn't a criticism; I'm just observing the user experience.)
