can I have simplex both on my laptop and my android phone
synchronized?

    ninos As far as I know, that's not really supported on SimpleX. There is a "use from desktop" option, but I've never tried it.

    If you have more questions about SimpleX, they have an active users group that's listed in their directory where there are many people who are happy to answer questions about SimpleX. Someone may be able to answer your questions here, but the SimpleX users group will have more people who can answer your questions with more up to date information.

    Instructions on how to use the directory are here: https://simplex.chat/docs/directory.html and the group is called "SimpleX users group".
