Now in beta on Android & Desktop, coming soon to iOS:

Save custom nicknames & notes for anyone you’re chatting with on Signal, even if they aren’t in your phone’s contacts. Useful for adding missing letters in a lazy friend’s profile name or a reminder about where you met.

@signalapp Will you be supporting WhatsApp this year. Would love to move those chats to your app.
@cabinet20 @signalapp Whatsapp has very privacy invasive requirements to connect to their servers. We don't want Meta's rules here in Signal network.
@jdoe @signalapp Fully understand. Sad that I can’t just use the Signal app, instead, as I can’t give up WhatsApp without giving up on talking to family or friends with Android phones.

FWIW, I'm happily using signal on an Android phone, linked to the app on my windows laptop, and communicating regularly with friends wholly w/in the Apple ecosystem.

The only challenge is convincing WhatsApp users to give up Meta; most of my friends were happy to do so.
