What app should I use for private chatting/pics/links with my partner? We both have iphones and like the native messaging app, but want a segregated app that can be locked so kids using our phones won't stumble upon a private message.
We'd like something full-featured (emojis, reaction buttons, tc.) but I don't want anything run by Facebook or any of its subsidiaries. Something that would be usable on other devices as well would be a plus (especially apple watch), but not as important.
