I switched from WhatsApp to Riot, connecting to the public matrix.org server, and it's working well for me. The app is pretty nice. It looks like any other modern chat app. The end-to-end encryption had some issues earlier (last year?), losing my encryption keys and making all messages in the conversation unreadable, but it seems to be working well in the latest version. It still warns you that encryption is experimental when you enable it, though.
