My family and I currently use Whatsapp to chat. We have group chats in there and it doesn't matter whether you have an iPhone or an Android phone, the app works and is easy to use.
I'm looking for an alternative. I want something I can self host, has encryption built in, and that has apps available for iOS and Android that are polished and similar to Whatsapp so that the family will actually take the leap and transition without too much pain or fuss.
Any suggestions?
