I personally love Threema [1], which is available for iOS, Android, Microsoft and Web. It uses a random ID to identify users, uses End-to-end encryption, you can make voice calls, send messages, audio messages, GIF’s etc.. Oh, and it has a dark theme! Please note that Threema is not open source. If you want that go for Signal instead. [1] - https://threema.ch/en https://threema.ch/en
