ChatGPT has an official app now. You can even talk to it.

This week, OpenAI released a new ChatGPT app meant for use on iPhones and iPads. It's free, syncs with your existing chat history and you can even talk to it -- sort of. While you can blurt out things for the app to transcribe and respond to, the experience is pretty basic; in other words, don't expect it to talk back at you like Siri or Alexa.
