Not officially. It's closed source, for now, though I plan on opening it up in the future. If you'd like to try it out before promoting it, there is a [third-party hosting the .apk](https://apkcombo.com/gpt4btc-chatgpt3-5-client/org.bitanon.chatgpt3/); however, I can't vouch for the safety of the third party host.

If you prefer, you can also link to the app's official website: https://chatgpt3-android.app/

Is there an APK link for those of us who prefer not to accept Google T&Cs?

Also, is it closed source? Couldn't find the repo.
