Still not sure I have the best naming, so I asked ChatGPT. Think I'm sticking with the current naming.

I'm making an iOS app, where there's an option to either allow other apps such as Spotify to play in the background together with my app's sound, or my app's sound will be the only thing making sound.

what would be a good name for this option?

A good name for this option in your iOS app could be:

"Audio Mode"

Within this setting, you could provide two options:

1. "Mix with Other Apps" - This allows your app's sound to play together with other apps like Spotify.
2. "Solo Mode" - This makes your app's sound the only sound playing, pausing or stopping other audio sources.

This naming is clear and intuitive, helping users easily understand and select their preferred audio experience.

Give me some more ideas

Sure, here are some more ideas for naming this option in your iOS app:

1. "Sound Control"

   • Options: "Blend with Others" / "Exclusive Sound"

2. "Audio Preference"

   • Options: "Mixed Playback" / "Solo Playback"

3. "Playback Mode"

   • Options: "Combined Audio" / "Isolated Audio"

4. "Sound Settings"

   • Options: "Mix Audio" / "Single Audio"

5. "Audio Settings"

   • Options: "Allow Background Audio" / "Mute Background Audio"

6. "Sound Mode"

   • Options: "Shared Audio" / "Solo Audio"

7. "Audio Experience"

   • Options: "Multi-Source" / "Single Source"

8. "Listening Mode"

   • Options: "Overlay Audio" / "Primary Audio Only"

9. "Sound Options"

   • Options: "Allow Other Sounds" / "Only App Sound"

10. "Playback Preferences"

    • Options: "Concurrent Audio" / "Exclusive Playback"

These names are designed to be user-friendly and clearly convey the functionality of the audio settings in your app.
