iPhone Casting Works Through Apps, Not Built-In Casting

Your iPhone does not have a native Chromecast button the way Android phones do. Instead, you cast from individual apps that have Chromecast built in. YouTube, Netflix, Spotify, Google Photos, and dozens of others let you send video or audio to a Chromecast from within the app itself. The cast button appears inside the app you are using, not in your phone's settings.

This means you cannot cast your entire iPhone screen to a Chromecast the way you can with AirPlay and an Apple TV. You can only cast content from apps that support Chromecast. If an app does not have a cast button, that app cannot send to Chromecast.

Your iPhone and Chromecast must be on the same Wi-Fi network for casting to work. If you are on a guest network or a different band of your home Wi-Fi, the cast button will not find your device.

Key Takeaways

  • Casting from iPhone happens inside individual apps like YouTube or Netflix, not from a system-wide menu.
  • Your iPhone and Chromecast must be connected to the same Wi-Fi network before you can cast.
  • The cast button usually appears as a rectangle with curved lines in the corner of the app's playback screen.
  • Not all apps support Chromecast; check the app's menu or help section to confirm it has casting built in.

Finding and Tapping the Cast Button

Open the app with the content you want to cast — YouTube, Netflix, Spotify, or another app that supports Chromecast. Start playing the video or audio. Look for a cast icon, which typically looks like a rectangle with curved lines coming from the bottom left corner. This icon is usually in the top right corner of the playback screen, sometimes next to volume or settings controls.

Tap the cast icon. A list of available Chromecast devices on your network will appear. If you do not see your Chromecast listed, check that both your iPhone and the Chromecast are on the same Wi-Fi network. Restart the app if the list does not populate after a few seconds.

Select your Chromecast device from the list. The app will connect and begin streaming to your TV. The cast icon will change appearance — usually turning blue or showing a filled-in version — to indicate an active connection.

Troubleshooting When the Cast Button Does Not Appear

If you do not see a cast button in an app, that app may not support Chromecast on iPhone. Check the app's settings or help menu to confirm. Some apps only support casting on Android. Others require a paid subscription before casting is available.

If the cast button is there but your Chromecast does not appear in the device list, verify both devices are on the same Wi-Fi network. Open your iPhone's Wi-Fi settings and confirm the network name. Check your Chromecast's setup by looking at the TV screen — it should show the network it is connected to. If they do not match, reconnect one of them to the correct network.

Restart your Chromecast by unplugging it for 10 seconds, then plugging it back in. This often resolves connection issues. If the problem persists, restart your iPhone and the app as well.

Controlling Playback After Casting

Once casting begins, your iPhone becomes a remote control. You can pause, play, skip forward or backward, and adjust volume from your phone. The app's playback controls remain on your iPhone screen. Your phone does not need to stay unlocked — you can lock it and use other apps while content plays on your TV.

To stop casting, tap the cast icon again and select "Stop Casting" or "Disconnect." The content will stop playing on your TV and return to your iPhone if you want to continue watching there.

Apps That Support Chromecast on iPhone

Major streaming services with Chromecast support include YouTube, YouTube TV, Netflix, Disney+, Hulu, HBO Max, Peacock, and Paramount+. Music apps include Spotify, YouTube Music, and Google Play Music. Google Photos, Google Drive, and other Google services also support casting.

The list changes as developers add or remove features. If you are unsure whether an app supports Chromecast, open it and look for the cast icon during playback. You can also search the app's help documentation or check the app's settings menu for a "Cast" or "Chromecast" option.

Casting Audio Only to Chromecast Audio or Smart Speakers

If you have a Chromecast Audio device or a Google Home speaker, you can cast music and podcasts from compatible apps. The process is the same: open the app, tap the cast icon, and select your audio device. Your iPhone screen can lock while audio plays.

Chromecast Audio devices are no longer sold by Google, but many people still own them. They work the same way as video Chromecast devices — they appear in the cast menu and receive audio from your iPhone's apps.

Frequently Asked Questions

Can I cast my entire iPhone screen to Chromecast?

No. Chromecast on iPhone only works with apps that have built-in casting support. You cannot mirror your whole screen the way you can with AirPlay to an Apple TV. If an app does not have a cast button, you cannot cast from it.

Do I need to be on the same Wi-Fi network?

Yes. Your iPhone and Chromecast must be connected to the same Wi-Fi network. If your phone is on a guest network or a different band, the cast button will not find your device. Check your Wi-Fi settings to confirm you are on the same network.

Can I use my iPhone for something else while casting?

Yes. Once casting starts, your iPhone acts as a remote. You can lock the screen, switch apps, or put the phone down. Content will continue playing on your TV. The app you are casting from stays connected in the background.

Why does the cast button not show up in my app?

The app may not support Chromecast, or you may need a paid subscription to unlock casting. Some apps only support casting on Android. Check the app's settings or help section to confirm Chromecast is available. If it is, make sure your iPhone and Chromecast are on the same Wi-Fi network.

What if my Chromecast does not appear in the device list?

Restart your Chromecast by unplugging it for 10 seconds. Check that both your iPhone and Chromecast are on the same Wi-Fi network. If the problem continues, restart your iPhone and the app. You can also restart your Wi-Fi router by unplugging it for 30 seconds.
