Chromecast works with iPhone through the Google Home app, not through AirPlay

Chromecast does not connect directly to your iPhone the way AirPlay does. Instead, you use the Google Home app to set up your Chromecast device and then cast content from apps that support Google Cast. Your iPhone and Chromecast must be on the same Wi-Fi network. Once they are, you can send video, music, photos, and screen content from your phone to your TV through the Chromecast.

The process is straightforward: read the Google Home app, connect your Chromecast to power and Wi-Fi, add it to the app, and then use the cast button in compatible apps to send content to your TV. This guide walks you through each step.

Key Takeaways

  • read the Google Home app on your iPhone from the App Store before you set up Chromecast.
  • Your iPhone and Chromecast must connect to the same Wi-Fi network for casting to work.
  • After setup, you cast content by tapping the cast icon inside apps like YouTube, Netflix, Spotify, and Google Photos.
  • If casting fails, restart your Chromecast by unplugging it for 10 seconds, then plug it back in.

read and open the Google Home app

Open the App Store on your iPhone and search for "Google Home." Tap the app by Google LLC and select Get, then Install. You will need to authenticate with your Apple ID. Once installed, open the app and sign in with your Google account. If you do not have a Google account, create one at google.com.

The Google Home app is where you set up your Chromecast, manage your Wi-Fi network, and see which devices are connected. Keep this app on your home screen because you will return to it if casting stops working or if you need to adjust settings.

Set up your Chromecast device in the Google Home app

Plug your Chromecast into an HDMI port on your TV and into a power outlet. Wait 30 seconds for it to boot. On your iPhone, open the Google Home app. Tap the plus sign (+) in the top left corner and select "Set up device." Choose "Set up a new device" and follow the on-screen prompts. The app will ask you to select your home Wi-Fi network and enter the password.

During setup, the app will ask you to name your Chromecast (for example, "Living Room TV") and assign it to a room in your home. These names help you identify which device you are casting to if you have more than one Chromecast. Once setup is complete, your Chromecast will appear in the Google Home app as a connected device.

Confirm your iPhone and Chromecast are on the same Wi-Fi network

Casting only works when your iPhone and Chromecast connect to the same Wi-Fi network. On your iPhone, go to Settings, tap Wi-Fi, and note which network you are connected to. In the Google Home app, tap your profile icon in the top right, select "Home settings," and check which Wi-Fi network your Chromecast is using. They must match.

If they do not match, open the Google Home app, tap your Chromecast device, tap the settings icon (gear), and select "Wi-Fi." Follow the prompts to connect your Chromecast to the correct network. This is the most common reason casting fails.

Cast content from apps on your iPhone

Open any app that supports Google Cast—YouTube, Netflix, Spotify, Google Photos, Chrome, and many others. Look for the cast icon, which looks like a rectangle with a Wi-Fi symbol in the corner. Tap it and select your Chromecast device from the list. The content will begin playing on your TV within a few seconds.

While content is casting, your iPhone acts as a remote. You can pause, play, skip, and adjust volume from your phone. The cast icon will turn blue or white to show that casting is active. To stop casting, tap the cast icon again and select "Stop casting."

Cast your iPhone screen to your TV

You can send your entire iPhone screen to your Chromecast, not just content from individual apps. Open the Google Home app, tap your Chromecast device, and select "Cast my screen." Your iPhone screen will appear on your TV. This is useful for showing photos, browsing the web, or demonstrating something on your phone to others.

Screen casting uses more battery and Wi-Fi bandwidth than casting from an app, so it may be slower. To stop screen casting, tap the cast icon in the Google Home app and select "Stop casting." Your iPhone screen will no longer appear on the TV.

Troubleshoot when casting does not work

If the cast icon does not appear in an app, that app does not support Google Cast. Check the app's settings or help section to confirm it has casting built in. If the cast icon appears but your Chromecast does not show up in the list, restart both devices: unplug your Chromecast for 10 seconds and plug it back in, then close and reopen the Google Home app on your iPhone.

If casting starts but stops after a few seconds, your Wi-Fi signal may be weak. Move your Chromecast closer to your router or move your iPhone closer to the router. If your Chromecast is far from your router, consider using a Wi-Fi extender. Restart your router by unplugging it for 30 seconds if multiple devices are having trouble connecting.

Frequently Asked Questions

Can I use Chromecast with AirPlay on my iPhone?

No. Chromecast and AirPlay are separate systems. Chromecast uses the Google Home app and works through Wi-Fi. AirPlay is Apple's system and works with Apple TV. Your TV must have a Chromecast device plugged in to use Google Cast from your iPhone.

What if I do not have a Google account?

You need a Google account to set up Chromecast and use the Google Home app. Create one for free at google.com. You only need to set up the account once; after that, you can cast from your iPhone without signing in again.

Can I cast from multiple iPhones to the same Chromecast?

Yes. Multiple iPhones can cast to the same Chromecast as long as they are all on the same Wi-Fi network. Only one device can cast at a time, though. If two people try to cast simultaneously, the second cast will take over and stop the first one.

Does casting use a lot of data from my phone plan?

Casting uses Wi-Fi, not cellular data, so it does not count against your phone plan. Your iPhone and Chromecast communicate through your home Wi-Fi network. If you are casting outside your home, you would need to connect to that location's Wi-Fi.

Why does my Chromecast keep disconnecting from Wi-Fi?

Move your Chromecast closer to your router or remove obstacles between them. Chromecast has a shorter Wi-Fi range than most phones. If the problem continues, restart your router and your Chromecast. If you have a 5GHz Wi-Fi network, try connecting your Chromecast to the 2.4GHz band instead, as older Chromecast models work better on 2.4GHz.
