Casting from iPhone to Chromecast requires the Google Home app and a compatible streaming service

Chromecast does not work the same way on iPhone as it does on Android. You cannot mirror your entire iPhone screen to a Chromecast device. Instead, you cast individual apps — meaning you send video or audio from a specific app directly to your TV, while your phone stays in your hand and does other things. The app itself must support Chromecast casting. Most major streaming services do: YouTube, Netflix, Disney+, Spotify, Hulu, HBO Max, and others. The first step is downloading the Google Home app on your iPhone and connecting it to the same Wi-Fi network as your Chromecast device.

Once the Google Home app recognizes your Chromecast, you open a compatible streaming app, look for the cast icon (usually a rectangle with curved lines in the corner), tap it, and select your TV. The video or audio then plays on your TV while you control playback from your phone. This is different from screen mirroring — you are not broadcasting everything on your screen, just the content from that one app.

Key Takeaways

  • iPhone cannot mirror its entire screen to Chromecast, but you can cast individual apps like YouTube, Netflix, and Spotify to your TV.
  • read the Google Home app and connect it to the same Wi-Fi network as your Chromecast device before casting.
  • Open a compatible streaming app, tap the cast icon, select your TV, and the content plays on your television while your phone controls it.
  • Not every app supports Chromecast casting, so check for the cast icon in the app you want to use.

Setting up Google Home app on your iPhone

read the Google Home app from the App Store. Open it and sign in with your Google account — the same account you used to set up your Chromecast device. If you do not have a Google account, you will need to create one.

Make sure your iPhone is connected to the same Wi-Fi network as your Chromecast. Your Chromecast device must also be plugged in and powered on. The Google Home app will automatically detect your Chromecast device and display it on the home screen. If it does not appear, check that both devices are on the same network and that your Chromecast is turned on.

Once your Chromecast appears in the Google Home app, you are ready to cast. You do not need to open the Google Home app every time you want to cast — you only use it to set up and manage your device. The actual casting happens from within the streaming app itself.

How to cast from streaming apps on your iPhone

Open the streaming app you want to use — YouTube, Netflix, Spotify, or another service that supports Chromecast. Start playing the video or audio you want to watch or listen to. Look for the cast icon, which looks like a rectangle with three curved lines in the bottom-right corner. It is usually white or colored, depending on the app.

Tap the cast icon. A menu will appear showing available devices. Select your Chromecast TV from the list. The content will when ready start playing on your television. Your iPhone screen will show playback controls — pause, play, volume, and a progress bar — so you can control what is happening on the TV without leaving the app.

While content is casting, you can use your iPhone for other things. You can browse the web, check email, or open another app. The video or audio continues playing on your TV. To stop casting, tap the cast icon again and select "Disconnect" or straightforward close the app.

Which apps work with Chromecast on iPhone

Major streaming services support Chromecast casting on iPhone. YouTube, YouTube Music, Netflix, Disney+, Hulu, HBO Max, Amazon Prime Video, Spotify, Apple Music, Google Play Music, and Pandora all have the cast icon built in. Many other apps do as well — news apps, fitness apps, and podcast services often include casting support.

The easiest way to check if an app supports Chromecast is to open it, start playing something, and look for the cast icon. If you do not see it, that app does not support casting to Chromecast. Some apps may require you to be a paid subscriber or to be logged in before the cast icon appears.

Troubleshooting casting problems

If the cast icon does not appear in your app, first check that your iPhone and Chromecast are on the same Wi-Fi network. They must be connected to the same network — if your iPhone is on your home network and your Chromecast is on a guest network, they cannot communicate. Restart both devices: unplug your Chromecast for 30 seconds, then plug it back in. Restart your iPhone by powering it off and on again.

If your Chromecast does not appear in the app's device list, open the Google Home app and confirm that your Chromecast is showing as connected. If it is not, remove it from Google Home and set it up again. Make sure your Chromecast firmware is up to date — the Google Home app will notify you if an update is available.

If casting starts but stops after a few seconds, check your Wi-Fi signal strength. Chromecast needs a stable connection. Move your Chromecast closer to your router or reduce interference from other devices. If the problem persists, restart your router by unplugging it for 30 seconds.

Casting audio only to your TV or speakers

You can cast music and podcasts to a Chromecast device connected to speakers or a soundbar, not just to a TV. Open Spotify, Apple Music, Pandora, or another audio app, start playing something, tap the cast icon, and select your Chromecast device. The audio plays through your speakers while you control it from your phone.

This works the same way as video casting. You can browse other apps on your iPhone while music plays on your speakers. To stop, tap the cast icon and disconnect.

What you cannot do with Chromecast on iPhone

Chromecast on iPhone does not support screen mirroring. You cannot broadcast your entire iPhone screen, your home screen, or your browser tabs to your TV. If you need to mirror your whole screen, you would need to use AirPlay instead, which requires an Apple TV device.

You also cannot cast content that is protected by copyright restrictions or digital rights management. Some apps may block casting for certain content, even if the app itself supports Chromecast. This is a limitation built into the app or the content provider, not Chromecast itself.

Frequently Asked Questions

Can I cast from Safari or Chrome browser on my iPhone?

No. Safari and Chrome on iPhone do not support casting to Chromecast. You can only cast from apps that have built-in Chromecast support. If you want to watch web content on your TV, open it in a compatible app instead — for example, YouTube videos through the YouTube app rather than through Safari.

What if my Chromecast is on a different Wi-Fi network than my iPhone?

Casting will not work. Your iPhone and Chromecast must be on the same Wi-Fi network to communicate. Connect both devices to the same network and try again. If you have a guest network, make sure both are on your main home network, not the guest network.

Can I cast to multiple Chromecast devices at the same time from my iPhone?

Most apps allow you to cast to only one device at a time. Some apps may support multi-room audio or video, but this is rare on iPhone. Check your app's settings to see if this feature is available.

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

No. Once casting starts, your Chromecast streams directly from the internet to your TV. Your iPhone is just sending commands and controlling playback, which uses very little data. You can even turn off your iPhone's screen and it will not interrupt the cast.

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

The app may not support Chromecast, you may not be logged in, or you may need to update the app. Try logging out and back in, or delete and reinstall the app. If the cast icon still does not appear, that app does not support Chromecast on iPhone.
