Chromecast works with iPhone, but only for certain apps and tasks

Yes, Chromecast works with iPhone. You can cast video, music, photos, and web content from your iPhone to a TV connected to a Chromecast device. However, iPhone does not support the same casting method that Android phones use. Instead of mirroring your entire screen, you cast individual apps and content through built-in casting features or third-party apps that support Chromecast.

The limitation matters because you cannot mirror your iPhone's full screen to Chromecast the way you can with an Android phone. What you can do is send specific content — a YouTube video, a Spotify playlist, photos from your library, or a web page — directly to your TV through apps that have Chromecast built in.

Key Takeaways

  • iPhone can cast to Chromecast through apps that support it, such as YouTube, Netflix, Spotify, and Google Photos, but full-screen mirroring is not available.
  • You need the Google Home app installed on your iPhone to set up and manage your Chromecast device.
  • Casting from iPhone requires your phone and Chromecast to be on the same Wi-Fi network.
  • Some apps like Plex, Hulu, and Disney+ support Chromecast on iPhone, while others do not.

Which apps on iPhone support Chromecast

Major streaming services built Chromecast support into their iPhone apps. YouTube, Netflix, Disney+, Hulu, HBO Max, Spotify, Apple Music, Google Play Music, Pandora, and Plex all let you cast to Chromecast from iPhone. Google Photos, Google Drive, and Chrome browser also support casting. When you open one of these apps, look for a cast icon — usually a rectangle with curved lines in the corner — and tap it to send content to your Chromecast device.

Not every app supports Chromecast. Apple TV+, for example, does not have a cast button in its iPhone app. If an app does not show a cast icon, you cannot send content from that app to Chromecast. Check the app's settings or help section to confirm whether casting is supported before you buy a subscription or assume you can use it with your TV.

How to set up Chromecast on your iPhone

read the Google Home app from the App Store and open it. Tap the plus icon in the top left corner and select "Set up device." Choose "Set up a new device" and follow the on-screen steps. The app will ask you to select your home Wi-Fi network and enter your password. Make sure your iPhone is on the same network as your Chromecast device — they must be connected to the same router.

Once setup is complete, your Chromecast device will appear in the Google Home app. You can rename it, adjust settings, and see which apps are casting to it. If you have multiple Chromecast devices in your home, each one will show up separately in the app so you can choose which TV to cast to.

Screen mirroring from iPhone to Chromecast is not possible

Unlike Android phones, iPhones cannot mirror their entire screen to Chromecast. Apple does not allow third-party screen mirroring to Chromecast through its operating system. If you need to show your iPhone screen on a TV, you have two alternatives: use AirPlay to an Apple TV device instead, or cast individual apps that support Chromecast.

This is a hard limit. No workaround, app, or setting will enable full-screen mirroring from iPhone to Chromecast. If full-screen mirroring is essential for your use case — such as presenting a slide deck or showing a document — you will need an Apple TV device or a different casting method.

Casting web pages from Chrome browser on iPhone

Google Chrome on iPhone supports casting to Chromecast. Open Chrome, navigate to the web page you want to cast, tap the three-dot menu icon, and select "Cast." Choose your Chromecast device from the list. The page will appear on your TV, and you can continue browsing on your iPhone while the page displays on the larger screen.

Casting a web page works well for showing photos, articles, or video content hosted on a website. However, not all interactive features may work the same way on the TV as they do on your phone. Test casting before you rely on it for something important, such as a presentation or a live event.

Wi-Fi network requirements and troubleshooting

Your iPhone and Chromecast must be on the same Wi-Fi network to cast. If you are on a guest network or a different band of your router (2.4 GHz versus 5 GHz), casting will not work. Check your phone's Wi-Fi settings and your Chromecast settings in the Google Home app to confirm both are connected to the same network name.

If casting fails, restart your iPhone, restart your Chromecast device by unplugging it for 10 seconds, and try again. If the cast icon does not appear in an app, close the app completely and reopen it. Clearing the cache in the Google Home app can also resolve connection issues — go to Settings, find Google Home, and select "Clear Cache."

Chromecast device options and compatibility

Google makes several Chromecast models: the standard Chromecast (a small disc that plugs into HDMI), Chromecast with Google TV (which includes a remote and an interface), and Chromecast Audio (for speakers). All of them work the same way with iPhone — through apps that support Chromecast and the Google Home app for setup. The main difference is what you see on your TV and how you control playback.

Chromecast with Google TV is the most versatile because it has its own interface and remote, so you can browse and launch apps directly on the TV without needing your phone. Standard Chromecast requires you to cast from your phone every time. Both work with iPhone equally well for casting supported apps.

Frequently Asked Questions

Can I mirror my iPhone screen to Chromecast?

No. Apple does not allow screen mirroring to Chromecast from iPhone. You can only cast individual apps and content that have built-in Chromecast support. If you need full-screen mirroring, use AirPlay with an Apple TV device instead.

Do I need a Google account to use Chromecast with iPhone?

Yes. You need a Google account to set up Chromecast through the Google Home app. The account is free to create if you do not already have one. You will use it to sign in to the Google Home app and manage your Chromecast device.

What if my app does not have a cast button?

If an app does not show a cast icon, it does not support Chromecast on iPhone. Check the app's settings or help documentation to confirm. Some apps may add Chromecast support in future updates, so check back periodically if you are waiting for a specific app.

Can I cast from iPhone while using cellular data instead of Wi-Fi?

No. Your iPhone and Chromecast must both be on the same Wi-Fi network. Cellular data on your phone will not work for casting. Both devices need to be connected to the same router or Wi-Fi network.

Will casting drain my iPhone battery quickly?

Casting uses Wi-Fi and some processing power, so your battery will drain faster than normal. The drain depends on what you are casting and for how long. Casting a video for an hour will use noticeably more battery than casting a static photo. Keep your charger nearby if you plan to cast for extended periods.
