Casting from iPhone to Chromecast requires a workaround because Apple and Google don't natively support the connection

Your iPhone cannot cast directly to a Chromecast device the way an Android phone can. Apple's ecosystem uses AirPlay, while Chromecast uses Google Cast—they don't speak the same language. However, you have three practical routes: use an app that bridges the gap, mirror your entire screen through a third-party tool, or cast through a web browser on your phone.

The most reliable method for most people is using an app designed to work with both systems. Google's own YouTube app, for example, lets you cast videos directly from iPhone to Chromecast. Netflix, Disney+, Spotify, and many other streaming services also support casting from iPhone. If the app you want to use has a cast button (usually a rectangle with a WiFi symbol in the corner), tap it and select your Chromecast device—that's the simplest path.

Key Takeaways

  • Apps like YouTube, Netflix, and Spotify have built-in cast buttons that work directly from iPhone to Chromecast without extra tools.
  • Your iPhone and Chromecast must be on the same WiFi network for any casting method to work.
  • Screen mirroring apps like Replica or AirBeamTV let you cast your entire iPhone screen, but they require a small fee or subscription.
  • Casting through a web browser works for websites that support Chromecast, like YouTube.com or Spotify Web Player.
  • If casting fails, restart both your iPhone and Chromecast device, then check that they're connected to the same WiFi network.

Using built-in cast buttons in streaming apps

Most major streaming services added cast support specifically because so many iPhone users wanted this feature. Open the app, start playing a video or song, and look for the cast icon—it looks like a small rectangle with a curved WiFi symbol in the bottom right or top right corner of the playback screen.

Tap that icon and your iPhone will scan for nearby Chromecast devices on your WiFi network. Select the device you want to cast to, and playback will move to your TV or speaker within a few seconds. The app will show you that casting is active, usually with the cast icon highlighted or a banner at the top of the screen. You can then lock your iPhone, switch apps, or even turn off the screen—the content keeps playing on your Chromecast.

This method works with YouTube, YouTube Music, Netflix, Disney+, Hulu, HBO Max, Spotify, Google Play Music, Pandora, and dozens of other services. Check the app's settings or help section if you don't see a cast button—some apps hide it in a menu or require you to be playing content first.

Screen mirroring your entire iPhone display

If the app you want to use doesn't have a built-in cast button, you can mirror your whole screen to Chromecast using a third-party app. Apps like Replica, AirBeamTV, and Streamer for Chromecast create a bridge between your iPhone and Chromecast. These apps typically cost between $5 and $15 or work on a subscription model.

read and open one of these apps, make sure your iPhone and Chromecast are on the same WiFi network, then tap the button to start mirroring. Your entire iPhone screen will appear on your TV with a slight delay—usually one to three seconds. This works for any app on your phone, including ones that don't officially support casting, but the delay makes it less smooth than native casting for video playback.

The trade-off is worth it if you regularly need to cast from an app that has no other option. Keep in mind that mirroring uses more battery and WiFi bandwidth than direct casting, so your iPhone may get warm during extended use.

Casting through a web browser

If you're trying to cast a website rather than an app, open Safari or Chrome on your iPhone and navigate to the site. Many websites, including YouTube.com, Spotify Web Player, and others, have their own cast buttons built into the web version.

Tap the cast icon on the website itself (not your phone's browser controls), select your Chromecast device, and the content will stream to your TV. This method works well for YouTube, Spotify, and other services that maintain full-featured web players. The experience is nearly identical to casting from the native app.

Checking your WiFi connection and device setup

Before troubleshooting, confirm that your iPhone and Chromecast are truly on the same network. Open Settings on your iPhone, tap WiFi, and note which network you're connected to. Then check your Chromecast by opening the Google Home app on your iPhone, tapping the device, and looking at the network name listed under "Device information."

If they're on different networks—for example, if your Chromecast is on your 5GHz band and your iPhone is on 2.4GHz—they won't see each other. Most modern routers broadcast both bands under the same name, but some split them. If you see two network names in your WiFi list, try connecting your iPhone to the same band your Chromecast is using.

Also check that your Chromecast is powered on and has finished its startup sequence. The device should show a solid light or display a screensaver. If it's blinking or showing a setup screen, complete the setup in the Google Home app first.

Restarting devices when casting won't work

If you've confirmed both devices are on the same network but casting still fails, restart both. Unplug your Chromecast from power, wait 10 seconds, and plug it back in. While it's restarting, restart your iPhone by holding the side button and volume button, sliding to power off, waiting a few seconds, then powering back on.

Once both devices have fully restarted, open your streaming app again and try casting. This clears temporary connection issues that often prevent discovery. If you're still having trouble, try "forgetting" the WiFi network on your iPhone (Settings > WiFi, tap the network name, tap "Forget"), then reconnect by selecting it again and entering the password.

Casting audio only to Chromecast speakers

If you have a Chromecast Audio device or a Chromecast built into a speaker, you can cast music and podcasts from your iPhone the same way you cast video. Open Spotify, Apple Music, Podcasts, or another audio app, tap the cast icon, and select your speaker device. The audio will play through your speaker while your iPhone screen can lock or run other apps.

Audio casting is often more reliable than video casting because it uses less bandwidth. If video casting is choppy but you want to test your connection, try casting audio first to confirm your network is working properly.

Frequently Asked Questions

Why doesn't my iPhone show a cast button in my app?

Not all apps support casting, and some hide the cast button in a menu. Check the app's settings or help section. If it's not there, the app doesn't support Chromecast—you'll need to use screen mirroring or a web browser instead.

Can I cast from iPhone to a Chromecast on a different WiFi network?

No. Your iPhone and Chromecast must be on the same WiFi network to communicate. If you're at a location with multiple networks, connect both devices to the same one.

Does casting drain my iPhone battery faster?

Casting uses more power than normal use because your phone is actively streaming data. Direct casting (using app cast buttons) uses less battery than screen mirroring. If battery is a concern, plug your iPhone in while casting.

Can I use my iPhone while casting?

Yes, with direct casting. When you cast from an app using its cast button, you can lock your screen, switch apps, or even turn off your phone—the content keeps playing on your Chromecast. With screen mirroring, your entire display is being sent, so anything you do on your phone appears on the TV.

What if my Chromecast isn't showing up in the cast menu?

Make sure both devices are on the same WiFi network, your Chromecast is powered on and finished starting up, and your iPhone's WiFi is turned on. Restart both devices, then try again. If it still doesn't appear, restart your WiFi router.
