How to Stream Your iPhone to Roku

Guide 10-37814 · Updated · Step by step

Streaming from your iPhone to a Roku lets you watch your photos, videos, and apps on the big screen without buying extra cables or hardware. You can mirror your entire screen or send specific videos, music, and photos directly to the TV. Before you start, make sure your iPhone and Roku are on the same Wi-Fi network, and that both devices have the latest software updates installed.

What You’ll Need

  • An iPhone (any model running iOS 12 or later, though newer versions work best)
  • A Roku streaming device or Roku TV (2017 models or newer for screen mirroring)
  • Both devices connected to the same Wi-Fi network
  • The Roku mobile app (free, from the App Store) for some methods

Step-by-Step

Method 1: Screen Mirroring (for Everything on Your Screen)

  1. Enable screen mirroring on your Roku: Go to Settings > System > Screen mirroring and set it to Prompt or Always allow. If you choose Prompt, you’ll need to confirm each time you connect.
  2. Open Control Center on your iPhone: Swipe down from the top-right corner (on iPhones with Face ID) or swipe up from the bottom edge (on iPhones with a Home button).
  3. Tap the Screen Mirroring icon: It looks like two overlapping rectangles. A list of available devices will appear.
  4. Select your Roku device: Tap the name of your Roku (e.g., “Living Room Roku”). If prompted, enter the code that appears on your TV screen.
  5. Wait for the connection: Your iPhone screen should appear on the TV within a few seconds. You can now rotate your phone to change orientation, and everything you do on the phone will be mirrored.
  6. Stop mirroring: Open Control Center again, tap Screen Mirroring, and tap Stop Mirroring.

Method 2: Using the Roku Mobile App (for Photos, Videos, and Music)

  1. Install the Roku app: Download the official Roku app from the App Store if you haven’t already.
  2. Connect to your Roku: Open the app and tap Devices at the bottom. Your Roku should appear if both are on the same network. Tap it to connect.
  3. Tap the Media tab: In the app, you’ll see options like Remote, Channels, and Media. Tap Media.
  4. Choose what to cast: You can select Photos, Videos, or Music. The app will access your iPhone’s library.
  5. Select a file and play: Tap a photo or video, and it will start playing on your Roku. For music, you can create a playlist and play it on the TV.
  6. Control playback: Use the app as a remote to pause, rewind, or adjust volume.

Method 3: Casting from Supported Apps (Netflix, YouTube, etc.)

  1. Open a video app: Launch an app that supports casting, such as YouTube, Netflix, Hulu, or Disney+.
  2. Start playing a video: Play any video.
  3. Tap the Cast icon: Look for a rectangle with a Wi-Fi symbol in the corner (usually top-right). Tap it.
  4. Select your Roku: Choose your Roku from the list of available devices.
  5. Watch and control: The video will play on the TV, and you can use your phone as a remote. You can even browse other apps on your phone while the video plays.

Common Mistakes

  • Not being on the same Wi-Fi network: This is the most common issue. Both devices must be on the exact same network (same band, e.g., 2.4GHz or 5GHz) for any method to work.
  • Screen mirroring not enabled: On some Roku models, screen mirroring is off by default. If you don’t see your Roku in the Screen Mirroring list, go to Roku settings and enable it.
  • Using an old Roku: Screen mirroring requires a Roku that supports it (most models from 2017 onward). Older models may not have the option.
  • Forgetting to update: Outdated software on either device can cause connection failures. Check for updates in Roku settings and in iOS Settings > General > Software Update.
  • Expecting audio to always work: When mirroring, audio should work, but some apps may block audio or have sync issues. Try using the Roku app for media files if you experience problems.

Tips

  • Use 5GHz Wi-Fi: If your router supports it, connect both devices to the 5GHz band for a more stable connection and less lag.
  • Keep your iPhone close: While not required, being closer to the router or Roku can improve performance.
  • Use AirPlay if supported: Many newer Roku models support Apple AirPlay 2 natively. If your Roku has AirPlay, you can use the same Control Center method but select AirPlay instead of Screen Mirroring. This often works better for video apps.
  • Turn off Bluetooth: If you have Bluetooth devices connected to your iPhone, it can sometimes interfere with Wi-Fi. Turn off Bluetooth if you’re having trouble.
  • Restart both devices: If you’re having issues, a simple restart of your iPhone and Roku can clear up most problems.

Troubleshooting

I don’t see my Roku in the Screen Mirroring list. First, ensure screen mirroring is enabled on your Roku (Settings > System > Screen mirroring). If it is, try restarting both devices. Also, check that both are on the same Wi-Fi network—if you have a dual-band router, try connecting both to the 2.4GHz band.

The connection keeps dropping. This is usually a Wi-Fi signal issue. Move your Roku and iPhone closer to your router, or consider using a wired Ethernet connection for your Roku (if it has an Ethernet port). Also, make sure there aren’t too many devices using the network.

Video plays but there’s no sound. Check the volume on both your iPhone and your TV. Some apps may have separate audio controls. If you’re mirroring, try using the Roku app to cast a video instead—it often handles audio better.

Screen mirroring is very laggy. This is common, especially with games or fast-moving video. Try closing other apps on your iPhone to free up resources. Also, ensure you’re not too far from the router.

I can’t find the Media tab in the Roku app. Make sure you’ve updated the Roku app to the latest version. The Media tab may be hidden if you haven’t connected to a device yet.

Frequently Asked Questions

Can I stream Netflix from my iPhone to Roku?

Yes, use the Cast icon inside the Netflix app. Select your Roku from the list, and the show will play on TV. You can also use AirPlay if your Roku supports it.

Does screen mirroring work with all apps?

Most apps will mirror, but some (especially streaming services) may block screen mirroring due to copyright. In those cases, use the app’s built-in Cast feature instead.

Can I use my iPhone as a remote for Roku?

Yes, the Roku mobile app includes a remote feature. It also lets you use your keyboard to type, which is handy for search.

Why is there a delay between audio and video?

Audio lag can happen when mirroring. Try using the Roku app to cast media, or use AirPlay if available. Adjusting the audio sync in your TV’s settings can also help.

Will screen mirroring drain my iPhone battery?

Yes, mirroring uses a lot of power. Keep your phone plugged in if you plan to watch for a long time.

Can I mirror my iPhone to Roku without Wi-Fi?

No, both methods (screen mirroring and the Roku app) require a Wi-Fi network. There’s no direct cable or Bluetooth option for iPhone-to-Roku.
