How to Stream PC Screen to Phone Browser (iPhone & Android Offline)

Many users search app stores for an Android APK or an iOS companion app when looking to stream their PC screen to a smartphone or tablet. With ScreenTask, you do not need to install any mobile app, plugin, or client software.

Because ScreenTask serves real-time video frames using standard HTTP and HTML5, any mobile device equipped with a modern web browser—such as Safari on iOS or Google Chrome on Android—can immediately stream your computer screen over your local network.

Why Stream PC Screen to Phone Browser (Without an App)?

Commercial screen mirroring tools like AirDroid, TeamViewer, or Splashtop often require downloading proprietary mobile apps, creating accounts, or purchasing monthly subscriptions. In contrast, streaming directly to a mobile browser provides distinct advantages:

Zero App Store Downloads: Viewers never need to install APK files or iOS apps that consume device storage or request intrusive device permissions.
Universal Cross-Platform Support: Works on iPhone (iOS Safari), Android smartphones (Chrome, Samsung Internet, Firefox), iPad, Android tablets, and smart TVs.
True Offline & Air-Gapped Operation: Stream inside vehicles, flights, classrooms, or campsites where there is no internet connection.
No Account or Sign-in Required: Connect directly to the host computer’s local IP address with optional password protection.

Step-by-Step: Stream PC Screen to Phone Browser

Step 1: Start Broadcasting on Your Windows PC

Download and run ScreenTask on your host PC (no installation required).
Under the IP drop-down, select your active local IPv4 address (e.g., 192.168.1.100 or 192.168.137.1 if using a mobile hotspot).
Confirm the port number (default is 7070 or 9000).
Set an optional password if you want a private viewing session.
Click Start Server.

Step 2: Ensure Both Devices Are on the Same Local Wi-Fi

Make sure your smartphone and your PC are connected to the same Wi-Fi router or the same mobile hotspot.

[!TIP] No Wi-Fi router available? Turn on your smartphone’s Personal Hotspot and connect your laptop to it, or enable Windows Mobile Hotspot on your PC. ScreenTask will broadcast seamlessly over the hotspot without consuming any cellular data.

Step 3: Open the Stream in Safari or Chrome

For Android Users (Google Chrome / Samsung Internet)

Open Google Chrome on your Android phone.
In the URL address bar, enter your PC’s IP and port:
```
http://192.168.1.100:7070
```
Tap Enter. If prompted, enter the session username and password.
Tip: Tap the Chrome menu (⋮) and select Add to Home screen to run ScreenTask borderless in full screen.

For iPhone & iPad Users (Apple Safari)

Open Safari on your iOS device.
Enter the host PC’s address in the Safari search/address bar:
```
http://192.168.1.100:7070
```
Tap Go. Enter your credentials if password protection is enabled.
Tip: Tap the Share button in Safari and choose Add to Home Screen for an instant app-like launcher.

Optimizing Mobile Streaming Performance

Rotate to Landscape: Viewing desktop displays in landscape orientation offers 100% aspect ratio alignment and crisp code/text legibility.
Adjust Refresh Rate for Mobile Wi-Fi: If you are streaming over crowded 2.4 GHz wireless networks, adjust ScreenTask’s refresh interval to 500 ms and quality to 70%.
Smart TVs & Whiteboards: You can also mirror your PC to smart TVs (LG webOS, Samsung Tizen, Android TV) simply by opening the TV’s native browser app and loading the ScreenTask address.

Frequently Asked Questions

Can viewers interact with or control my PC from the phone?

No. ScreenTask is built as a secure, view-only broadcast server. Mobile viewers cannot click, type, or access your files, keeping your computer protected during presentations and lectures.

What if my phone browser says “Cannot connect” or times out?

Ensure your PC’s network profile is set to Private and that Windows Defender Firewall is permitting incoming connections on port 7070 or 9000. See our Windows 11 Setup & Firewall Guide.
