Install the app, tap cast, and your game appears on any screen. Your phone becomes the controller, and you can add overlays or AI companions.

Is this cloud gaming?

No. GCast uses your phone to run the game locally. That's why latency is ultra-low and costs stay minimal.

Do I need a console or special hardware?

No. Just your phone, WiFi, and a screen (TV, laptop, tablet).

Does GCast work with any game?

Yes. If it runs on your phone, it casts.

Casting is 100% free while in beta. After beta, basic casting will remain free and unlimited access will be part of a paid plan.

All gameplay data stays on your device; we don't sell or share it.

How do I use split screen on GCast?

Connect to your screen with GCast, tap Splitscreen in the experience picker, then have the second player open GCast on their phone and tap Cast. Both screens appear side by side.

Can two players play different games on one screen with GCast?

Do I need two phones for GCast split screen?

Yes. Each player needs their own phone with GCast installed. Both phones must be connected to the same WiFi network as the screen.

Can I use a gamepad with GCast split screen?

Yes. Each player can pair a Bluetooth gamepad to their phone. This works for any game that supports controller input.

Who can switch between Cast and Splitscreen mode?

Only the host, meaning the first person who connected to the screen, can switch between Cast and Splitscreen mode.

How to Use Local Split Screen with GCast

Remember split screen on consoles? Our afternoons spent playing Mario Kart, Super Smash Bros., and other classic games! GCast brings back that feeling, but with your phones. No console needed. Here's how to set it up.

How to Set Up Split Screen

Step 1: Start casting

Open GCast on the first player's phone and connect to your screen (TV or laptop). You'll start in the default Cast mode, which mirrors a single phone to the screen.

Step 2: Switch to Splitscreen mode

Tap Splitscreen to switch modes. This tells GCast to divide the screen into two halves, one for each player. Only the host (the first person who connected) can switch modes.

Step 3: Wait for Player 2

Once Splitscreen is active, the screen shows a "Waiting for Player 2..." prompt on the bottom half. The top half continues showing the host's screen. Now it's time for the second player to join.

Step 4: Player 2 joins

The second player opens GCast on their phone, sees the same screen in the device list, and taps Cast. Their phone screen instantly appears on the bottom half. Both players are now live.

Step 5: Play together

Both players open their game and start playing. Each person controls their own game on their own phone while watching the action unfold side by side on the big screen.

You can also use Bluetooth gamepads for games that support controllers. Each player pairs a gamepad to their phone and plays with physical controls, just like a console setup but running entirely from your phones.

Use Cases for Split Screen

Couch co-op with friends

Play competitive games like Brawl Stars head-to-head, or team up in co-op games like Minecraft with both screens visible at a glance.

Game night with the family

Turn any mobile game into a shared living room experience. Kids can play Roblox side by side, or the whole family can take turns in Stumble Guys with everyone watching.

Travel and hotel rooms

Stuck in a hotel with one screen? Two phones and GCast turn it into a multiplayer gaming setup. No console to pack, no special cables. Just connect to the hotel WiFi.

Competitive practice

Want to compare strategies in real time? Split screen lets two players see each other's screens simultaneously. Great for coaching or analyzing gameplay together.

Tips for the Best Split Screen Experience

Use 5GHz WiFi for smoother streaming from both phones
Keep both phones charged since casting and gaming together drains battery fast
Sit where you can see the screen clearly because each half is smaller than full-screen casting
Use gamepads if your games support them for more comfort during long sessions

Ready to Try?

Download GCast on two phones, connect to the same screen, and switch to Splitscreen mode. You'll be playing side by side in under a minute.
