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?

Open GCast and switch to Party mode. A room code appears at the top. Read the code to the second player, they enter it on their phone, you accept them in, then tap Cast. Both phones appear side by side on the screen.

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

Yes. In Party mode, each player runs their own game on their own phone. Both games are displayed side by side on the screen simultaneously.

Do I need two phones for GCast split screen?

Yes. Each player needs their own phone with GCast installed. For local play in the same room, both phones can simply join the same Party room over the same WiFi.

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 decides who joins the room?

The host, meaning the first person who created the Party room, accepts or declines anyone who tries to join using the room code.

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 in the same room.

How to Set Up Split Screen

Step 1: Open GCast and switch to Party mode

Open GCast on the first player's phone and tap the Party tab at the top. Solo mode mirrors a single phone to your screen. Party mode creates a shared room where two (or more) players cast together.

Step 2: Get your room code

The moment you switch to Party, GCast spins up a fresh room with a unique code (like `I3HWK2D8`). This is what Player 2 uses to join you.

Step 3: Share the code with Player 2

Sitting on the same couch? Just read the code out loud. You can also tap Invite friends and have them scan the QR for an instant join. The room works the same whether Player 2 is next to you or across the country, but for local play the simplest path is just reading the code.

Step 4: Player 2 requests to join

Player 2 opens GCast, taps Party, enters the room code (or scans the QR). They land on a "Waiting for admission" screen on their phone or tablet, and their name shows up in your room as Pending.

Step 5: Accept Player 2

You get a "Here's a new challenger!" prompt with their name. Tap Accept and they join the room.

Step 6: Cast and play together

Once both players are in, tap Cast. Both phones land side by side on the big screen. Open your games and you are off.

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
