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 play split screen online with friends on GCast?

Switch to Party mode in GCast, share the room code or QR with your friend, accept their join request, and tap Cast. Both phones land side by side on the screen, no matter where each player is.

Does my friend need to be on the same WiFi to join my GCast room?

No. Party mode works over the internet. Your friend can join from anywhere using the room code or QR link. The same flow also works locally if you happen to be in the same room.

How does my friend join my GCast Party room?

Tap Invite friends to get a room code, share link, or QR code. When your friend opens it, they appear in your room as a pending challenger and you accept them in.

Can I kick someone out of my GCast room?

Yes. As the host you can remove any player from the People in this room list at any time.

What is the difference between Solo and Party mode in GCast?

Solo mode mirrors your single phone to a screen. Party mode creates a shared room where multiple players cast at once, side by side, whether they are sitting next to you or playing from another city.

How to Play Split Screen With Friends, Anywhere

Remember Mario Kart on the couch? Four controllers, one CRT, snacks everywhere. That feeling never really left, it just moved. Now your squad lives in five different cities, your "couch" is a Discord call, and the game is Fortnite, PUBG, or Brawl Stars.

Split screen still works for both. GCast Party mode lets you play side by side with friends in the same room, or with friends a thousand miles away, using the exact same flow.

One Flow, Two Vibes

Whether you are passing controllers around the living room or jumping into a Brawl Stars duo from across the country, GCast Party works the same way. You spin up a room, share the code, your friend joins, you cast. The big screen shows both players side by side either way.

How to Set Up a GCast Party

Step 1: Open GCast and switch to Party mode

Open GCast and tap the Party tab at the top. Solo mode mirrors a single phone to your screen. Party mode creates a shared room where multiple 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 the key your friends use to join you.

Step 3: Invite friends

Tap Invite friends to open the share sheet. You can send the room link directly through any chat app, copy the code, or have a friend in the room scan the QR. Same code works for everyone.

Step 4: Friend opens the invite

Your friend taps the link or scans the QR. They land in a "Waiting for admission" screen on their phone or tablet. Their name shows up in your room as Pending.

Step 5: Accept the new challenger

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

For longer sessions, pair a Bluetooth gamepad to your phone. Anyone in the room can do this independently, and any game that supports controllers will pick it up.

Where Party Mode Shines

Squad up in PUBG with friends across the country

Your PUBG squad doesn't live on the same block anymore, but rotations and callouts still need to land. Drop a room code in the group chat, hop on Discord, and watch each other's angles in real time. Spotting a flank on your teammate's half of the screen hits different when you are reacting to it instead of just hearing about it.

Brawl Stars duos that actually feel coordinated

Co-op shines when you can see what your partner sees. Party mode puts both Brawl Stars perspectives on one screen so pushes, baits, and Super timing turn from guesswork into plays. Showdown duos suddenly feel like a real team sport.

Couch chaos with Stumble Guys

Same room, same vibe as console split screen. Two phones, one TV, three rounds of Stumble Guys before someone rage quits. Perfect for a Friday night with friends or a quick round with the kids before dinner.

Watch a friend's run while you play yours

Speedrunning, learning a new game, or just hyped about what your friend is doing? Side by side casting means you do not have to choose between playing and watching.

Family game time across distance

Cousins in another country. Grandparents on the other coast. Party mode turns mobile games into something you do together, not separately.

Capture the Best Moments and Share Them

The clutch 1v3, the impossible Showdown win, the Stumble Guys ragdoll moment that made everyone scream. Split screen sessions are full of clips worth saving. Record straight from your screen, post to TikTok, Instagram Reels, X, or your group chat, and let the whole internet enjoy what you and your friends just pulled off.

Tips for the Best Party Experience

Solid WiFi on both ends keeps streams smooth, especially for remote players
Drop a Discord or FaceTime call alongside it so trash talk and callouts work like they should
Use gamepads for longer sessions, each player pairs their own
Host can remove players from the People in this room list if needed
One room code, share it freely anyone with the link can request to join, you decide who gets in

Ready to Squad Up?

Open GCast, switch to Party mode, send the room code to your friends. Whether they are sitting next to you or across the world, you'll be playing split screen together in under a minute.
