GCast lets two phones share one screen, so you and a friend can play side by side even when you aren't in the same room. Cast from your iPhone, hand half the screen to someone else, and play. What you can do: - Cast your iPhone to another iPhone or iPad. - Share that screen with a friend so two games run side by side. - Create a private room with a short code and send the link. - Get a pop-up the moment a guest asks to join, so you don't miss anyone. - Pick a nickname and a pixel-art avatar instead of being a random string of characters. - Play over the internet, not just Wi-Fi. - Built on WebRTC, so the lag stays low enough to actually play through. Works for couch co-op, late-night online sessions, watch parties, and whatever else. TURBO is an optional auto-renewable subscription that unlocks casting up to 1080p (native resolution) and removes the on-screen watermark, available monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase; the subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://gcast.app/privacy
