Your phone becomes the camera for Catch Flex. This app is the controller for Catch Flex, a full-body dance rhythm game you play on a TV, computer or console. You need the game to play. The app tracks your moves with your iPhone or iPad camera and sends them to the game over your Wi-Fi, so the game sees you from across the room. Slash blocks, catch rings, kick balls, stomp, slide and dodge to the beat with your whole body. Play a few songs back to back and it is a workout. HOW IT WORKS • Start Catch Flex on your TV, computer or console. • Open this app and tap the game when it shows up, or scan the QR code on the game's screen. • Prop your phone up, step back until your whole body is in frame, and play. WHAT YOU GET • Tracking with the front or the back camera, and the wide lens where your phone has one. • Two players on one phone: hold it sideways, and whoever stands on the left is player 1, the one on the right player 2. For the smoothest tracking, one phone per player is still best. • A live skeleton over the camera preview shows what the game sees. PRIVACY The game gets your pose as numbers, over your own network. Video never leaves your phone. No account, no ads.
