Hopmodo
Fitness-Pair
Your body is the controller. Hopmodo makes screen time active play: squat to cast spells, jump over obstacles, and do push-ups to fly. Play in your browser with just a webcam. Movement tracking stays on-device, and automatic replay clips let you relive and share each round.
Built with Astra
We used Astra in Codex to turn movement-game experiments into Hopmodo, a deployed browser arcade. Our team directed the gameplay; Astra helped carry the product through design, code, debugging, testing and release. It helped connect camera calibration, body landmarks and game actions, then built automatic local replays combining the camera, game, sound, score and branding. MediaPipe runs live body tracking on-device; Astra powered our build workflow. We iterated through feedback, code changes and browser checks. With Impeccable, Astra shaped the visual direction and responsive interface. Parallel agents handled artwork and independent review. Automated checks exercised game entry, completed rounds, replay playback and camera cleanup, while browser inspection checked desktop and mobile layouts. Astra helped our two-person team bring separate games into one cohesive experience: move, play, replay and share.
