Hatch Duo

Hatch Duo Move together, hatch an egg. A co-op fitness game — no install, your friends just scan a QR code. Hatch Duo turns "exercise you can't stick to alone" into a cooperative game with friends and family. ■ The egg only hatches when everyone finishes 2-4 players join a room, and each takes one move: squats, jumps, punches, or high knees. If even one person quits halfway, the egg won't hatch. That's why the moment it does, it belongs to all of you. ■ No install, no sign-up It runs in the browser. Whoever you invite just opens a link — no download, no account. ■ No camera needed Just hold your phone and move. The accelerometer counts your reps. Sensor data is processed on your device and never sent anywhere. ■ Different days are fine You finish today, your partner finishes tomorrow — the egg still hatches. No need to sync schedules. ■ Raise them and keep the record Every hatched buddy…
