Hey Product Hunt! 👋 Sparcam started as a side project literally called "shadow boxing" — I wanted cardio I'd actually stick with, without buying equipment or installing anything. What it is: cardio games your body controls through the webcam. 🥊 Boxing — punch the pads, slip the bars, chase the combo 🎾 Tennis — make a fist to grip the racket, swing to return the ball 🍉 Slicer — slice fruit with fast sweeps, duck the bombs How it works: on-device pose detection reads your body in real time, right in the browser tab. Real movement is what scores points — no gamepad, no wearables, nothing to hold. Privacy was non-negotiable: camera frames are analysed on your device and discarded immediately. Nothing is uploaded, stored or recorded — close the tab and it's gone. Is it a real workout? Yes. Timed rounds speed up as you land more, and a 90-second fitness test places you on the ladder. Free in early access — every game open, no credit card. All you need is a webcam and about two metres of space. I'd love to hear: which game feels best — and what game should we build next? Hands up! 🥊
