Hey Product Hunt 👋 I built FormCoach because bad form is the #1 reason people get hurt or plateau in the gym — and a personal trainer costs $60+/session. I wanted that "fix your knees" feedback for everyone, without sending workout videos to a server. How it works - 📹 Point your iPhone at yourself and start a set - 🧠 On-device AI (Apple Vision) measures your joint angles in real-time — knee valgus, spine alignment, squat depth - 🔢 Every set gets a 0–100 form score, so you can actually track if you're improving - 🗣️ Voice coaching corrects you mid-rep ("keep your back straight") — no need to look at the screen - 🎧 Hands-free: just say "next set", "pause", or "stop" (great with AirPods, hands on the bar) The part I care about most: privacy. Everything runs on-device with Apple's Vision + Speech frameworks. Your camera feed and your voice never leave your iPhone. No accounts, no cloud, no upload. Today it coaches 5 movements — squat, push-up, lunge, deadlift, overhead press — with trends, streaks, and personal records on top. It's free to start (squat & push-up), and Pro unlocks all exercises,unlimited sets, and long-term trend analysis with a 7-day free trial. Would love your feedback — especially: which exercise should I add next? 🙏 https://apps.apple.com/us/app/fo...
