ShapeSync - Health Coach - Nutrition, Training, Sleep

by•
ShapeSync reads Apple Health data from any app you use for tracking and turns it into a dashboard that explains what's happening with your weight. New since launch: an AI Coach giving active, dosage-level recommendations based on your real data — not generic tips. Plus real plateau detection with trend smoothing + goal-date projection, and Watch calorie-burn calibration. Metrics stay on your iPhone — no account, no cloud. Only AI Coach queries are sent, with consent, to power the analysis.

Hey Product Hunt 👋 I built ShapeSync because I was tired of weight-loss apps either requiring their own ecosystem (buy our watch, use our scale) or just showing me a noisy chart with no real insight into why my weight wasn't moving. The Apple Watch calibration feature came out of my own frustration — I noticed my Watch's calorie estimates never quite matched what my actual weight was doing, so I built something that compares the two and corrects for it. Happy to answer anything about the tech, the privacy approach (everything local, no account), or what's coming next. Thanks for checking it out!
