ShapeSync - Nutrition, Training, Sleep

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 PH 👋 I first launched ShapeSync here in July — back then it was basically "PrivateJourney," a tool I built for myself while trying to lose weight and actually understand my own Apple Health data instead of staring at disconnected numbers. Since then the biggest gap has been closed: ShapeSync now has an AI Coach that gives active, dosage-level recommendations based on your real data — not generic "eat less, move more" tips. Combined with real plateau detection (trend smoothing + goal-date projection) and a calibration that corrects Apple Watch's known calorie-burn inaccuracy using your actual weight trend, it finally does what I originally wanted: turn tracking into understanding. It's a solo project — no team, no funding, just me building the thing I wished existed. What I'm genuinely unsure about: is "connecting the dots between your health data" something people actually care about, or is tracking-plus-a-chatbot enough for most? Would love to hear if this resonates, or if I'm solving a problem only I have.
