Quick rundown of what's inside KinetFit: 🧪 Fitness age test — 10 tests → one number + your percentile vs. peers 🔁 Test → train → retest — train by recovery, retest, watch the number drop 🏋️ 1300+ exercise library — every move with step-by-step form cues 🤖 On-device AI plans — weekly plans matched from the library, tuned to your recovery 📸 Photo calorie recognition — snap a meal, get calories + protein back (dedicated vision model) 🔒 On-device, offline, 0 uploads — no servers, no accounts Built for 30–50-year-olds who want to know how their body's actually doing but aren't "fitness people" — and don't want their weight, heart rate, and sleep on someone's server. Happy to answer questions on the fitness-age methodology or the on-device model tradeoff! 🙏
