KDNCE is a running coach designed exclusively for Apple Watch and iPhone. No overwhelming dashboards. No social feeds. Just clean, science-backed training that adapts to how your body feels today. Your Apple Watch already tracks your heart rate, HRV, VO2 max, and sleep. KDNCE uses that data to build personalized training plans, adjust your paces in real time, and tell you when to push hard and when to rest. WHAT YOU GET • Adaptive training plans that respond to missed workouts, fatigue, and readiness • Real-time pace coaching with haptic alerts on your Watch • Live stamina gauge so you never bonk • Running dynamics — cadence, ground contact time, stride length • Daily readiness score from your sleep, HRV, and resting heart rate • Race predictions for 5K, 10K, Half Marathon, and Marathon • Training load balance to avoid overtraining and injury • Recovery time estimates after every workout • Energy score that tracks your body battery throughout the day • Smart taper plans for race day • Shoe mileage tracking with replacement alerts THE SCIENCE Built on the Jack Daniels VDOT model — the same system used by Olympic coaches to set training paces. Your zones, paces, and race predictions are derived from your actual VO2 max, not generic formulas. YOUR DATA STAYS YOURS No account required. No cloud. No tracking. Everything runs on-device using Apple HealthKit. Your health data never leaves your phone or watch.
