That $30/month recovery wearable you've been considering? You already own something better. Supernormal turns your Apple Watch into a full recovery intelligence system. Seven proprietary algorithms built on decades of clinical research in HRV, sleep science, and circadian biology. A live energy budget that updates every hour. No additional device. No guesswork. Every morning you wake up with a Biological Reserve โ€” a personalized energy budget built from how well you recovered overnight. Unlike a static morning score, it updates every hour. Supernormal tracks what you spend, what you earn back, and tells you exactly what to do next. Meet Norm. Your always-on biological intelligence. Watches your five body signals 24/7 and only speaks when something is worth knowing. Always watching. Never noise. Over 14 nights Supernormal builds a baseline that is entirely yours. Not population averages. Your normal. Every night more accurate. Every morning more personal. No account. No servers. Your health data never leaves your device. โ€”โ€” BIOLOGICAL RESERVE Unlike a static morning score, your Reserve depletes in real time as you train and move โ€” and earns back when you rest. Overdraft today and tomorrow pays for it. NORM Merges notifications, insights, post-workout coaching, and body intelligence into one unified feed. No dashboards. Just Norm, speaking up when something matters. BIOLOGICAL SIGNAL CLASSIFIER Five signals. Six named states โ€” adapting, nominal, sleep debt, accumulated fatigue, sustained stress, unusual body stress. Flags unusual patterns often 12-24 hours before you feel anything. RECOVERY SCORE HRV, resting heart rate, respiratory rate, and sleep quality into one personalized morning score. Your baseline. Your recovery. Not population averages. DAILY COACHING Every morning: a best move, a guardrail, and a preview of tomorrow. Smart notifications after workouts, when stress spikes, when to wind down. Not data. Decisions. SLEEP INTELLIGENCE Scored across duration, efficiency, deep sleep, and REM with running sleep debt tracking. 7 hours of broken sleep is not 7 hours of recovery. BIOLOGICAL PACE VO2 Max, HRV, resting heart rate, and deep sleep against age and sex-matched norms. One multiplier. 0.82x means your biology runs younger than your birth year. AUTONOMIC STRESS Live stress indicator based on HRV vs your morning baseline. Shifts green to amber in real time. STRAIN TRACKING Total cardiovascular load all day. Distinguishes sustained cardio from fragmented elevated heart rate. Not all strain is equal. DAILY JOURNAL Log in three taps. After 30 days Supernormal surfaces what your habits actually do to your recovery. INTELLIGENT NOTIFICATIONS 23+ smart alerts with individual cooldowns. Morning brief. Post-workout coaching. Sleep debt. Stress detected. Weekly report. PRIVACY FIRST No account. No servers. Health data never leaves your device. Optional iCloud sync for journal only. โ€”โ€” For Apple Watch owners who were about to buy an additional device. For anyone who's felt terrible after a good night's sleep and had no idea why. For people who want their health data to mean something. Normal is having the watch. This is Supernormal. โ€”โ€” IMPORTANT: Wellness app only. Not medical advice. Not diagnostic. Consult a healthcare provider before making health decisions. Apple Watch and Apple Health required. Core technology patent pending. Supernormal is designed and optimized for Apple Watch. It may work partially with other wearables that sync to Apple Health, but the full experience โ€” especially HRV-based recovery scoring, Biological Radar, and Biological Pace โ€” requires Apple Watch data.
