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 — 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. —— BIOLOGICAL RESERVE Unlike a static morning score, your Reserve depletes in real time as you train and move — 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 — 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. —— 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. —— 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 — especially HRV-based recovery scoring, Biological Radar, and Biological Pace — requires Apple Watch data.

Most sleep apps hand you a number and walk away. Lull tells you why you slept the way you did — and what to change tonight. TRACKING THAT RUNS ITSELF Wear your watch to bed and you're done. Lull reads your nights from Apple Health — no timer to start, no button to press. You wake up and last night is already scored. A SLEEP SCORE THAT EXPLAINS ITSELF One number, 0 to 100, built on sleep science: duration, efficiency, restlessness, deep and REM sleep — every target adjusted for your age. Open any night to see where the points came from and where they went. FIND WHAT'S REALLY RUINING YOUR NIGHTS Coffee at 6pm. A late workout. Two glasses of wine. A warm shower. Log a habit in seconds and Lull lines it up against your real sleep data, night after night, until the pattern is impossible to miss. Not generic advice — your body, your tolerances. Learn what you get away with, and what quietly costs you an hour of deep sleep. FALL ASLEEP FASTER, STARTING TONIGHT Guided techniques you can run in bed: 4-7-8 breathing, the military method, the cognitive shuffle, the 20-minute rule and warm-shower timing. Lull keeps score of which ones actually work for you. AN AI COACH THAT KNOWS YOUR NUMBERS Ask why Tuesday fell apart, or what to do about a 3am wake-up. Your coach answers from your own scores, habits and trends — never from a generic script. FOUR WEEKS TO BETTER SLEEP A guided program built on CBT-I, the clinical gold standard for insomnia: tighten your sleep window, rebuild sleep pressure, then widen it again as your nights consolidate. PUT THE PHONE DOWN Pick apps to block during your wind-down window so your phone stops fighting your bedtime. Your choices never leave your device — Lull can't see which apps you picked. SEE THE WHOLE PICTURE Sleep debt, social jetlag, bedtime consistency and weekly trends, in plain language. Spot the factor that has been dragging your sleep down all month — and the habit that helps more than you thought. MORNING CHECK-IN A gentle prompt after you wake ties how you feel to how you slept, so your scores reflect real life and not just sensor data. AT A GLANCE Home Screen and Lock Screen widgets plus an Apple Watch complication keep last night's score one look away. PRIVATE BY DESIGN Your sleep data stays in Apple Health, on your device. The apps you pick for wind-down never leave it. LULL PRO Tracking and your nightly score are free. Pro unlocks the AI coach, full trends and analysis, the 4-week program and wind-down blocking: 3-day free trial, then $1.99/week.
