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.

Your posture is quietly stealing your height. Most people lose 2-4cm to forward head and rounded shoulders — and never find out. Posture Fix takes 3 photos and tells you exactly what's wrong, how much height you've lost, and what to do about it. HOW IT WORKS 1. SCAN — Take 3 photos. On-device AI maps your alignment and finds every deviation: forward head, rounded shoulders, anterior pelvic tilt, winged scapula, kyphosis and more. 2. SEE THE COST — Get your real height versus your current height. See which misalignments are responsible for the difference, and what each one is doing to your spine long-term. 3. FIX IT — Get a program built from your scan, not a generic template. Only the exercises your body actually needs, 5 to 15 minutes a day. 4. TRACK — Re-scan any time. Watch the numbers move. WHAT MAKES IT DIFFERENT • AI posture analysis from 3 photos — no wearables, no subscriptions to hardware • Height loss detection — see what your posture is costing you in centimetres • Risk analysis — understand what each misalignment leads to if left alone • A program generated from YOUR scan, not a one-size-fits-all routine • Everything processes on your device. Your photos never leave your phone. WHO IT'S FOR • Desk workers and students with tech neck • Anyone who catches their reflection and doesn't like the slouch • Lifters whose posture is limiting their overhead position • People with recurring neck, shoulder or lower back tightness • Anyone who suspects they're shorter than they should be WHAT'S INSIDE • Full-body AI posture scan • Height forecast and loss breakdown • 6 posture-type analysis with severity scoring • Guided stretching and mobility routines with video • Custom program builder • Daily reminders and streak tracking • Progress history and re-scan comparison Posture takes years to break and weeks to improve. The sooner you know what's wrong, the less there is to undo. Download Posture Fix and run your first scan in under two minutes. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings.
