SleepWizard — Your AI Sleep Coach Sleep trackers tell you what happened. SleepWizard tells you why. Most apps show you data: "You slept 6 hours." But they can't tell you why your deep sleep tanked or what to do about it. SleepWizard is different. It combines your Apple Watch biometrics with the context only you can provide — caffeine, alcohol, stress, screens, exercise — and uses AI to find patterns over weeks that you'd never spot yourself. The result? Insights like: "Your deep sleep drops 40% on nights you log alcohol after 7pm. This has happened 7 of the last 8 times." That's not generic advice. That's YOUR data telling YOUR story. WHAT MAKES SLEEPWIZARD DIFFERENT Data Fusion — Apple Watch captures sleep stages, HRV, heart rate, SpO2. You log the context: caffeine, alcohol, stress, screens, exercise. Somni (your AI coach) connects them over time. AI Coach That Actually Knows You — Somni analyzes 7 nights of detailed metrics, 30-day averages, and 7 days of contextual factors. Over 200 data points inform every response. Sleep Debt Tracking — 14-night rolling ledger shows exactly what you owe. Choose gradual (+15 min/night), moderate (+30 min), or aggressive (+45 min) payback plans. Smart Scheduling — Optimal bedtime recommendations based on your debt, chronotype, and goals. Quick Check-Ins — Evening: log substances, stress, screens, exercise in seconds. Morning: rate your mood and energy. Takes 30 seconds. Trends & Vitals — Track duration, efficiency, quality score, sleep stages, HR, HRV, respiratory rate, and SpO2 over 7/30/90 days. MEET SOMNI Somni is your AI sleep coach. Not a chatbot with a sleep FAQ — a coach that correlates your biometrics with your behaviors to find YOUR patterns and give YOU specific advice. Ask anything: "Why did I sleep badly last night?" "What's hurting my deep sleep?" "How do I pay back my sleep debt?" Somni uses your own API key from Anthropic (Claude) or OpenAI (ChatGPT). You choose your provider, you control your data. REQUIREMENTS iPhone with iOS 17+ Apple Watch with watchOS 10+ (for sleep tracking) Optional: Your own Claude or ChatGPT API key for AI coaching PRIVACY FIRST All sleep data stays on your device No account required No cloud uploads AI conversations go directly to your chosen provider — we never see them HealthKit data is never sold or shared SUBSCRIPTION INFORMATION SleepWizard Premium unlocks all features including sleep tracking, sleep debt management, AI coaching, smart scheduling, contextual check-ins, advanced trends, and data export.
