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.

CalFem is a calorie tracker built for the female body, which changes week to week. Snap a photo of your meal and CalFem's AI estimates the calories, protein, carbs, and fats in seconds. No barcode hunts, no endless food database. Your daily target then adjusts with your menstrual cycle, so you fuel your body based on the phase you are actually in. WHY CALFEM IS DIFFERENT Most calorie apps were built around a fixed 24-hour metabolism. Yours is not fixed. Estrogen and progesterone shift your energy, your cravings, and how your body uses food across four cycle phases. CalFem treats that as a core feature. Menstrual phase: softer targets and warmer meals. Rest is productive. Follicular phase: energy climbs and carbs work harder for you. Ovulation: your strength peak, so you can fuel the hardest sessions. Luteal phase: a slightly higher target, because your body burns more. Cravings get met, not shamed. SNAP IT. DONE. Point your camera at the plate. CalFem's AI reads the food, the portion, and the ingredients, then returns a complete log: calories, protein, carbs, fats, and a meal type (breakfast, lunch, dinner, or snack). Edit anything before saving. No bar codes and no database deep dives. Most logs take under 10 seconds. EVERYTHING IN ONE DASHBOARD Calorie ring and macro breakdown for today. Water tracker. Steps and active calories from Apple Health. Exercise log with MET based calorie burn. Weekly view of your last 7 days. Cycle ring with your current day, current phase, and a prediction of your next period. Weight progress chart with a 12 week projection toward your goal. PERSONALIZED FOR YOU Onboarding builds your plan with the Mifflin St Jeor equation tuned for female metabolism: BMR multiplied by activity factor, adjusted by your goal (lose, maintain, or gain), then split into macro targets. The result respects your cycle, your activity, and your pace. DESIGNED FOR HOW WOMEN EAT Diet preferences: everything, vegan, vegetarian, pescatarian, or low carb. A daily reminder at a time you set, on the weekdays you pick. Streaks and gentle badges that celebrate showing up, not perfection. YOUR DATA, YOUR CONTROL Logs live on your device first, then sync to your private, protected account so you can switch phones and keep your streak. Export everything as a file anytime. Delete it all in one tap. We never sell your data. APPLE HEALTH An optional, two tap connection reads steps, active calories, and workouts so your daily target stays accurate without logging cardio twice. CalFem never writes to Health. SUBSCRIPTION AND PRICING CalFem is free to download. AI meal scanning requires a CalFem Premium subscription. Pricing: Annual plan: 59.99 USD per year. Weekly plan: 4.99 USD per week. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.
