Somnalux vs Caffy

Somnalux is your personal sleep sanctuary — real healing frequencies, an AI-powered dream journal, and smart lights that ease you into sleep and wake you gently with the sunrise. GOLDEN SLEEP MODE Drift off to Solfeggio 528Hz, Schumann resonance, and other healing frequencies designed for deep, restful sleep. Try Solfeggio 528 free, anytime — Premium unlocks the full frequency library. SLEEP SOUNDS LIBRARY Layer rain, ocean, forest, wind, fire, and pink noise exactly how you like them, with sleep timers up to 8 hours so a sound can run your whole night. Rain is free to enjoy whenever you want — Premium unlocks the full library and lets you layer multiple sounds together. SNORE & NOISE TRACKING Heuristic, mic-based snore monitoring runs for your entire sleep session, not just while a sound is playing, and summarizes what it picked up each morning. A helpful nightly signal, not a medical measurement. AI DREAM JOURNAL Write or speak your dreams and let AI surface the patterns and recurring themes you'd otherwise miss. SMART LIGHT SUNRISE & WIND DOWN Wake up naturally with a gentle, gradual sunrise — and fall asleep the same way. A real 20-minute Wind Down ramp gradually dims your WiZ, Govee, or Philips Hue smart bulbs instead of snapping off, so bedtime feels as natural as waking up. VITALS & SLEEP METRICS Resting heart rate, HRV, respiratory rate, and sleep efficiency — pulled automatically from Apple Health and visualized in a live Sleep Metrics Radar, so you see what's actually driving good or bad sleep, not just hours logged. TONIGHT'S SLEEP FORECAST See a free nightly forecast based on barometric pressure trends. Premium unlocks the full weather-and-sleep correlation view, so you can see exactly how the atmosphere affects your rest over time. HEALTH INTEGRATION Your sleep stats sync automatically with Apple Health — no extra setup required. Somnalux is free to download, with Rain and Solfeggio 528 free to use, no time limit. Premium unlocks the full sound library, sound layering, every Golden Sleep frequency, smart light control, AI dream analysis, and the full weather-and-sleep correlation view. 14-day free trial, then $14.99/month or $69.99/year (founding member pricing, was $119.99) — cancel anytime.

Caffy shows your exact caffeine level right now, and tells you precisely when you'll be ready to sleep tonight. Using pharmacokinetic half-life models backed by FDA, EFSA & NIH research, Caffy calculates your personal caffeine curve based on your biology. WHAT MAKES CAFFY DIFFERENT: • Real-time caffeine decay curve: personalized to your age, gender & sensitivity • Sleep readiness score (0–100): know if tonight's sleep is at risk before bedtime • Focus window: see exactly when your caffeine peaks for maximum productivity • AI Weekly Analysis: AI reveals your personal caffeine patterns • Caffeine Detox Programs: structured plans to reduce dependence gradually • 6 Live Widgets: caffeine data on your Home Screen and Lock Screen • 5 Languages: English, Turkish, German, Spanish, Japanese PERSONALIZED HALF-LIFE: Your body processes caffeine differently. Caffy accounts for: • Pregnancy (9h / 12h / 18h half-life) • Oral contraceptive use (7h half-life) • Smoking status (3h half-life) • Age, gender & caffeine sensitivity SCIENCE-BACKED: Caffy's model uses the same caffeine decay formula cited by FDA, EFSA, NIH, and the Sleep Foundation. Not estimates, not averages. A 45-minute absorption phase followed by exponential decay based on your personal half-life. PRIVACY FIRST: No ads. No data selling.
