Substrata vs Headache + Migraine Tracker

Wake up tired without knowing why? Headaches that hit out of nowhere? Substrata watches the noise, weather, and air around you, then pairs it with your sleep, heart rate, and HRV — so you can see exactly what's affecting how you feel. The analysis runs entirely on your iPhone using Apple Intelligence. After about two weeks, the on-device correlation engine starts surfacing connections — barometric pressure drops that match your migraine days, bedroom noise that quietly steals your deep sleep, weather patterns that drag down your HRV. Plain-English explanations you could share with your doctor. YOUR SLEEP, EXPLAINED - Sleep Condition Score: how well your bedroom actually treated you (noise, temperature, humidity, pressure stability) - Pairs with HealthKit sleep data + Apple Watch wrist temperature - Hourly, daily, weekly charts with WHO/EPA threshold zones color-coded HEADACHE & SYMPTOM TRIGGERS - Tap to log a headache (migraine, tension, cluster) with severity and notes - After 20-30 logged events, your personal trigger profile starts building - Predictive alerts when conditions match your past headache patterns - Also tracks allergies, mood, joint pain, energy ON-DEVICE INTELLIGENCE - All correlation analysis runs on your iPhone - Weather comes from Apple WeatherKit, using your approximate location - No accounts. No third-party analytics SDKs. - Microphone is not used in production; noise data comes from Apple Watch - Privacy nutrition label: no data collected WHAT YOU GET WITH PREMIUM - Every correlation the engine finds (free tier shows your top one) - Personal headache trigger profile + predictive alerts - AI-generated insight narratives - PDF and CSV export — bring a real report to your doctor - History beyond 30 days Requires iPhone with iOS 26.2 or later and an Apple Intelligence-capable device for AI insights. Apple Watch strongly recommended for environmental noise, HRV, and sleep-stage data; works without a Watch using weather, sleep duration, and headphone audio. Substrata is not a medical device and does not provide medical advice. It explores potential connections between environmental and health data for personal review. Consult a healthcare provider for diagnosis or treatment.

Understand and manage your migraines with MigraCal, the comprehensive trigger tracking and pattern analysis app designed for people living with migraines. TRACK YOUR TRIGGERS Log potential migraine triggers including food (tyramine, nitrates, MSG, caffeine, alcohol, artificial sweeteners), sleep quality, stress levels, weather changes, menstrual cycle, screen time, and more. The more you log, the better MigraCal identifies your personal patterns. AI FOOD TRIGGER SCANNER Snap a photo of your meal and instantly assess common dietary migraine triggers. Our AI identifies tyramine-rich foods, nitrate sources, MSG-like ingredients, and other known trigger compounds. PATTERN ANALYSIS MigraCal analyzes your diary entries over time to reveal correlations you might miss — like migraines always following poor sleep combined with aged cheese, or weather changes triggering attacks. MIGRAINE DIARY Record attack characteristics: pain level, location, duration, aura symptoms, associated nausea, and what helped. Build a comprehensive history to share with your neurologist.
