YOUR PERSONAL HEADACHE EARLY WARNING SYSTEM Phoebe predicts headaches before they hit. Using Apple Watch biometrics and real-time atmospheric intelligence, Phoebe forecasts your headache risk up to 7 days ahead, so you can act before the pain arrives. Most headache/migraine apps only record pain after the fact. Phoebe predicts it before it happens. HOW IT WORKS Your Apple Watch passively collects sleep, HRV, heart rate, and activity data via HealthKit. Meanwhile, WeatherKit tracks barometric pressure, humidity, and temperature at your exact GPS coordinates - updated hourly. Our ML engine blends 27 biometric and environmental features into a personalized Blended Risk Score that improves with every diary entry you log. FREE FEATURES - Blended Risk Forecast: See today's and tomorrow's migraine risk on your Dashboard, powered by our ML prediction engine combining health data and atmospheric signals. - BioWeather Intelligence: 15 biometeorological conditions analyzed at your coordinates. Understand how pressure drops, humidity spikes, and temperature swings affect you personally. - 7-Day Forecast: View your risk for the entire week ahead. A pressure front arriving Thursday? You'll know by Tuesday. - Voice Diary: Hold the button and speak. "Severe right side, started an hour ago, took sumatriptan." Phoebe logs severity, location, triggers, and medication โ€” without a single tap. Built for when it hurts too much to look at a screen. - Smart Journal: Every headache, trigger, symptom, and medication tracked with timestamps, pain location mapping, and severity scoring. Weekly trend charts show your patterns over time. - Ask Phoebe AI Chat: Ask questions like "What are my top triggers?" or "How did I sleep this week?" Phoebe answers using only your diary data - no internet knowledge, no guessing. - MIDAS Assessment: Complete the clinically validated Migraine Disability Assessment to measure how migraines impact your daily life. Share results directly with your neurologist. - Contextual Notifications: Phoebe alerts you when risk factors align - pressure dropping overnight while your HRV is declining. Act before the pain window opens. - Apple Watch Integration: Deep HealthKit support for sleep analysis, heart rate variability, resting heart rate, steps, and active energy. Your existing Watch does everything. PREMIUM SUBSCRIPTION (optional) The following features require an active subscription: - Deep AI Analysis: Advanced pattern recognition across your biometric, atmospheric, and diary data to surface compound triggers you wouldn't spot manually. - Correlated Insights: Cross-referenced analysis showing how sleep, weather, and your logged triggers interact to drive headache events. - PDF Medical Reports: Clinical-grade summaries covering your headache frequency, severity trends, trigger analysis, and medication effectiveness. One tap, hand it to your neurologist. All core features listed above under "FREE FEATURES" are available at no cost. The optional subscription unlocks the premium features listed above. PRIVACY FIRST No ads. No data selling. No third-party trackers. Your health data stays on your device and our encrypted servers. Request complete deletion anytime. ABOUT Named after the Greek Titaness of the Moon - because migraines, like tides, follow invisible rhythms. Built with care by Empedoc Labs.
