Haven
Read full descriptionHide full description
Stop guessing your triggers. Start predicting them. Living with migraines is chaos. Tracking them shouldn't be. Haven is the intelligent companion designed to help you find calm in the storm. We combine a photophobia-friendly Attack Mode with powerful AI Trigger Discovery to reveal the hidden patterns behind your pain—hormones, weather, sleep, and more. WHY HAVEN IS DIFFERENT: Most apps feel like spreadsheets. Haven feels like relief. It’s designed for the moment you are in pain (dark, simple, 1-tap) and the moment you are well (insightful, proactive). KEY FEATURES: 1-Tap Attack Mode Designed for photophobia. A pitch-black OLED interface with massive buttons lets you log an attack in seconds without hurting your eyes. AI Trigger Discovery Our engine analyzes 37+ factors (sleep, weather, food, stress) to find your personal triggers. Trigger Map: See what increases your risk. Protector Map: Discover habits that keep you pain-free. Cycle Syncing & Hormones 60% of migraines are hormonal. Haven automatically correlates your attacks with your menstrual cycle phases (Follicular, Ovulatory, Luteal) to predict hormonal peaks. Sage: Your AI Companion Chat with Sage to understand your data. "How does rain affect my migraines?" or "Show me my medication usage." Sage observes patterns and asks the right questions—never prescribing, just guiding. METICULOUS TRACKING: Weather & Barometer: Auto-alerts when pressure drops significantly. 8-Zone Head Map: Log exact pain locations (behind eyes, neck, temples). Smart Prodrome: Track early warning signs like yawning or cravings. Doctor Reports: Generate PDF reports with your MIDAS score for your neurologist.
