A headache diary that isn't annoying. Your doctor said "keep a headache diary." You downloaded three apps. One wanted your email, your age, your sleep schedule, and a monthly subscription before you could log a single headache. One had so many fields it gave you a headache. One crashed. You just wanted to write down that your head hurts. HOW IT WORKS 1. Slide your intensity (0-10) 2. Tap where it hurts (forehead, temples, behind eyes, top of head, back of head, one side, neck, or all over) 3. Add a note if you want 4. Save That's it. No sign-up, no account, no onboarding quiz. WHAT YOU GET - Intensity scale from 0 to 10. Colour-coded categories: None, Mild, Moderate, Severe, Worst. - 8 head locations specific to where headaches actually happen. - History grouped by day. Spot patterns your doctor will actually find useful. - Trend charts for intensity and frequency over 7 days, 30 days, 3 months, or all time. - Doctor-ready PDF export. One tap. - Apple Watch companion app. Log from your wrist when a migraine hits. - iCloud sync across iPhone, iPad, and Apple Watch. - Large, clear interface designed for people who are already in pain. No subscription. No ads. No account required. Your data stays on your device and in your personal iCloud account. We don't have servers. There is nothing to sell.
