Most headaches have a pattern. You just cannot see it without a journal. HeadacheJournalOS is a 30-second-per-headache log that turns weeks of vague pain into a clear chart - which weekday, what time, after how many screen hours, with how much sleep, with how much water. Spot your real triggers. Save what helps. Walk into a doctor visit with data, not vibes.

Disclaimer: This is a personal pattern-spotting tool, not medical advice. If you have a sudden severe thunderclap headache (worst-of-life), call 911 - it can signal stroke or aneurysm. New aura, slurred speech, weakness, vision loss, fever with stiff neck, headache after head trauma, or first-ever bad headache after age 50 also warrant ER. If you have 8+ headache days a month or migraine with aura, work with a neurologist - this app is for everyday tension, sinus, dehydration, screen, and posture headaches.
