For migraine sufferers
Migraine Insight: Tracker helps identify the triggers of migraine headaches, whether it’s dark chocolate, red wine, aged cheese, or some combination of unforeseen factors. The $5 iOS-only journal app also helps the user log symptoms, and it can generate reports for your doctor.
Migraine Buddy, a free Android-compatible alternative, is very similar, but adds a sleep diary and a weather sensor that tracks local shifts in barometric pressure. The simple interface is designed for use during a migraine attack, and there’s a “bother me later” button that delays prompts until the migraine has passed.
N1-Headache goes beyond a diary, suggesting such preventive measures as changes in diet and exercise. The free app, backed by the National Headache Foundation, just requires that you allow the use of personal data in clinical studies.
