Throb: Migraine Headache Diary

Log a migraine in one tap, even mid-attack, on a dark screen that won't hurt your eyes. Throb is a private migraine and headache diary you pay for once: no subscription, no account, no ads.

ABOUT THROB
Throb is a migraine and headache tracker for iPhone (iOS 18 or later) with an Apple Watch app. It is made for people with frequent or chronic migraine who need a reliable headache diary for themselves and for their doctor or neurologist. Everything is stored on the device; nothing is sent to the developer.

LOGGING
• Start an attack with one tap from the app, the Lock Screen widget, Control Center, the Action Button, Siri ("Log a migraine in Throb") or Apple Watch.
• Attack mode is a dark, low-light screen. Tap the pain level as it changes to draw a pain-over-time curve, and log every dose.
• Record where it hurts on a head map, plus symptoms, triggers, aura and prodrome, relief methods and notes.
• Whole-day entries for daily or continuous headache, with no start or end time.
• "Feeling one coming" notes early warning signs before the pain starts.
• Log medication doses taken outside an attack, including preventives.

FOR YOUR DOCTOR
• Doctor report PDF: headache days, attacks, duration, peak pain, acute-medication days, how often each medication helped and its median time to relief, MIDAS disability score and the HIT-6 questionnaire.
• A monthly count of acute-medication days, shown as information, never as an alarm.

INSIGHTS
• Calendar heat map, trends and a searchable list of every attack.
• Co-occurrence: which triggers and symptoms show up with your attacks. Patterns only, never claimed causes.
• Preventive treatment check: headache days per 30 days before versus since you started a preventive, with optional reminders from daily tablets to injections every few weeks.
• Barometric pressure trend from the iPhone's own barometer, optional alerts on sharp drops, and an optional pressure forecast from Apple Weather.

DATA AND PRIVACY
• Works fully offline. No account, no analytics, no third-party SDKs, no ads.
• Optional iCloud sync through your own private iCloud database.
• Optional Apple Health: reads sleep and menstrual cycle, writes headache events.
• Automatic local backups with restore, plus CSV and JSON export.
• Import from a Migraine Buddy CSV export or a headache spreadsheet.
• Face ID lock.

PRICE
Free: logging, attack mode, full history, calendar, search, backups, iCloud sync, export, Face ID lock and a doctor report for the last 30 days.
One-time purchase, no subscription: doctor reports for any date range and all insights.

LANGUAGES

WHAT THROB IS NOT
Throb does not diagnose, predict or treat migraine and is not a medical device. It records what you log so that you and your clinician can see the pattern. No streaks, no gamification, no community feed, no notification spam.
