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 20 languages: English, German, French, Italian, Spanish, Japanese, Chinese (Simplified and Traditional), Korean, Portuguese (Brazil), Russian, Arabic, Dutch, Turkish, Polish, Swedish, Hindi, Indonesian, Thai and Vietnamese. 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.
