Prodrom helps people living with migraine track their attacks, notice their
own patterns and prepare their medical appointments.
BUILT FOR THE HARD MOMENTS
A dark, minimal attack mode designed with photophobia in mind. Log the
essentials during an attack, fill in the rest once you feel better.
FOLLOW YOUR SIGNALS
Sleep, heart rate variability and resting heart rate, entered manually or
synced from Apple Health. Local atmospheric pressure. Menstrual cycle if you
enable that module. Prodrom compares your measurements with your own
personal average rather than a general norm.
SPOT YOUR REPORTED FACTORS
After each attack, note what was unusual in the previous 24 hours. Over
time, the app highlights what often appears before your attacks. These are
personal associations, never confirmed causes.
YOUR DATA STAYS WITH YOU
No account, no sign-up. Your health data is stored on your iPhone only.
Full JSON export and permanent deletion, free of charge and at any time.
PRODROM+
A 7-day free trial, then a monthly or yearly subscription.
A follow-up summary exported as a PDF for your doctor, with the figures a
neurologist looks for: headache days, days with acute medication, average
intensity and duration.
Full history beyond 30 days.
Factor associations across all of your recorded attacks.
Subscriptions renew automatically unless cancelled at least 24 hours before
the end of the current period. Management and cancellation are handled in
your Apple account settings.
DISCLAIMER
Prodrom is a tracking and data aggregation tool. The app provides no
diagnosis, measures no physiological data itself, and is in no way a
substitute for the advice of a healthcare professional. Always consult a
doctor to interpret your data or to change a treatment.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
WHAT'S NEW
- Cycle and Apple Health: if you turn on cycle tracking, Prodrom can now
read your period from Apple Health instead of asking you to enter it.
Permission is requested separately, only at that point.
- A cycle tile on the home screen shows the current day and the menstrual
window.
- Attacks occurring in that window appear in your signals, but only once a
personal association has been observed.
FIXES
- Several home screen elements overflowed at large text sizes, including
the attack logging button.
