The diary that learns
Most headache diaries are a chore that ends in a spreadsheet nobody reads. Erin's diary feeds directly into your plan, and into the summaries your clinician sees.
Tracking with a purpose
Every entry is in service of a better plan, not data for its own sake.
Log an attack in seconds
Capture timing, intensity, location, aura and what you took: fast enough to do mid-attack, structured enough to mean something later.
Connect your wearables
Sleep, heart-rate variability and activity flow in automatically, so patterns surface without extra effort from you.
Weather & environment
Pressure, temperature and other environmental signals are tracked alongside your attacks to test the triggers you suspect.
See what actually helps
Over time the diary separates signal from folklore, showing which changes move your numbers and which don't.
The basic diary is free. The clever bits come with Standard.
Log attacks, pain location and symptoms on any plan. Voice-activated logging and phone health data (weather, exercise, HRV, sleep) are included with the Standard plan.
