Log it in two taps
When an attack starts, two taps save the time. Fill in the rest once it's passed.
Migraine and headache
Record each attack as it happens, with how bad it was, any aura, what you took and what helped. Then give your doctor a clear picture of what's been happening between appointments.
Coming soon to iPhone and Android.
Get help straight away if a headache is sudden and severe, or comes with other symptoms that worry you: call your local emergency number (000 in Australia) and ask for an ambulance. Go to your nearest emergency department if a headache comes with a fever, a stiff neck, confusion or a change in personality, blurred or double vision, loss of balance or a seizure.
Migraine can bring severe headaches, nausea, vomiting, or sensitivity to light or sound, and some people get an aura first: a change in their vision, speech or sensation. The migraine template asks about each attack, so the details are written down while they're fresh. Fill in what you can and skip anything you don't know. You can always come back later.

Record each medicine and the time you took it, so you and your doctor can see what helped and how quickly.
Note your cycle day with each attack, so you can see whether attacks follow your periods.
Some things can set off a migraine attack, such as missing meals, too much or too little sleep, or stress. Tap any that were going on. Over time, your report shows how often each one came up, as plain counts.
