Fantastic!
This is a very useful well designed app for migraines and other types of headaches. I was using the free version (cap of 3 diaries max) for a month and just recently upgraded to the paid version. The app allows me and my dr to keep track of my migraines on a long term basis and makes it much easier to keep a diary than the old pen and paper format. Get the paid version as the free trial is limited to only tracking 3 headaches.
A+
