I know the doctors who designed this app, and have been tracking my headaches for over a month now on a beta version. I was using massive amounts of Motrin, sumatriptan, and Tylenol and still having multiple migraines a week. I showed the data to my neurologist, and it led to me starting a daily medication. I have significantly less headaches now. I strongly recommend this app for my friends, family, and patients. It is very easy to use and provides useful information for your physician to adjust medications.
