I suffer from a very complicated migraine and I decided to do a Migraine app so I could see when my attacks occured. I wanted the app to be as mobile as possible. When I bought my Palm a couple of years ago I could begin to develop MigraineMemos. Nowadays I use the MMemos myself on my Treo 600. I hope, It will help you get some order of your migraine attacks but use the program at your own risk. Features:keep diary; enter attacks, triggers, comments and compare it with the diary; get statistics, secure days, min, max, average, and total; enter medication, evaluate; enter bad and good doctors; draw your own migraine; print reports in Windows, to show to your doctors.
