Migraineurs, which app do you use to record your migraines?

Hello folks,

I get migraines at least twice a month (down from every 2nd day for last 4 years), still I want to keep a record of migraines and other parameters related to it. I checked app store and there are a few apps but even after paying, many of them are just rubbish.

I am curious if I missed any app that is basic design and syncs data with online server?

I currently use Headache Diary Lite but I am looking for an alternative. Any suggestions?

Many thanks in advance.

 

Just wanted to note here for those who may stop by later searching the same. Migraine Notebook developed by GlaxoSmithKline PLC comes close to what an ideal app should be.
Not too sure why it states, for US residents only but I guess everyone can use it.
