won't classify correctly – iHeadache - Free Headache & Migraine Diary App Review

I thought this would help me track my headache patterns and their respective triggers, but, for the life of me, I can't figure out what criteria this thing uses to classify headaches. Yes, I know it was developed by a neurologist. However, I entered the following symptoms: preceded by aura, primarily one-sided, throbbing, worse with movement, sensitivity to light & sound, nausea... and it was logged as "unclassified headache". Out of curiosity, I tried a few other symptom combinations, and none of them even registered as "probable migraine". If I had the option to write in classifications, I wouldn't complain. But, that's not an option. All of my headaches would be logged as "unclassified". Not helpful when I was trying to track migraine, tension, and mixed tension-migraine headaches.
