I tried keeping a log many years age I have also tried several of the apps out there. Abandoned it because it was too depressing. I thought with enough data I could plan and manage the beast. Tracked barometric pressure, moon phases, diet in addition to O2 Use, imitrex injections, steroids and Vit D protocol.
I decided it was futile and depressing to see how much of my quality of life was given up to the beast. For me, nothing seemed a pattern even though I was convinced there was one. In cycle even smelling alcohol set me off but that was the only reliable trigger. As most of us no when in cycle rationale reason gives way to scattered thought and emotional upheaval.
Live life the best I can using what grows from the earth, O2 and inject when desperate
Keeping accounts only gives the beast more attention than it deserves.
