My Simple Headache Tracker vs Headache Companion Usage & Stats

Headache Companion lets you track your migraine attacks and other headaches, while keeping your data private. Record detailed attacks, medications taken, and activities, such as water consumption and exercise. See the data you've logged in a detailed overview, organized by a custom time-frame, to better understand it, or show it to your doctor. You can also take notes for yourself and for your doctor. Headache Companion does not collect any of your data, so it can never be sold or compromised.
