We have tried to make using iHeadache Online as intuitive as possible so that you do not need to read a user manual and can just jump right in and begin tracking your headaches. Just in case it is not as intuitive as we think we have a variety of help.
In the upper right corner of every screen you will see a help button that displays help for that particular screen. We also have a quickstart guide and user manual in case you want to make sure you know about every feature.
We are in the process of creating "How To" video tutorials to make it even easier to learn how to use iHeadache.
