After looking through about four to five headache/migraine diary apps, I finally settled on this one, because this app seemed better connected with the actual medical community that understands headaches. From reading many other reviews, I saw that doctors actually recommended this using one.
Now that I own it, here are some pain points I have with this app:
-Terrible user interface (probably the most confusing app I own)… theres even a (?) question button meant to bring up a help screen for each page… which actually appears in front of other buttons! … also the (cancel) button is the only way to "go back" when usually, "cancel" means, "disregard this command".
-The paid version has a "NO ADS" banner on it, like the icon of a free app (totally lame).
-You can only set up to five custom triggers (why shouldnt you be able to set as many as you want?)
All that to say, its not pretty, but it gets the job done. Still though, Im not really looking forward to using it when I have a headache, thats for sure.
