They don't allow you to find your triggers, understand your migraine AND find ways to communicate with your doctor...only 2 of them...can't do a third, as it's restricted by the app. You need to pick and choose which is more important, understanding your migraine or finding ways to communicate to your doctor about your headaches. THEN, after you've decided those restrictive options, the app freezes. Really good job, developers...bravo! Don't download this waste of an app.
