This is ridiculous I am a physician myself and I’ve never seen an app like this where you cannot register and it’s on the iPhone apps apple should get rid of this it’s misleading because it seems like you can only use it if you’re in a study I hope I didn’t pay anything for it big waste of time and frustrating it’s giving me a migraine

Requires a login and password, but no where to register. Looks like it may only be available to study participants, which is ironic because the article I read about the App states that researchers believe an inexpensive readily available smartphone app would be beneficial to migraine sufferers. Would be hugely beneficial, if only they allowed access to the app!

After taking 11 minutes to download on high-speed Internet, there is no way to login to this app. I see the same problem was mentioned three years ago. Why this app is still offered is beyond me when it can’t be used.

Disappointed with this APP. Article is interesting. Gives you hope for relief. Then you can’t get even participate even when article says it’s great for headache issues. No mention that you have to be in a study
