This app has been a Godsend for me! Never before has it been so easy for me to track my migraine attacks. Doctors always tell you to keep a headache diary, but its always been so difficult. This is easy to use even with migraine brain. You are able to customize it with your triggers, your meds, your symptoms etc. Then you can generate reports that you can customize. Now, I have never been able to get a report that made sense when I printed directly from the app, but I view the reports on my phone & put the info into a chart or document to share with my healthcare team. Thanks to this app I had a years worth of data & statistics regarding medication usage, pain levels, symptoms, disability level, missed activities etc for my application for disability through SSA. I also have statistics to give the doc for evaluating whether to continue with Botox for migraine treatments. Best app I have seen for tracking headaches.
