Such an interesting question. Thanks so much for posing it and I will be interested to see the feedback from our community. I have some questions about how such a thing could be designed as every person with migraine has a unique set of triggers that often evolve and change with time. Also how would the app track the multiple symptoms we experience without someone having to proactively enter them as they are unfolding. We talk a lot here about how prodromes are frequently difficult to track as they are happening (like brain fog, irritability, forgetfulness) so they can be easy to miss and easier to be seen in retrospect. BUT- if the questions about how it could be done could be answered, I think having a signal that a migraine attack is pending before it hits would certainly be helpful as treating an attack in its infancy increases its chances of stopping it in its tracks. Thanks for the question! Warmly, Holly (migraine.com team).
