I would be great to not put period dates manually each time in the app. Apple Health app has a lot of period informations, maybe is it possible to sync period data with Health and also send to them info about headaches, bacause they also have pain tracker for headaches :)

Thank you for your feedback, there is an ongoing discussion on the best way to track your periods for a migraine tracking purpose. I will merge this discussion with it
