this app has served me well in documenting chronic pain and medication doses. I was thrilled to find an app that would both allow me to make pain entries and log meds... but when I open the list of meds that I have taken the app freezes almost without fail if I try to look beyond two days prior. very frustrating especially since I upgraded to the full feature app. also, I am not able to email medication logs, only pain logs which is very unhelpful.
