i use this app to keep track of all appointments, medications, test results, medical letters and documents for several family members. When I am out of town I am able to email all of the information for each individual to an alternate caregiver or medical professionla in seconds right from my iphone. I use time in waiting rooms to update and have photographed test results and attached them as well. Easy to retrieve test info while at doctors office and ask relevant questions.I would recommend that to anyone looking after a family member or self and having to keep track of multiple pieces of medical information.
