I am a nurse and I love this app for tracking things like blood pressure, weight, medications, and blood glucose readings. I recommend this app to patients.
My suggestion is that within the blood glucose reading options a way to calculate an A1c test be added as this is the number used to determine overall glycemic control. I think it would be a fairly easy addition as all it entails is averaging the blood sugar reading over the past 3 months.
Very thankful for this app in helping patients have a place to record blood sugars and see them on a graph.
