Add 3-month average in Blood Glucose Tracker

I am a nurse and I love this app. I like the ease of entering my blood sugar ready and being able to view it on a graph to see the ups and downs.

I would like to see the addition of a way to take the blood sugar readings for the previous three months and give an average of those numbers. If this app had the ability to AVERAGE the blood sugars over the last 3 months, this would allow people to have a better idea of how well they are managing their blood sugar.

In healthcare, we check a hemoglobin A1c. This test is used to help determine the average blood sugar over the previous three months; this gives an accurate measure for how well the blood sugar control had been. By adding this feature, the app would, in my estimation, go from a very good app to an excellent app.
