While I agree that the program is very promissing, I don't understand why people find it useful as it stands. Sure, the data entry interface is neat and clean and easy to use. However, the program does not enable me to extract the information I need to adjust my insulin scheme. As it stands the program is only a notebook and a small paper notebook is handier because you can carry that around and the data are more neatly arranged. The socalled summaries are merely listings. The program does not do statistics. There are no such things as graphs of an average day. There is no calculation of the amount of insulin needed per amount of carbs (for different times of the day). The program also lacks a feature, essential for pumpers, to insert a basic insulin scheme.
