Easiest to use.

I tried several and this is easiest to use. I believe its the only one with a dose calculator, the export pdf feature is really well done, the display is the easiest to read. I finally found one Im happy with and its pretty reasonably priced.
adddendum. Still loving it after 2 months and still havent found a better one. But it would be great to sync with my other devices. Glucose buddy does that but its not anywhere near as nice.

Addendum. It would be even better if the dose calculator automatically worked form the glucose input page so you didnt have to out blood sugar in twice to get your dose and save your glucose.
