About: KPumpe is a diabetes diary application with support for reading records from your glucometer. It supports the Onetouch Ultra and other glucometers where glucomodule plugins are available.
I haven't used this one yet, but I plan on installing it at work, and getting my patients to start using their glucose monitoring machines more.
