I helped my wife try to manage her blood glucose for many years. We thought we had an idea of how things worked, but it was hard to find a decent app to help with BG management.
The old WaveSense app was a good start. It accepted time-stamped entries of blood glucose, food (carbs, fat, protein, calories), and short and long-term insulin. It had several weaknesses, including frequent crashes, taking forever to change time scales when a lot of data was present, mislabeling early morning activities as the next night.
My idea of a good / useful BG management app would include the following features:
- Allow entry of blood glucose, food carbs/fat/protein calories, insulin, exercise calories, stress, alcohol.
- Graph the BG data with a choice of time scales ranging from a fraction of a day, to all data (years). Allow scrolling in time with any particular scale.
- Don't limit things based on some artificial sense of how the data might look.
- Realize that this app can be an extremely helpful tool, when several measurements are made just a few minutes apart, for example, when recovering from a serious low BG, and measuring every 15 minutes or less.
- Optionally show insulin and food doses graphically with the BG plot, as translucent up (for food) and down (for insulin) histogram bars or vertical arrows, with the magnitude of the bars calculated from the user-entered sensitivity numbers (BG/carb and BG/insulin unit).
- Optionally calculate recommended fast-acting insulin dose, based on the current BG entry, other recent BG entries that help establish a trend, recent food intake and insulin dose entries.
- Export all data, or a specified time range, to email.
I'll update this, if I remember more details of what we thought would be helpful.
