About this app

This app is designed for simple calculations of insulin doses in the Canadian home and school setting (although calculations can also be done in U.S. mg/dL blood glucose units). There are 5 screens available: The Simple Insulin Bolus screen calculates an insulin dose for people on multiple daily injections (MDI) based on carb ratio, correction/sensitivity factor (ISF), target BG (the default is 6 mmol/L or 100 mg/dL for daytime, and 8 mmol/L or 120 mg/dL for bedtime), carbs to be consumed, and current BG. The Simple Insulin Scale screen generates a simplified insulin sliding scale for people who are on a fixed dose of carbs at a meal, based on baseline insulin dose, ISF, and target BG. The Full Sliding Scale screen generates a full insulin scale (in CSV, HTML or PDF format) for people on MDI based on carb ratio, ISF, and target BG. The Correcting for Arrows screen allows CGMS users to calculate an increase or decrease in insulin dose (or carbs) to account for positive or negative direction arrows. The School Resources screen contains links to websites devoted to the care of Canadian children with diabetes in the school setting.

Ratings and reviews

This app is perfect for me. It's easy to use and really effective in factoring in my current blood glucose reading. Best app ever. Well done Dr. Metzger! I use this 4 times a day. So handy. It could be even more useful if it calculated (and saved for graphing), total daily usage of insulin so that the ratios can be improved.

my daughter is a new type 1 diabetic and lemme tell you. I LOVE this!!! and her entire Endo team recommended this app to me. thanks doc!! you're saving lives with this one! medical professionals and civilians alike!!!

To be fair, I only used it once. But it works, and it is incredibly handy having different ratios depending on time of day. I used to use a sliding scale, but was forced to figure out a new one after a drastic drop in insulin dosages. Now I can easily tweak stuff and adjust as needed. I would pay for this if given the option. Thank you for making this software!
