Description
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 4 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 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.

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!

Dr. Metzger, thank you for making this app, it's very helpful for our new adventure. Is the source available on GitHub or other similar software? Is there a way I can provide additional feedback outside the Google reviews?
★★★★★Peter Tyrrell· Mar 31, 2021
This app seems to be targeted at children, I am 70 years old, and it is really helping me flatten my blood glucose level, thank you. Requests: A "drop down" carb ratio selection (Simple Insulin Bolus) for (say) three carb ratios that could each be tweaked for best results. A great app. Thank you for your work, but I cannot get the new drop bolus options to work.

Inadequate guidance for using the app, no "HELP" link. I don't know if it's really any good
★☆☆☆☆Alivia Wood· Mar 7, 2023
It is not a very good app sometimes I would put my carbs and bloudsugar in, and it would miscalculate it and overall it's really confusing 😕 😤
