## BolusCalc Description
his 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.

## BolusCalc Reviews in United States

### ****- "Simple, easy to understand"
I like that it’s set up for three different methods of calculation depending on your insulin sensitivity at various times of the day.  I also like that it saves your settings instead of re-entering them every time.  

Would love an and be willing to pay a decent amount for IOB and exercise adjustment to be included as well as it keeping your records permanently in the app for your review.  I had the Rapid Calc app but lost it when I got a new phone and it’s no longer available in the USA App Store. I’m dying for someone to duplicate it.  But in the meantime, this is about the best anyone has to offer here in the US App Store,
not to mention, it’s free with no adds.  Can’t beat that.

### ***-- "Add the 4 separate meals back"
I’ve been using this app for years and my daughter recently downloaded this on her phone and ours is different mines has 4 separate meals which is great because her ratios are different. But her app only has 1 setting and it’s not helpful please bring the 4 different settings back breakfast lunch dinner bed
-- Saunwalk, 2024-06-05

### ***-- "Insulin on Board"
Are you working to add in the calculations the Insulin in Board?  That would be so helpful.
-- KarMikPatTom, 2023-12-05

### ***-- "Good app but has been getting stuck"
We’ve used this app for quite awhile now but for the past month or so it’s been getting “frozen”. I have to close out everything and start over. Is there a fix for this?
-- MomReynolds, 2023-02-08

### **--- "Doesn’t seem to work"
Whenever i enter my BGL and tap Calculate the app switches to an all white screen and freezes. Have to force quit app to start over again. It’s a shame because the app seems to do exactly what I want in an insulin calculator app.
-- gary.keith, 2022-10-24

### ***** "Awesome app!"
Developer is very responsive to customer input!
