iBolusCalc is an application that calculates insulin Bolus dosage for diabetics based on user inputs. The suggested calculation is based on user settings that are typically provided by a doctor or diabetes educator. NO more charts; more accurate insulin dosage calculations, QUICKLY! Your own personal insulin calculator. Great for teenagers, Mom and Dad with children with type 1 or anyone that uses insulin pens and need to calculate for insulin bolus.
FOUR numbers are needed for the initial setup:

# 1-- Target Blood Glucose: Target in mg/dL

# 2 -- Exercise Glucose Ratio: Reflects the number of blood glucose points mg/dL for 30 minutes of exercise.

# 3 -- Insulin Sensitivity Ratio: Number of Blood Glucose mg/dL per 1 unit of bolus insulin.

# 4 -- Carbohydrate to Insulin Ratio: Number of carbohydrates in grams, to balance 1 unit of bolus insulin.

Once the initial setup is complete then iBolusCalc is ready for use.
Step 1: Diabetic takes blood glucose reading with tester
Step 2: Enter blood glucose reading into iBolusCalc
Step 3: Enter estimated carbs to eat and any exercise within the next 30 minutes into iBolusCalc.
Step 4: Press “CALCULATE” iBolusCalc provides suggested insulin bolus.

Important: The suggested insulin bolus is based on user supplied data (one time entry that can be changed as diabetic’s ratios change), and not intended to replace calculations for insulin requirements as instructed by your doctor or diabetes educator.

Not sure about calculation

When I enter a Current Blood Glucose that is lower than Target Blood Glucose the calculated bolus is reduced. Is this the expected behavior? If so, would it be possible to add the abilty to switch this off? The plan I'm using does not reduce the bolus when under the target glucose. Thanks.


decent app

this is very solid IF and only if your blood sugar readings are above your tarhet blood sugar goals, otherwise, it doesn’t figure the hard number whatsoever!
I like it, but isn’t “complete”. Once that happens, 5 of 5 and off the charts 🎉


Doesn't work with IOS 9.2

I have had this app since IOS 6 on my iphone 4S. It is/was my favorite for calculating insulin dosage of the ones I have found and used. It worked great on my iphone 6 with IOS 8 up until I recently upgraded to IOS 9.2. Now I get the black screen as others have reported. I would not recommend a new purchase to anyone until it is fixed. If you look at the dates of some of the other reviews reporting this same problem it does not appear that a fix is coming soon!
