Carb Candy is an app based on Chris Hannemann's push-button-get-candy project. Carb Candy calculates how much candy (skittles) you need to eat based on your current blood sugar level to your intended target level.
All calculation formulas are based on how-much-candy for more detailed documentation click-here
The basic formula for determining the total amount of candy:
totalSkittles = (targetGlucose - currentGlucose) / ((insulinSensitivity/carbRatio) x carbsPerSkittle)
All calculation are using units: mg/dL
