Diabetes Guides
Practical, plain-language guides on carb counting and insulin dosing — the foundations behind CarbTrack.
Carb Counting
What carbohydrate counting is and a simple, repeatable way to do it at every meal.
Carb-to-Insulin Ratio
What the carb-to-insulin ratio means and how the app uses it to estimate a dose.
Calculate Insulin Dose
The math behind a mealtime dose — carb dose plus correction — that CarbTrack automates.
Correction Factor
What a correction factor (insulin sensitivity factor) is and how it turns a high reading into a correction dose.
mmol/L vs mg/dL
The two blood glucose units, how to convert between them, and why consistency matters for dosing.
Net Carbs & Fiber
What net carbs are and whether to subtract fiber and sugar alcohols when you count carbs.
Reading Nutrition Labels
A step-by-step way to pull the carb count off any nutrition label and scale it to your portion.
