InsuCalc: Carbs, Fats & Bolus

Make split-bolus dosing for your type 1 diabetes finally make sense.

InsuCalc converts the carbs, fats, and protein of any meal into equivalent carb portions and tells you the exact split between initial bolus and extended bolus — plus the total absorption time. Built specifically for fatty, complex meals (pizza, burgers, aged cheese) where a single upfront bolus falls short.

THE METHOD

InsuCalc is based on the dual bolus method developed by the Pediatric Diabetes Department at the Hospital General Universitario de Alicante (Spain). This is not a medical device — it is an orientative calculator that supports your clinical judgment and your care team's guidance.

BUILT FOR COMPLEX MEALS

A pizza is not just carbs. The fat and protein delay absorption and require splitting the bolus over time. InsuCalc automatically calculates:

- Equivalent carbohydrate portions
- Initial bolus percentage (at the start of the meal)
- Extended bolus percentage
- Total absorption time

AI FOOD ANALYSIS (Premium)

IMPORTANT

InsuCalc is an informational, orientative tool. It does NOT calculate or display insulin units. It does NOT replace your medical team's judgment, your diabetes education, or any approved medical device. Treatment decisions should always be made with your endocrinologist or diabetes educator. When in doubt, consult a healthcare professional.

InsuCalc was born from real-life experience with type 1 diabetes. It is built for people who already know how to count carbs and want to fine-tune dose splitting for complex meals.
