## What is Bolus Calculator?

The Bolus Calculator helps you count carbs (CU/BU) and work out your meal bolus from your own bolus factors – showing every step of the calculation so you always stay in control. No sign-up, no registration: your data stays private. You can sync several devices – perfect for managing your child's meals together as two parents. Scan a food or search by keyword, enter the amount, done – the app knows tens of thousands of products and their carb content, and you can save meals as templates. And you decide for yourself: buy once instead of subscribing. 

The app can be used with your individual bolus factors as well as carbohydrate units (CU) or bread units (BU). This way, the correct meal bolus is calculated for you at any time. The app displays all values of the calculation, so that even in case of errors in the databases or in your entries, you always remain in control!

In addition, you can synchronize multiple mobile devices and thus, for example, manage the meals of your child with two parents together. The app does not require any registration and protects your private data in a very secure way!
