The Bolus Calculator helps you count the carbohydrates in a meal and convert them into CU or BU – then applies the factor you entered yourself. Every intermediate value stays visible, so you can check each step yourself. 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. You work in carbohydrate units (CU) or bread units (BU) and with the factor you set yourself for each time of day. The app contributes no values of its own: it counts the carbohydrates and applies your factor to them. Every step of the calculation stays visible. The app displays all values of the calculation, so you can spot errors in the databases or in your own entries yourself. 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.
